I so share that enthusiasm for fresh metal. Especially fresh metal that has purgatoried for decades awaiting its moment to "shine". I get the same feeling from guitars, amps, and other vintage musical devices as well as firearms. Thanks for sharing the moment AJZ!
Next time I fly, I am going to imagine that the previous engine overhauling was carried out by a person who is as thrilled with the sheer joy of his or her job as you are!
other youtubers would've made this into a 4 part series - OPENING OLD GENERAL ELECTRIC CAN FROM 1954 - YOU WON'T BELIEVE WHAT'S INSIDE
It seems we now have a new subgenre, the Uncanning Video.
Bar NONE, the best "unboxing" vid I've ever watched.
Did you watch the bonus footage?
Indeed. :-D
I understand his happiness. To a person who builds engines, no matter what kind, a set of brand new old stock parts is a thing of beauty!
That's some resourceful customer to be able to get their hands on a full set of new blades
Either that, and/or just got super lucky with a shop cleanup/closure/surplus auction. Can't keep but wonder: there must be more where these came from. :o
I don't comment on your videos but this was amazing. I work in the overhaul industry but never ever have seen turbine blades that old and in mint condition. Thanks J Z for sharing that.
This is engineering porn. You have made many a turbine blade and their appreciators happy.
I really appreciate comments like yours.
I have to deal with haters trying to damage my channel every single day.
Thanks for watching, and welcome to Jet City!
I haven't seen any one explaining in detail about turbine blades like him
Excellent work sir,
So this is what a blade looks like in close look
Hats off for detail explanation
I am from India
i never thought id feel feelings for a turbojet blade
you go buddy, you go
That is one happy blade. I hope I look that good at 65.
I totally 'get' the feeling of handling 60 year old NOS parts. It is rare that anyone gets to reveal 99 of them in one setting. Congrats. thanks for sharing, regards/greg.
I've been in the aerospace MRO/OEM industry for almost 5 years now and have only focused on understanding the requirements of individual components of turbojet and turbofan engines. I've developed dozens of repair processes and reviewed thousands (probably hundreds of thousands) of pages of repair manuals and component drawings learning vast amounts of information about individual parts that make up these engines, but until I started watching your videos, I did not fully understand the overall function and purpose of many of these components. You have broadened my understanding of the engines I help service and have greatly increased my enthusiasm I have for the work I do. It''s amazing how differently I look at some of my projects now that I have a solid understanding of how they will ultimately be utilized. Thank you for all your great content and I hope you continue to provide the same high-quality information for years to come!
Thanks! Welcome to Jet City!
Those new blades are museum-worthy pieces of history. Seeing them gives me chills. It's like opening one of those WW2 MRE rations with still edible candy in it.
You are truly touched with the nack, and i have never been so moved by a TH-cam video. How utterly pleasing! Thanks so much for sharing.
This comes from a good friend retired RCAF. Best regards from VI (yes that one) A.
had just over 300 hrs on the F86E model powered by the J47. My two forced landing crashes were in F86Es due to engine failures. The first one resulted from a failure of the barometric fuel control unit which adjusted the fuel/air mixture with changes in altitude. My engine hung up at 80% power while I was on letdown to base - Zweibrucken in Germany, and it flamed out on final approach which put the aircraft through the airfield fence and approach lights.
The second one occurred five weeks later when I was ferrying an F86E to Turkey. The engine seized up with a loud bang at 33,000 ft over the Mediterranean, and I force landed wheels up on a partially built airfield on the Italian coast. The accident investigation showed that one of the engine main bearings had seized due to oil starvation. Needless to say, I was very happy to start flying the Orenda powered birds built by Canadair shortly thereafter.
Your enthusiasm is infectious! I was on the edge of my seat when you cut open the can!
💐 Thanks jay for sharing your amazing knowledge with us through your videos. I am not a Aerospace engineer, but still I can able to explain someone about how does Jet engine's are works and how thrust generated because of you. I always love to watch your video's and try to understand the principal of working and I gain my knowledge everyday. As you know learning is never ending process. Any way thanks for the video.
Your excitement is contagious, its wonderful. Your videos are really the very best, thanks for sharing your joy.
8:04 The damage to the shroud was caused by the blade separation. It contained the debris and saved the plane from more severe damage.
Watched a video on the development of jet engines this past week. Ten years after commercial production they had already reached the level of development that this engine still is used like this. Just some amazing technology.
It is simply amazing to have a new set of blades for that model engine. Such a rare thing to see or encounter. Great video sir. Thank you.
I don't understand why I was so excited to watch you unpack such old beautiful parts.
I watched this from start to finish with great fascination... Love these videos... keep them coming.
Definitely sensing the glee on this side of the screen. Ha! What a treat opening those new-old stock parts! Wow! :) Christmas came early for you. :) Can't wait to see them coated.
Edit: Yeah i'd probably also be worried about asbestos. Since it was the wonder material of yore. They used it for everything. :/
What you are showing is pure gold to an aviation enthusiast. Thank you!
EXCELLENT camera setup on the shot where you're tapping out the roll pin. Very clear what was happening.
First of all, I fully admit that I lack sufficient motivation, time, and funds to become a gas generator mechanic. That being said, I would thoroughly enjoy having the opportunity to be in the shop, pestering everyone & getting in the way, for the complete process of an engine restoration - from initial receiving to final shipment of finished project.
Thanks again for giving us all a glimpse of the work you do!
Your videos are absolutly wonderful. I learned a lot, and it continues with every single video. Of course I won't ever have your level of expertise ! But that way I can feel a bit closer to my grand dad who used to work on an aeronautic base. Thank you, really, for all the beautiful things you teach us !
Super interesting video. Love hearing about the evolution of these engines. Thank you.
What an engineer. (And what a happy turbine blade)......Thanks for taking the time. John UK.
Your video's are very informative. I work for a company that could have very well made those blades back in the 50's. Watching your videos helps explain the reasons behind some of the grinds that I have done with vanes and blades.
I like to see people doing their job with passion and excitement even after years.
love the ringing sound when you made its "dream" come true!
Great thanks for the education. I watched those engines powering F86's and FJ-1 Navy variant as a young man at Point Mugu where my father worked at the time and other places since then. I watch all your videos... thanks again.
You, sir, are super entertaining. I thoroughly enjoy your passion for your work. And you explain things in a very clear, down-to-earth way. Would that my professors in college had been as effective as you are in dialing out ambiguity and complexity. Had that been the case, I have no doubt that I would be more effective in my chosen profession.
Sweet... My father had a complete set of operations/maintenance manuals for the J47 that went into the F-86D (afterburning). I basically learned to read using these manuals. The color illustrations of the laid the foundation for my ability to read engineering diagrams. Alas they are long gone...
Thank you for the video...
Dang. I'm offering you thousands for them...
The finest we ever get to see are "first copies" in B&W of course, and they are very rare. Mostly copies of copies of copies...
Wish I still had them I'd give them to you. They had a very odd leather/plastic pebbled finish 3 ring binder. Alas a leak in the old storage building at my mothers house in Vermont killed those and many other manuals for 7-8 other airframes my father worked on in the 50's and 60's.
Thanks for the video. I have been involved in Turbine blade coated In Gadolinium for Neutron NDT. Even today the design of ‘Blades’ have not changed its shape and design. We have seen smallest, smaller, small, medium, large and larger ones, brand new blades to
Ones that was removed from fighter jets. Happy to see your video. Cheers.
Love watching someone who clearly loves the job they are doing :)
That was so exciting even for me a total novice!!!!!! Love it! Keep us posted!
Thanks for the video. Very nice explanation and a lot of information as always. Apreciate your work and effort as non jet guy, only wrenching on GA under supervision. Always learning new things from you, thanks. Sorry about language, non native speaker.
Watched this immediately after the video showing the unpacking of 96 ceramic blades and one of your workmates tap two together making them ring. You were mortified. Your description here then of how a tiny nick might start a destruction process that might take years immediately brought to mind that ringing of the blades.
How cool, I was 9 years old when those blades were packed.Thank you very much.
1953 7 years before I was born.
Absolutely fascinating! Your enthusiasm and energy are contagious. :)
Paradise.....New Old Parts
Helped clear a friends grandads work shop we found a load of genuine BSA motorcycle parts from the 1950s most were very rare. All were boxed, wrapped and in prefect condition. I was like a pig in poop.
EXTREMELY entertaining , best un'canning i've ever seen
Ooey gooey rich and chewy, that come straight the specifications manual.
You are awesome, me and a friend of mine talk everytime about your videos, best regards from Spain.
Those blades are just insane, for not talking about the cans holy shit! I wonder where the hell the customer got them, they can't have come cheap.
I must have handy guy empathy. 1/2 the video I was stressed and concerned, where were you going to find those blades !!! I was 6 months old when they wrapped those babies ! Wish I aged that well. Congratulations thank you. Really enjoyed that.
love it. idk how anyone can dislike your videos
I love this video... today I understood The importance of accuracy and precession.. which directly effect the safety and risk of the flying machine... thank you Ajent .I m your big fan ..😊😊
You Sir, are a sensational explainer. If only my Physics teacher were as good as you, I would be teaching quantum computing and superposition (one electron in two places at the same time) now. Thankyou so much.
I'm building a 3d turbojet engine in Blender so real thanks for going into so much detail.
this guy is incredible. some one who really loves quality
Very cool! Love those 50's wrapped blades!
21:18 "Nice hiss"
Steve would eat one of those blades.
I. Am. So. Excited. -_-
This IS fantastic. I was born in ‘53, which is an eon ago. K-rats, turbine blades, me, still fresh after all these years.
Fantastic. Take advantage of the roll pin's brittle nature. We used roll pins as the break point in the doors on city buses, cheaper than links. I didn't know that the blades can move as they do. Thanks for the video. Next time I'll check out the notes more carefully.
NOS parts are the best in the sense of nostalgia at the minimum and possibly even replacement. Pretty crazy to think the guys that mfg’d the parts on manual machines and the guys that bundled them up are most likely long gone by now. I love the cool old sheit from before the CNC & cad software era.
Can you imagine how long normal cars would last if auto mechanics had this level of expertise?
Then car manufacturers will run out of biz after 5 years since no one will buy new cars...kekekekee
Fun video Jay! Those turbine blades were made the month after I was born. Dang that makes me feel old!
They are bright and shiny, brand new. It's all in the attitude!
Check the info section for a link to bonus views of the NOS blades...
I don't know if I tagged you in a post where I asked this question. Are Turbine blades considered somewhat consumable like pistons are in an automotive engine? I know they're expensive and generally saved and normally aren't replaced.
In the same way piston are consumable, so are turbine blades.
They are replaceable, but can last a long time under normal operating conditions.
This one sparks Joy.
I wish I looked that good after being in a can since 1953. I've been in this body since 1950 and don't shine much at all.....LOL. Thanks for the explanation and for sharing your job.
Fascinating watching you open those cans of history
I loved it when you said centuries, I was trying to picture an 18th century jet.
Blades in a can! That is classical rear opportunity to handle such a historical piece.
Such a satisfying video AgentJayZ! My volleyball buddy owns a turbine company at LAX and it's so much fun to talk shop with him about engines and I understand everything he does from all your videos. He's basically you guys & gals at Jet City but in SoCal LAX. Thank you! I should send you a Hermosa Beach flag. It'll be small, if we have one, hmm. Keep up the great work!
A treasure from past. Amazing. Thanks only I got.
Thanks mate, really taught us a lot......
Ah, JEIM memories! I trained on the versions used in B-52 at Chanute AFB.
Thanks a lot for excessive and useful information
Really we learn from you a golden information.
Incredible rhymes.
Thanks for sharing the "time capsule". You should see if the customer would let you do a giveaway on one of the cans with the labels that the blades came in. I think that would be cool to have.
cans already recycled. Saved the few good labels. Want a copy? Send an envelope.
I'm giddy with excitement and the first can isn't even open yet!!! :) Love this episode!!! :)
The broken blades would make a sweet hand shovel for metal detecting and with the milled dove tail would make them interchangeable for different shapes
16:30 Our technicians are trained to do the same thing. For instance, there are 55 threaded holes around the perimeter of a PW4000 #2 bearing support, so when reinstalling Helicoils, the operator must break off, collect, and count all 55 tangs to verify that no foreign material is left in the component.
Wit very video I watch I say "Man, this channel is so cool!".
Now that is some special new old stock.
You've seen all 3 Sabre engines! The Aussies also built a version, the CAC Sabre, which had an Avon in it.
Like surgery, make sure all the tools and other pieces are accounted for so that they are not left in the patient.
Thanks for showing this!
Great video agent jay z.wow those blade's.amazing.😀
Well I enjoyed every bit of it
For a jet engineer these wonderful turbine blades from 1953 are probably the same thing as a rare bottle of precious 1953 Bordeaux for a wine connoisseur. The best job in the world is always a job you really love. And here it shows.
BTW: another method getting those pins out is by using a slide hammer. But since these old pins might show signs of fatigue, using new ones is probably the correct way.
Probably?
Thanks for the first comment.
Your btw addition is completely erroneous. The only way to remove the pins is the way they were designed to be removed.
I see you even thinking about trying anything else, and you'll be escorted to the the curb for your richly deserved permanent vacation.
So cool you get to keep the F-86 flying. You lucky guy! Well deserved flight I watched recently. Great to see a Canadian and USAF Sabre in the air together. Have to say I love the f100 Super Sabre(who doesn’t?!)...Collings foundation fly one? Mmm. J57? Have you worked on one or are they “super rare”? I’ll troll through and see. Noted the J79 features so maybe and old question....It must cost a fortune to maintain airworthy warbirds. cheaper to own your own Gulfstream maybe😂. Amazes me how complex a thing can be so reliable. I see HMAS Canberra has LM2500...have new appreciation thanks to you. Love the detail.
engines are amazing thanks so much ,I love jet engines since I was a kid!!!!!!!!!!!!!!!!!!!!!!!you are a genious man!!!!!!!!!!!!!! real jouls in there!!!!!!!!!!!!!
Cool.
Nice job once again.
Best unboxing vid ever.
Oh...? Did you read the info section...?
LOL. Love watching your videos. Life long dream fulfilled 🎉
Very cool cans of NOS parts!! Quick question about the broken blade, why is the part that was slowly cracking cleaner looking than the back end that just broke and it being rusty looking? Not that I doubt how it cracked, you can see the other blades with the cracks, but normally wouldn't the oldest part of a crack be rusty and the fresh crack cleaner looking?
that was just awesome, thanks
Turbojets are people too! Cool vid(s), thanks for posting :)
Would never thought the roll pins for holding on these blades was this soft, interesting.
several overhauls in just 300 hours, that sounds like some very expensive fun
Second favorite TH-cam script. Lol. Between you and Alec Steele. Maybe it’s a tie.
Merry Christmas AgentJayZ
Man, you're like a kid on Christmas morning opening those cans.
What amazes me about that sheared turbine blade (which I definitely thought was long term heat fatigue with a sudden fod impact that did it in) was that a lot of those blade were probably in at least a similar state and one pebble or whatnot lodged itself into the shroud and wreaked havoc.
Man, you nailed the time capsule analogy! What a treat!! For car people, that would be like opening a barn door and finding a Mercury in pristine condition beneath a hermetically sealed tarp, defying a tremendous number of odds in surviving history. The last time those blades saw the light of day... Actually, I'm just going to have a nice think on that.
The blade was broken, not sheared. There was no FOD. There were thermal cracks on the leading edge, and they grew slowly due to fatigue and thermal stress. Eventually, they would all break like this one, but the fun stops after the first blade breaks.
@@AgentJayZ I understood you, Master Yoda. I was theorizing before you explained it in the video, though yes, I theorized incorrectly on the fod. My other theory, not that it really matters, was the blade was slowly splitting apart and finally caught itself on the shroud, violently ripping the rest off it one go. Sheared sounded like the right descriptor, perhaps Cleavered is more apt but not among the jargon you'll find in the technical specs. =D
@@AgentJayZ do you think the distortion on the shroud occurred when the blade failed?
