Of course its a German making backyard jet engines.
its just a nozzle not the engine
@@2muchofyou he made the engine
eric mazialnik yeah, they’re not very good at the real thing
@@jb76489 Exactly it's not like they made the first flying jet plane or anything. Oh wait...
=D Well one got to blow the leafs one way or another.
New Title: "Testing more fun ways of moving a table". Amazing project btw.
what a genius
How are you not verified yet?
Turnah? Wasn’t expecting to see you here
Oh, Turnah...I did not expect to see you here....were you, by any chance looking for ideas to upgrade your pogo crutches?
Excellent , excellent
Thats amazing, it would make for an excellent vegetable strainer
:O hiii
Hahaha
Or perhaps, a vegetable strainer would do a great turbine nozzle!
No no, a folding dainty cake caddy thing....
3 miles down the road...”Honey, is there something wrong with the vacuum cleaner?!”
Well now you just have to make an afterburner👌
Hi,
think about afterburner!
Before more tests👍
Andy
Reheat does that- hit us up @Praendy
A variable nozzle is not very useful on a non-AB engine. I have to wonder if this is just a step toward that goal. I cannot however just summarily discount the cool factor because...yeah...its cool! Awesome job!👍😎
Great for scale until afterburners are achieved, now move into a vectored thrust and you’re golden , very , very cool man
@@dirtylatte Hi,
engine is not made for airplane. Its a show model for display, or meetings!
I like to play with those mechanical components and yes, there is also a little positiv effect😉
You feel the acceleration of exhaust gases and you hear it.
Thank you👍
Check Part 8!
Cheers Andy
5:00 When you make a precious jet engine by yourself, you check the engine temperature by touching it !
Dude must have either been really confident or really stupid to put his hands that close to an object spinning so fast.
@@LimitedWard Hi,
unfortunately there is no other way, to check vibrations.
All is balanced by hands and at some rpms, there are small vibrations noticeable. Thats why I check the rpm according to rpm.

That's how real men do it
When you know the engine so well that you know where to touch and when ;)
That nozzle is a work of art mate. Nice work.
Teacher: we are learning about who made the jet engines and how does it work
The silent kid with 2 jet egines at home: i guesss i doit my self
Where is that school where they teach KIDS about jet engines? If you'll find one I'll make a kid just to sent him there.
@@ardvark84 aerospace class? I took it in highschool
@@Dappersworth So you were a teenager not a kid.
@@ardvark84 nobody says "the silent teenager", the silent kid refers to anyone in school regardless of grade that is the silent type, i shouldnt have to explain this
@@Dappersworth oh OK, of course
I just saw a table flying by overhead
1:42 I got a rough understanding of how a jet nozzle works in your model for the first time. Thank you!
The CCCP would love to know OUR location :D
I suspect the big ones on planes work on hydraulics instead of wires.
@Rafal Molak well apparently a rough understanding of respect can't be obtained from whatever book ur reading
1) the variable nozzle system is gorgeous
2) pairing a jet engine with Pnuema is legendary!
Awesome! I couldn't believe it was made in a garage. Looks like it's ready for thrust vectoring.
Came here for the Nozzle, stayed for TOOL!
Tool!!!!!
The tune was so familiar
Tool for life!
even liked the video because of tool
I haven't listened to the new album yet.
I recognized it was Tool immediately. They have a unique instrumental sound.
I had a friend who died in 2017 at age 38. He really loved Tool. I feel guilty listening to the new album because he didn't get to hear it. I'll take a listen later today maybe.
Any man brave enough to stand next to something spinning 10-25 k rpm has my respect. Cool project!
Dude thats very very low rpm for the Gas turbine engine.
More like 125K rpm.
GT, these small units are just like small animals versus elephants. Heart for a mouse is 100 plus bpm, elephants about 30. A large turbo fan has so much more energy involved s. These small units, such as a Jetcat reach and exceed 120K.
Hi,
just for information! This engine is made to reach max 70 000 Rpm, because the turbine disk is limited to this speed.
Smaller engines with about 70 mm turbine running 115 000 Rpm or more.
My turbine wheel has 130 mm diameter. There is much force on every turbine blade.
Next goal for me?
Reach the 70 000😉
Andy
@@Praendy wow, that's way-fast. I hope that spaghetti pot can contain any negative event!
Makes me proud when I see the things my people can do with little effort. Well done sir.
Forgive me but NOTHING well done comes with “little effort”. All things well done are done BECAUSE of a lot of effort.
really cool! what effect will the nozzle have on trust?
Don't quote me on this but I believe it increases air speed but reduce thrust power. Kind of like your water hose when you put your thumb on the end. Same amount of water but higher speed, but increase fuel consumption because of pressure build up.
If I recall correctly when the throttle is low, the amount of air leaving the nozzle is not a lot so a narrow nozzle is best for performance. When the throttle is high on the other hand a lot more air leaves the nozzle thus to get the peak performance out of the engine the nozzle would need to be wider so the air can exit the engine freely without circulating inside. Low throttle = not much air, narrow nozzle; high throttle = a lot of air, wide nozzle. Sorry for my bed england and thanks for coming to my ted talk.
Just look up "nozzle thermodynamics," that should give the answer, basically it increases velcoity of a fluid(air) at the expense of pressure, and can accelerate subsonic fluid to contribute to thrust.
People will trust him as an engineer?
I don't believe much. Pretty sure the nozzles are for afterburning engines. I would be surprised if this had that.
and we're listening to Tool. I'll stick around for a while ;)
Was thinking the same thing
TH-cam recommendations strikes again with the random yet satisfying videos
Will be crazy to adapt that for thrust vectoring. Good luck!!
Later that day, a table crash landed in Trondheim, Norway.
Seriously, however, beautiful workmanship. You have my genuine admiration.
Looks brilliant! It’d be great to see a comparison of the thrust with and without the nozzle using a sled or something that can attach measuring equipment for the output.
Hi,
this will be the next step!
Teststand already built.
Andy
@@Praendy see if you can come up with a design that is telescoping like the iris doors you see in sci fi shows ... or like on a camera lens ... then you can also work in thrust vectoring with exhaust constriction for better fuel to thrust conversion ...
Trust vectoring... And an afterburner valve 😂
@@dg9bfc typos are fun trust vectoring ... yup cuz if it fails you lose all trust in it ... yeah I know tHrust vectoring

And who built an Atomic Bomb in their backyard today?
Well the nazis did actually invent the jet engine, also a pulse jet engine, meant for the V-1 rocket.
@@longwong1016 it wasn't the IZAN ...but Henri Coanda did. check out his 1910 Paris aeronautics Expo model . so...Henri Coanda was testing basically F16 Jets in 1910 when everyone else was building flying bicycles . He was Romanian, so yes Romania and Germany were allies and he went to work for the izan.
Awesome, your understanding, knoledge and skill to make it is high level.

Had me at the soundtrack
Boy oh boy has technology come a long way
I wasn't waiting for that music. Nice TOOL!
Amazing! looking forward to future developments .
My first reaction is that usually military jets do not have variable nozzles unless the aircraft is supersonic. The idea is to produce a gas flow which matches the speed of the aircraft so that there is effectively zero kinetic energy going into the gas and it all goes into the aircraft. IE if the aircraft is flying at Mach 1.3 the gas needs to leave the nozzle at mach 1.3 so it is realtive to the atmosphere, stationary. The second point is that for a nozzle to be effective there needs to be a gap between the turbine blades and the start of the nozzle. The gap is a function of the diameter of the engine but I don't know the equation for it. My guess would be that at least 10cm would be needed for an engine that size possibly as much as 20cm.
Gordon Lawrence the nozzle is also there for protection of the engine if you have an afterburner, the pressure in the nozzle would be to high for the engine to work safly so the nozzle opens up when the afterburner is ignited
I also thought it provides thrust vectoring?
@@motokid6008 Not that type of nozzle. Some can though but they need individually controlled petals instead of anular ring controls. IE petals controlled by a single ring rotating. Anular ring control is most common as it is by far the most simple system.
Are civilians not banned from using variable nozzles? I thought the millitary did not allow it.
@@redmonkey3556 Definitely not in the UK as there are significant amounts of flying "retired" RAF aircraft in private hands. There are even BAe Lightnings in private hands in SA and one of those is so heavily modified it had the record from standing start to 100,000 feet for a while.
This is a truly engineering marvel, all the best from Portugal! Awesome job!
always the ultimate respect for getting a jet engine right in the backyard!
Came for the jet engine and enjoyed even more when Tool started playing!
This is a rare mod haven't seen one of these
That’s because it is functionally pointless on an RC jet engine.
That looks SO cool!!!
9:19: Houston we have a problem.
What is so very cool about your engine is that you run it and run it and run it. Most DIY jet turbines are run for a few seconds and then shut down (or they break).
I have an older model Jaguar and occasionally on nice days when traffic is light in the interstate near my house I run the car at it’s redline. The first time I got up to 132 mph and was so freaked out at how fast the relatively light traffic ahead of me “caught u to me” I slowed down immediately. But now I will let it ride for a several minutes at which my fear of any unseen state patrol takes over and I slow down. But between that first run-up and then immediate slow down and getting up to speed and holding it for a while, the difference is night and day.
Your work (and play) is such a joy to watch.
Imagine being his neighbor trying to relax in the backyard
Tony Stark: OK Jarvis, let's start at 10% thrust.
This is one of the greatest things I have ever witnesses. It'd be awesome to see this in a scale model flying around. Could you imagine >:0
This is much better than the earlier turbines I have seen guys make with melted aluminum. Well done.
Sounds like some great sunday afternoon fun!
Germany can't produce any military weapons.
But they didn't mention the civilians
But have people to be able to make it.
we produce a lot of weapons for export. Like last year we exported weapons worth roughly 8 billion Euros
Just Tom makes you wonder how much is secretly kept. I would think Germany could have weapons by now. Not the same culture as the past but I wouldn’t know in reality.
@@liggerstuxin1 what do you mean we have a military you know? We are literally one of the biggest weapons manufacturer in the world and are part of the NATO and we participate in wars. We just aren't allowed to start a war on our own.
Just Tom That’s so interesting. Thank you for informing me. I don’t know a lot about the legal powers of Japan and Germany.
I mean some people complain when their neighbour is mowing their lawn in the evening. And his neighbour has to deal with a litteral jet engine starting! Love it! Haha

You mean the Kaveri engine?
This is just an model engine and this thrust is very very low compared to our country Kaveri engine.
@Al Wa 王八 王八蛋 Winnie D pooh dude, I was just confirming that he was thinking about the Kaveri engine. There is obviously no comparison between the two.
beautiful piece!

@I'm Just Kyle idk I thought it was
it is an adjustable thrust nozzle like in fighter jets - but it is only effective in combination with an afterburner.
After the first few notes I looked up from my phone and gave this a like
amazing part, congratulations!
Beautiful engineering!
I've subscribed now looking forward to seeing more very beautifully engineering keep up the good work
Nice work. I have built thousands of large jet engines but really would like to build one of these as a hobbie. I enjoy your craft and skill.
Yea right
real size full size jet turbines and hobby sized ones ... talk about LOADS of difference ... there are a load of compromises between hobby size and full size ..but finding them and deciding on how to make as little a compromise as possible is half the fun ;)
I love all of these videos with these brilliant lunatics.
fantastic work!
In my head all Germans do this as a hobby.
Would be interesting to see the fuel efficiency on this jet engine.
Fuel "efficiency" is not a word that you commonly hear haha.. see the size of the fuel jug he is using on the test bench.. tells the tale right there about how much fuel it burns. Also watch the bubbles at the 4:43 mark go through the fuel lines when he is getting it primed and running....
jet engines.... aren't well known for being efficient.
There's a reason why the jet industry is on par with the car industry for carbon emissions, despite the ludicrously smaller amount of jets flying around than cars even taking into account the larger size and carrying capacity of most commercial jets.
Since it isn't doing any work or moving it's fuel efficiency is probably 0
SRS the work it’s doing is moving air through at high speeds, there is literally fire coming out the back and not just straight up
@@epichappyhappy2506 so a really inefficient and poisonous heater then...
Great craftsmanship !!
