Hey Jay Z, I flew two Century Series aircraft. The F-102A, T-33 and T-33AT which was the attack version. The F-102 was famous for compressor stalls. You could not throttle burst it while stationary. These were not big stalls and we called them choo choo stalls which sounded like someone pounding a hammer on the fuselage. All you had to do was slow down your throttle a tiny bit. Startup was not computer controlled like today's jets. The F-102 had an air turbine starter. You needed a ground power cart. The drill was spin, spark and then spray. Same with the T-33 except it had a starter generator. I now instruct in a Cessna Grand Caravan with a Canadian built PW PT-6A engine. This is only simulator but has a real cockpit, motion and sound with Garmin 1000 display. You are actually in a CRV. I also flew for 8 years in the Dornier 328 which had PW 119B engines. What a beautiful engine. You guys up there in the north do great work. BTW j Z, I'm not sure where you are but Ottawa was one of me best overnights.
When I was in the Air National Guard we had F-100's with J-57's in them. We didn't have a test cell. We had to taxi or tow the F-100 with the tail removed out to a pad and chain the airplane down to test the engine. The hydraulic lines going to the tail had to be capped off in order to pressurize the hydraulic system. In the winter time we used to throw snowballs into the flame when the engine was in afterburner. And it was nice to stand close to it on a cold winter's day.
The Fresno ANG has an F-100 on display. Too bad ever since 9/11 they surrounded the place with security fence and now it's not accessable to the public.
I remember that time AgentJayZ got sucked through an APU he was testing and turned into a lovely Chili con Carne. Some said the chili was too lean and lacked spice. Those reviewers, in my opinion, missed the subtly of the hydrocarbon smokiness and stinging snarky aftertaste.

Wow, amazing!! That's every little boys dream (ok, it's also this 37 year old big boy's dream) to have a real fighter jet cockpit to flip switches in!!
Hiller Aviation Museum in San Carlos had an A-4 avail to sit in as of 20 years ago. They also had the nose of the SST, but I heard that one was shipped up north recently.
People who call u idiots are just idiots themselves being jealous of your work! Fine videos, I learn a lot from them while studying to become an aircraft technician!
glad that you had the fun of getting in a Sabre and running the engine! I spent some time as an avionics tech on A-4 Skyhawks, and had a license to run the engine. Definitely a fun thing to do... until the time my ground crew gave me the fire sign! Turned out to not be a fire, but sure was a bit of excitement that I didn't need. :-)
Thanks Jay great distraction given the stress in the world at the moment. Stating a gas turbine in the cockpit of a fighter is an experience unfortunately I’ll never have - so nice to see someone show how it’s done!
Post WW2, my late father was the instrumentation engineer on the original F-86 project at Muroc Dry Lake (today’s Edwards AFB) back when Check Yeager and the X-1 were trying to break the sound barrier at the other, top secret side, of the base. Talking about walking in front of the engine, my dad told me a story on one of the guys getting sucked into the F-86 and a bunch of his team had to go in and recover his body.
You guys are not idiots, you really have a cool job and you know what really you are doing . Keep up the vids. I really love it . And I really learned a lot ^^ stay safe...
I don't know how you would go about obtaining one or the fuel for it, but I'd die a happy man getting to see you restore/rebuild & do a test run of a J58. One could dream, eh? Your videos are absolutely incredible, Jay!
Awfully sorry, chap, but I get a comment like this every week. And my response is always the same: Could you even tell the difference between a J58 and a J79? Both are large afterburning turbojets that propel aircraft in excess of Mach 2.5. The bypass tubes that make the J58 a ramjet can obviously not be tested during a static test. The J58 is a useless engine that no longer has any purpose. Many J79s are flying today, and many examples of its industrial derivative are also running. If a J79 really isn't enough for you, then you are respectfully asked to leave immediately.
It's more than awsome that a few of our old swedish jetengines ended up in such good hands instead of going to the scrapyard. The swedish dragon ( fpl 35 Draken) conquer a deep blue horizon with the full EBK fireblast roaring like a thunder from the skye ower the deep Nordic forests is a great part of my childhood memories! That's something one neeed to actualy be there and feel with the whjole body, nothing that can ever be described in worlds!
Great video, great memories. We used F86’s at NAWC China Lake for chase and drone targets in the 80’s. We also had a depot level engine rebuild shop to keep those engines in perfect shape, luckily we had a few twin seat trainers that allowed a lucky few of us ground pounders a once in a lifetime flight....
Very interesting and creative for vlog...every jet should have “oh crap button”, but I would’ve thought it’s ejection button...but maybe that’s “aww shit” scenario”...kudos...tnx Agent
Our airline had a certifiable genious as a lead ground instructor. He was a close friend to Sir Frank Whittle. Your videos should be used as jet-indoc as your teaching manner is paramount. I cut my jet teeth on RR Darts, and went up the rungs to the RB 211. Great tutorial.
You're right about being one of the few. Not many of us have the experience, and actually did remove an engine from an aircraft, repair it in the shop, test it on the test cell, reinstall it on the aircraft, and perform the engine run up. I have done that on F-100's and OV-10's Having a 56 year career in Engine tech did give me some advantages LOL
I have started a SAAB J 35 in the cookpit. We diid a engine test on it. Faulty afterburner pump. What power, felt it even if the fighter was secured You felt it.
I simply love seeing aircraft tech... People don't really realize how advanced most of this tech is still today, and nowadays we have way better tech...
The general practice when a fighter jet is undergoing maintenance is to have an egress technician disarm the seat so it can't accidentally be fired on the ground. They used to disconnect the line coming off of the ballistic actuator so the worst that could happen if the ejection handles were pulled is the actuator would fire.
Really good idea using the cockpit to illustrate the start procedure. Also, while contested on a "technical basis", George Welsh (not Chuck Yeager) was actually the 1st person to exceed the speed of sound while flying the XP86 (test bed for the F86). The "technical" matter is that the Bell X1 flight (10/14/1947) was a "certified flight", with all data gathering equipment applied, while Welsh's flight was not certified for "all" regimes. Also, Welsh's flight angle was slightly nose down, while Yeager's flight was in a level attitude. Later, Jackie Cochran was the 1st female pilot to break the sound barrier while flying a "Canadian built" (tada-tada-tada) F86.
Seeing the Sabre cockpit brought back a lot of memories, the most important thing to watch was the. EGT on start up. When I was stationed in Germany an engine tech was doing a full run up a chap decided to go to other side, he passed in front of nose wheel and was sucked up intake ,engine was running at 100% he Didn’t survive. I’ve run up many Sabres, CF 100’s and 104’s plus J79 ‘s in the test cell.
Cool. He's got a wall full of Saab Draken engines. I wonder if he will ever get around to restore them? More importantly, will they be put back into a restored Draken. So amazed that those engines made it so far away out of Sweden into western Canada.
I have a Sabre in my Flight Sim 2004 (still works just fine) that's quite faithful to a real checklist, takes you thru the steps...it's all about the EGT, more important than the tach. Great machinery, thanks for the walk thru on a real piece of history!
I was totally expecting SOMETHING to drop when you hit the drop-all switch. That would have been great! Great video! Keep em coming! Would love to hear that Orenda run and be able to see the throttle actuator moving, maybe some shots from inside the test cell showing the EGT and RPM coming together. (I know there is only so much your allowed to show, maybe haze out everything else)
ya ya ya, but it's not THAT one, geez. (Kidding), I'll find it and have a look. Do you have one of the inner workings of the start cart? I found one you talk about it and show it, but mostly outer stuff. Thanks!
You kidding? This one is a survivor. It's a sin to cut and smash them up for scrap, like tens of thousands of P-38s, P-40s, P-47s, P-51s, P-80s, F-84s, F-86s, F-100s, F-101s, F104s, F-105s, CF-105s ( FFS!), F-4s, B-17s, B-24s, B-29s, B-36s, B-47s, B-49s ( FFS!), B-58s, A-1s, A-4s, A-10s, A-26s; Spitfires, Hurricanes, Lightnings, Canberras, TSR-2s (FFS!), Vulcans, VC-10s, ... I'm sure I've left out hundreds of great aircraft types, and I only went back half way!
He's not really a guard. He likes to watch, and occasionally let people know that he wants something, without explaining exactly what that is. He's management material.
Intersting and educational series. Thank You. Question - was a blast deflector ever considered to be placed outside the building? I notice the manual had one pictured.
That was an awesome video. Looks like that poor Sabre sat outside in the rain and cold for a few years with an open cockpit. Do you have the rest of the aircraft?
Great video, thank you for posting. I live quite close to the former R.A.F Langar in Nottinghamshire, U.K. The Royal Canadian Airforce was based here just after WW2 with the Canadair CL-13B Sabre MK 6, Orenda 14 for power of course.
Throttle lever outboard for ignition & boost pump - if its anything like the A-4, there is a small micro switch that the throttle hits on the outboard slide that activates these. In the A-4 we "came around the horn" at 15% N1 to introduce fuel and start the igniters. If we didnt 'bang' the throttle outboard there was a chance we missed the micro switch, resulting in a wet start.
Dave Souza , you are correct, around the horn.... brings back so many memories doing engine turns. “Go around the horn like a man” was how I was taught, take throttle all the way up and then back to down and start counting for lite off. Oh to be 20 something again
@@AgentJayZ Just to clarify, in the A-4 we were taught NOT to advance the throttle past idle when coming "around the horn" unless we wanted flames to come forward though the compressor and singe our ears. Conversely, if the engine didnt lightoff in 15 seconds (wet start) we had to be darn sure NOT to hit the microswitch when moving the throttle to cutoff. Saw a guy do it once accidentally resulting in a 30' "afterburner"
HeyJay. Yeah obviously the keyboard cowboys have been visiting Canada recently. Trolls will be trolls. Looks like you have a good crew and a tightly run shop. Spool it up!!!!!!!
I’m surprised with the frequency of service, the duration these engines and the company have been around that y’all don’t make pigtail adapters for the engines. I’d assume there is some uniformity at least from the aviation engines. Do you see variance in pin outs from the industrial variants? Are we talking 200 wires or 50?
Each mark number of engine, matched to it's particular mark number of aircraft, is different from the others. We have a plug and play harness adapter for the J79-17, because we see a lot of them. It would not work, for example, with a -19 or a -15. Industrial engines do not have a wiring harness that is anything like an aircraft engine.
Only similar sized engine (turbo shaft) with similar production numbers would be the RR250, but I am always shocked how these don’t fail that often as their parts seem so stressed and the design while a compact package has several point points (peashooter o-ring, number 5 bearing) where if installed wrong or of they fail....it stops...seen a number 5 bearing where the bearing race had come apart and surprisingly they engine got them safely down somehow. PT6 parts seem so much more robust (bearings especially) and seem to pass overhaul inspection more frequently. Hot section repair is somewhat simpler too.
RR 250 started out as a 320 Hp helicopter engine, and has grown to over 750 Hp. It is a hugely successful engine. PT6 started out as a 550 Hp turboprop for light aircraft. It has grown to almost 2000 Hp. It is a monstrously hugely successful engine. The two are at the top of their game, have been for decades, and are not in competition at all. They are both great. They are both awesome, and so far, without peer.
The Draken engines, I'm assuming they are RR Avons licence built by Volvo Flygmotor in Sweden? Do those examples you have there have the Swedish designed afterburner section fitted?
I have had an egt gauge and ammeter sitting around for years that I bought from a garage sale and finially noticed it's from one of these planes. Interesting.
I once read about an insert in the exhaust of a F-86 - like a crescent shape - that somehow vectors the exhaust, and that it could be installed incorrectly, and thus preventing the aircraft from taking off. Heard of it?
Those are for tuning the thrust by making small changes to the nozzle outlet diameter. They are called mice by some, and they do not vector thrust. I installed one this morning.
In agreement with the others, thank you, always very interesting. I wish you could have the trolls in your shop for a day, or two, so they could demonstrate their extensive knowledge of the industry. Now that would be a hoot.
Hi Jay :) Thanks for yet another awsome video :) Just one (proberbly stupid and already asked question) but why do you not make a "standard" wireing loom for connection to the original pins ? Would you not save any time on hooking it up with that? Or is the wiring different on the engines?
Those people should not call you an idiot for walking near the intake, but safety is not to be taken lightly. There are a lot of things that you can do 1,000 times and be lulled into a false sense of safety. This does not just apply to jet engines, it's universal in the workplave.
Advanced analysis has repeatedy shown that "those people" who call me an idiot are not involved in the industry. You might call them know-nothing know-it-alls. Yeah, I would.
Yes. You'll save money by finding your own instead of buying one from a dealer. You need to become familiar with the aviation aftermarket. The scrap industry will be a good source if you aren't going to fly it. S&S Turbines may be able to help you find one.
Hi Jay. In the 90’s I lived in Edmonton. There was a farm in between Spruce Grove and Stoney Plain on HWY 16X. Now on that farm was an old Quonset and behind that Quonset was what I believe was one of those jets! I so wish I had went and talked with that fella as the farm is gone and a tractor sales shop sits in its place. Do you happen to know anything about that plane?
While running the HI-BAY (Test Cell0 For the AGM-28B Hound Dog W/ the J52 P3 we always installed an Inlet FOD Screan. One time I plaved my gloved hand on the screen at the edge of the Inlet.(Spike System) at Max Military Just to see what kind of Suction it had It was signifant but not overwelming. The J52 was also used in : AGM-28B Hound Dog Dassault Super Mystere Douglas A-4 Skyhawk Grumman A-6 Intruder Lockheed Martin A-4AR Fightinghawk Northrop Grumman EA-6B Prowler
Was there ever a jet engine that had vacuum tube (hybrid?) fuel control? I seem to remember reading about it and thinking that rough landings would break the filaments. ..or am I thinking radar?

The only reason I come back is to wait for mention of the Iroquois :D WHATS HAPPENING WITH THE IROQUOIS! ...Really looking forward to updates on that beauty.
Why are all the temperatures referred to in Fahrenheit? Is it because the engine was designed in the USA? I live in the USA, but fly French aircraft, and I am used to seeing all the engine temperatures in Celsius. Quite strange.
Hello I’m learning a lot thanks to your channel. please I have a question what will happen if instead of kerosene (fuel) I had rather gasoline (vehicles) in a turbojet. Thank you
Gasoline is much more dangerous and more expensive than jet fuel. Fuel pumps and fuel controls are lubricated by fuel, so they will not last as long when using gasoline. Otherwise the engine will run fine.
hello thank you for this clarification, I am a young engineer and I aim to design planes (fuselage and turbojet) and I would like to know if you can help me with advice or documentation on the subject thank you and good day.
What about the higher sulphur (and perhaps carbon, too) contents in diesel oil compared to Jet A1, that is more refined and pure? Corrosion/deposit problems in the long run?...
master, starter ingition wait for spoon then move throttle to boost pump and to idle to continue start if exceeds 700c pull back to cut off hold starter and retry.
Very cool 👍😎 Jay. I would love to sit in that cockpit and dream of flying an F-86 D. My favorite 1950's jet. I do pray Your F-86 gets put back to flying condition.
so it should look a bit like this (hopefully I've not forgotten anything, watched it several times..): - starty (start-cart) ON - starter ON (max 45s) - 500rpm: ignition ON - 700rpm: throttle Position START - --- ignition -- - ignition OFF - 1800rpm: starter OFF --> at which point do you advance throttle from "start" to "idle"? I hope this isn't a stupid question, I can't find if there is a "start"+"idle" or just an idle, just a start or if they are both the same. As you don't describe that you would have to advance from "start" to "idle" in the runup, I guess "start" = "idle"?
I still remember starting my first jet engine way back in 1997.
I was a 18yr old 3rd year apprentice and my boss entrusted me to fire up two GE CF-6-80C2's on a Qantas Boeing 767-300.

Hiller Aviation Museum in San Carlos had an A-4 avail to sit in as of 20 years ago. They also had the nose of the SST, but I heard that one was shipped up north recently.
People who call u idiots are just idiots themselves being jealous of your work! Fine videos, I learn a lot from them while studying to become an aircraft technician!
glad that you had the fun of getting in a Sabre and running the engine! I spent some time as an avionics tech on A-4 Skyhawks, and had a license to run the engine. Definitely a fun thing to do... until the time my ground crew gave me the fire sign! Turned out to not be a fire, but sure was a bit of excitement that I didn't need. :-)
Thanks Jay great distraction given the stress in the world at the moment. Stating a gas turbine in the cockpit of a fighter is an experience unfortunately I’ll never have - so nice to see someone show how it’s done!
I need all that engineering goodness, don’t hold back! Plenty of time on hand(!). Happy 😊 Sunday..(!)
So cool, stay safe! love watching all you do!
Post WW2, my late father was the instrumentation engineer on the original F-86 project at Muroc Dry Lake (today’s Edwards AFB) back when Check Yeager and the X-1 were trying to break the sound barrier at the other, top secret side, of the base. Talking about walking in front of the engine, my dad told me a story on one of the guys getting sucked into the F-86 and a bunch of his team had to go in and recover his body.
That's crazy, great story
You guys are not idiots, you really have a cool job and you know what really you are doing . Keep up the vids. I really love it . And I really learned a lot ^^ stay safe...
"I love to be corrected by ignorant people" ... don't we all. It helps to maintain our humility 😂
Keep up the good work. Stay well and stay safe.
Manuals full of informational goodness
I don't know how you would go about obtaining one or the fuel for it, but I'd die a happy man getting to see you restore/rebuild & do a test run of a J58.
One could dream, eh?
Your videos are absolutely incredible, Jay!
Awfully sorry, chap, but I get a comment like this every week. And my response is always the same: Could you even tell the difference between a J58 and a J79?
Both are large afterburning turbojets that propel aircraft in excess of Mach 2.5.
The bypass tubes that make the J58 a ramjet can obviously not be tested during a static test.
The J58 is a useless engine that no longer has any purpose.
Many J79s are flying today, and many examples of its industrial derivative are also running.
If a J79 really isn't enough for you, then you are respectfully asked to leave immediately.
It's more than awsome that a few of our old swedish jetengines ended up in such good hands instead of going to the scrapyard.
The swedish dragon ( fpl 35 Draken) conquer a deep blue horizon with the full EBK fireblast roaring like a thunder from the skye ower the deep Nordic forests is a great part of my childhood memories! That's something one neeed to actualy be there and feel with the whjole body, nothing that can ever be described in worlds!
If someone need the original fuel level messuring devices i think i still hawe a few left... ha ha
Great video, great memories. We used F86’s at NAWC China Lake for chase and drone targets in the 80’s. We also had a depot level engine rebuild shop to keep those engines in perfect shape, luckily we had a few twin seat trainers that allowed a lucky few of us ground pounders a once in a lifetime flight....
It is extremely kind of you to share this information and take the time and trouble to
do it.
Very interesting and creative for vlog...every jet should have “oh crap button”, but I would’ve thought it’s ejection button...but maybe that’s “aww shit” scenario”...kudos...tnx Agent
Nice video, my Dad worked with the Golden hawks for a few months to fill in for sick leave. he did spends time as navigator in the CF100's and Argus
Our airline had a certifiable genious as a lead ground instructor. He was a close friend to Sir Frank Whittle. Your videos should be used as jet-indoc as your teaching manner is paramount. I cut my jet teeth on RR Darts, and went up the rungs to the RB 211. Great tutorial.
You're right about being one of the few. Not many of us have the experience, and actually did remove an engine from an aircraft, repair it in the shop, test it on the test cell, reinstall it on the aircraft, and perform the engine run up. I have done that on F-100's and OV-10's Having a 56 year career in Engine tech did give me some advantages LOL
I have started a SAAB J 35 in the cookpit. We diid a engine test on it. Faulty afterburner pump. What power, felt it even if the fighter was secured You felt it.
I simply love seeing aircraft tech... People don't really realize how advanced most of this tech is still today, and nowadays we have way better tech...
I was waiting for the ejector seat to go off !
In this seat, it's not a joke, and I would rather not die today...
The general practice when a fighter jet is undergoing maintenance is to have an egress technician disarm the seat so it can't accidentally be fired on the ground. They used to disconnect the line coming off of the ballistic actuator so the worst that could happen if the ejection handles were pulled is the actuator would fire.
Yes, I'm fairly sure the charges have been removed from this derelict, but do I want to bet my life on it?
@@AgentJayZ No. Ejection seats can be dangerous. You don't want to end up splattered on the roof of the hanger.
Agent jay zeeeeeeeeeeeeeee.!
very cool video sir, i was born in ole fsj ive herd of yah didnt know you were on youtube, awesome. thanks for the video, cheers!
"Again, for the hundredth time, thank you..." 😂
You’re a highly informative person. Thanks very much for making these videos! 👍
Ohhh looks like a full fuselage in the background, restoration project in sight/dreams ?
Really good idea using the cockpit to illustrate the start procedure. Also, while contested on a "technical basis", George Welsh (not Chuck Yeager) was actually the 1st person to exceed the speed of sound while flying the XP86 (test bed for the F86). The "technical" matter is that the Bell X1 flight (10/14/1947) was a "certified flight", with all data gathering equipment applied, while Welsh's flight was not certified for "all" regimes. Also, Welsh's flight angle was slightly nose down, while Yeager's flight was in a level attitude. Later, Jackie Cochran was the 1st female pilot to break the sound barrier while flying a "Canadian built" (tada-tada-tada) F86.
From videos I've seen of interviews with Mr. Yeager, the X-1 flew an arc and went supersonic in a long shallow dive. The first time anyway.
,,, I'm not so sure that G. De Havilland wasn't the first to break the barrier, but didn't survive the encounter..
@@rolandtamaccio3285 Now that's a really good technical point.
Seeing the Sabre cockpit brought back a lot of memories, the most important thing to watch was the. EGT on start up. When I was stationed in Germany an engine tech was doing a full run up a chap decided to go to other side, he passed in front of nose wheel and was sucked up intake ,engine was running at 100% he Didn’t survive. I’ve run up many Sabres, CF 100’s and 104’s plus J79 ‘s in the test cell.
Thank you for all the work in creating these videos! Totally enjoy them!
Cool. He's got a wall full of Saab Draken engines. I wonder if he will ever get around to restore them? More importantly, will they be put back into a restored Draken. So amazed that those engines made it so far away out of Sweden into western Canada.
Probably belong to Danish Draken's.
A bunch of retired Danish Draken's made it to the National Test Pilot School in Mojave but is scrapped by now.
I have a Sabre in my Flight Sim 2004 (still works just fine) that's quite faithful to a real checklist, takes you thru the steps...it's all about the EGT, more important than the tach. Great machinery, thanks for the walk thru on a real piece of history!
I was totally expecting SOMETHING to drop when you hit the drop-all switch. That would have been great!
Great video! Keep em coming! Would love to hear that Orenda run and be able to see the throttle actuator moving, maybe some shots from inside the test cell showing the EGT and RPM coming together. (I know there is only so much your allowed to show, maybe haze out everything else)
A couple weeks ago I showed all of that with an Orenda 14 test.
ya ya ya, but it's not THAT one, geez. (Kidding), I'll find it and have a look. Do you have one of the inner workings of the start cart? I found one you talk about it and show it, but mostly outer stuff. Thanks!
That's a former SAAF F-86 Sabre. Brings back nostalgic memories.
It's a sin to let all the old planes turn to crap like that. Great video, thanks.
You kidding? This one is a survivor. It's a sin to cut and smash them up for scrap, like tens of thousands of P-38s, P-40s, P-47s, P-51s, P-80s, F-84s, F-86s, F-100s, F-101s, F104s, F-105s, CF-105s ( FFS!), F-4s, B-17s, B-24s, B-29s, B-36s, B-47s, B-49s ( FFS!), B-58s, A-1s, A-4s, A-10s, A-26s; Spitfires, Hurricanes, Lightnings, Canberras, TSR-2s (FFS!), Vulcans, VC-10s, ...
I'm sure I've left out hundreds of great aircraft types, and I only went back half way!
Is the French Bulldog particularly suited to guarding jet engine maintenance and test facilities?
He's not really a guard. He likes to watch, and occasionally let people know that he wants something, without explaining exactly what that is. He's management material.
@@AgentJayZ Brilliantly funny!!!! :)))))
Spent many years running and taxing F101 twin J57 truly a memorable experience
Brilliant insight, thank you.
Intersting and educational series. Thank You.
Question - was a blast deflector ever considered to be placed outside the building? I notice the manual had one pictured.
Could you imagine flying in one of those?!
Any jet at that. That's one of the ultimate thrills/accomplishments. What a ride!
I believe that "MIL" stands for "Military Power" setting.
I do believe you are right.
That was an awesome video. Looks like that poor Sabre sat outside in the rain and cold for a few years with an open cockpit. Do you have the rest of the aircraft?
Axial flow mate, love from Australia.
Awsome video Jay! I like the hands-on in the sabre.
hey man. awesome job. Many thanks.
Great video, thank you for posting. I live quite close to the former R.A.F Langar in Nottinghamshire, U.K. The Royal Canadian Airforce was based here just after WW2 with the Canadair CL-13B Sabre MK 6, Orenda 14 for power of course.
Throttle lever outboard for ignition & boost pump - if its anything like the A-4, there is a small micro switch that the throttle hits on the outboard slide that activates these. In the A-4 we "came around the horn" at 15% N1 to introduce fuel and start the igniters. If we didnt 'bang' the throttle outboard there was a chance we missed the micro switch, resulting in a wet start.
Dave Souza , you are correct, around the horn.... brings back so many memories doing engine turns. “Go around the horn like a man” was how I was taught, take throttle all the way up and then back to down and start counting for lite off. Oh to be 20 something again
Jeff D.: that is not how you do it. That's how you get fired.
Oh, never mind me.
I'm just a guy who starts and test jet engines.
I don't know nothin'!
@@AgentJayZ Just to clarify, in the A-4 we were taught NOT to advance the throttle past idle when coming "around the horn" unless we wanted flames to come forward though the compressor and singe our ears. Conversely, if the engine didnt lightoff in 15 seconds (wet start) we had to be darn sure NOT to hit the microswitch when moving the throttle to cutoff. Saw a guy do it once accidentally resulting in a 30' "afterburner"
HeyJay. Yeah obviously the keyboard cowboys have been visiting Canada recently. Trolls will be trolls. Looks like you have a good crew and a tightly run shop. Spool it up!!!!!!!
I would love to work for you guys, there is just so much knowledge in those halls I would have killed to have access to! Brilliant content.
Ohhhh, do I remember holding the throttle controls, either seat, when performing maintenance on the ol' beloved F-4e/g!
A very welcome flying related diversion.
'your gonna get sucked into the injet'
dude literally works on jet engines for a living you really dont think he knows how they work xD
Would love to see this test in person, hope you will share it with us!
I’m surprised with the frequency of service, the duration these engines and the company have been around that y’all don’t make pigtail adapters for the engines.
I’d assume there is some uniformity at least from the aviation engines. Do you see variance in pin outs from the industrial variants? Are we talking 200 wires or 50?
Each mark number of engine, matched to it's particular mark number of aircraft, is different from the others.
We have a plug and play harness adapter for the J79-17, because we see a lot of them. It would not work, for example, with a -19 or a -15.
Industrial engines do not have a wiring harness that is anything like an aircraft engine.
Canada builds the best turbine engines easily ...
from a PW jockey 👍
I once described the PT-6 as the small block Chevy of turbine engines... but it's even better than that.
I has no competition.
Only similar sized engine (turbo shaft) with similar production numbers would be the RR250, but I am always shocked how these don’t fail that often as their parts seem so stressed and the design while a compact package has several point points (peashooter o-ring, number 5 bearing) where if installed wrong or of they fail....it stops...seen a number 5 bearing where the bearing race had come apart and surprisingly they engine got them safely down somehow. PT6 parts seem so much more robust (bearings especially) and seem to pass overhaul inspection more frequently. Hot section repair is somewhat simpler too.
RR 250 started out as a 320 Hp helicopter engine, and has grown to over 750 Hp. It is a hugely successful engine.
PT6 started out as a 550 Hp turboprop for light aircraft. It has grown to almost 2000 Hp. It is a monstrously hugely successful engine.
The two are at the top of their game, have been for decades, and are not in competition at all.
They are both great. They are both awesome, and so far, without peer.
The Draken engines, I'm assuming they are RR Avons licence built by Volvo Flygmotor in Sweden? Do those examples you have there have the Swedish designed afterburner section fitted?
Thank you for entertaining me.
OK thanks very much...l sure do like those jet boat you work on up there...That's awesome..!
The old jet is too cool i bet the old dials have radium paint. Really radioactive. Thanks for the vid
Does the manual say anything about service intervals or engine life time depending on use of MIL vs. only nominal?
Hi sir thanks for sharing your knoledge to us. Can explain how compressor blade turn?im jus curious.
I have had an egt gauge and ammeter sitting around for years that I bought from a garage sale and finially noticed it's from one of these planes. Interesting.
I once read about an insert in the exhaust of a F-86 - like a crescent shape - that somehow vectors the exhaust, and that it could be installed incorrectly, and thus preventing the aircraft from taking off. Heard of it?
Those are for tuning the thrust by making small changes to the nozzle outlet diameter.
They are called mice by some, and they do not vector thrust.
I installed one this morning.
@@AgentJayZ I know them as 'trimmers'.
I've been watching your channel for a while, and I had no idea you are in Ft St John, only a couple of hours from me! Greetings neighbor!
5:26 If I'm not mistaken, I believe I see a package of extensions from Princess Auto near your left shoulder.
In agreement with the others, thank you, always very interesting. I wish you could have the trolls in your shop for a day, or two, so they could demonstrate their extensive knowledge of the industry. Now that would be a hoot.
@Kelley Simonds - I don't think that experiment would last more than about 5 minutes. Jay has a pretty low tolerance for clueless idiots.
Hi Jay :) Thanks for yet another awsome video :) Just one (proberbly stupid and already asked question) but why do you not make a "standard" wireing loom for connection to the original pins ? Would you not save any time on hooking it up with that? Or is the wiring different on the engines?
What a cool job! :)
GBY AJZ for the jolly
"So if you want your high speed roast beef being ripped off your face this is where you stand" HAHAhahahaha
Those people should not call you an idiot for walking near the intake, but safety is not to be taken lightly. There are a lot of things that you can do 1,000 times and be lulled into a false sense of safety. This does not just apply to jet engines, it's universal in the workplave.
Advanced analysis has repeatedy shown that "those people" who call me an idiot are not involved in the industry.
You might call them know-nothing know-it-alls.
Yeah, I would.
One question or two: Have You ever overhauled a GE J 85? And where do I get good engines of this type and what do they cost in average?
Yes. You'll save money by finding your own instead of buying one from a dealer. You need to become familiar with the aviation aftermarket. The scrap industry will be a good source if you aren't going to fly it.
S&S Turbines may be able to help you find one.
@@AgentJayZ thank You
Zorn, if you have to ask "how much do they cost", then you can't afford it.
Very cool Video!! Interesting Saab Draken engines.. Did Canada had Drakens in service? Engine is license built Rolls Royce?
We did not. People still fly the Draken.
i was test cell qual'ed and was getting checked out in the cockpit to run the j79 before i went to i level maintance in the navy f4 forever
Nothing better than feeling better, you've been told.
Hi Jay. In the 90’s I lived in Edmonton. There was a farm in between Spruce Grove and Stoney Plain on HWY 16X. Now on that farm was an old Quonset and behind that Quonset was what I believe was one of those jets! I so wish I had went and talked with that fella as the farm is gone and a tractor sales shop sits in its place. Do you happen to know anything about that plane?
While running the HI-BAY (Test Cell0 For the AGM-28B Hound Dog W/ the J52 P3 we always installed an Inlet FOD Screan. One time I plaved my gloved hand on the screen at the edge of the Inlet.(Spike System) at Max Military Just to see what kind of Suction it had It was signifant but not overwelming.

Northrop Grumman EA-6B Prowler
Was there ever a jet engine that had vacuum tube (hybrid?) fuel control? I seem to remember reading about it and thinking that rough landings would break the filaments. ..or am I thinking radar?
There must have been. Back when these were combat jets, "electronic" meant tubes...
Transistors weren't invented until 1957, and the F-86 pre-dates that by at least 5 years.
I don't know how but there's quite a lot of vacuum tubes in early aircraft electronics and they survived quite well.

...Really looking forward to updates on that beauty.
Why are all the temperatures referred to in Fahrenheit? Is it because the engine was designed in the USA? I live in the USA, but fly French aircraft, and I am used to seeing all the engine temperatures in Celsius. Quite strange.
depends on the manufacturer. some are in metric, some are imperials
The Douglas A-4 (American) designed in the late 50s used Celcius.

Hello I’m learning a lot thanks to your channel.
please I have a question what will happen if instead of kerosene (fuel) I had rather gasoline (vehicles) in a turbojet.
Thank you
Gasoline is much more dangerous and more expensive than jet fuel. Fuel pumps and fuel controls are lubricated by fuel, so they will not last as long when using gasoline. Otherwise the engine will run fine.
hello thank you for this clarification, I am a young engineer and I aim to design planes (fuselage and turbojet) and I would like to know if you can help me with advice or documentation on the subject thank you and good day.
We have run Allison C20 turbine in a 500D on diesel after starting on Jet A1 runs fine no problems ,refuel on diesel with engine running
What about the higher sulphur (and perhaps carbon, too) contents in diesel oil compared to Jet A1, that is more refined and pure? Corrosion/deposit problems in the long run?...
@@Elhombresombra perform a turbine flush

Very cool video. Interested to know much run time do you need to test an Engine?
An hour if things go well.
so it should look a bit like this (hopefully I've not forgotten anything, watched it several times..):
- starty (start-cart) ON
- starter ON (max 45s)
- 500rpm: ignition ON
- 700rpm: throttle Position START
- --- ignition --
- ignition OFF
- 1800rpm: starter OFF
--> at which point do you advance throttle from "start" to "idle"?
I hope this isn't a stupid question, I can't find if there is a "start"+"idle" or just an idle, just a start or if they are both the same.
As you don't describe that you would have to advance from "start" to "idle" in the runup, I guess "start" = "idle"?
Yes. When the pointer is in the idle box, the engine should start and rise to idle rpm without burning up. ...should...
COOL. Hello from AZ.
