Homemade Jet Engine
Checkout www.wppe.co.uk . This is my latest homemade jet engine. It has taken three years to design, make and test. A new lighter, smaller and more powerful engine is on the way!

Really cool project my friend -- NI's LabVIEW is so great right
Please dont angry... Try to flow the hot air from exhause , into outlet chamber (will added preser turbine) , and... Make another branch exhause , IN the first exhause... ( It's Not AFTER BURNER , ... buy the way...) That's will make more eficient of avture... Please try.... That will be a new generation of jet engine...
Thank's for Replay... Best regards, Nurmogati.
Btw... I made a new rotary engine... Now , I turn air drill , but on future , may , that system will use... and all the world knew , there is a new kind of rotary engine... From Indonesia... I want to know... At first , did RR buy ... Or make agreement with Mr. Nicholas Otto , because use Piston Engine for driven...??? And if... If improve that New Rotary Engine , have make agreement buy using Air Drill , which have patented...??? Please wacthing " Home made Engine" There is mine... Overthere...
Do real jet engine when air craft was flying , the exhause was burn like that...???
Forgive me for the preposterous idea, but you should make a jet engineered espresso maker
Hehehe, I wonder what gave you that idea!
How many thrust lbs?
Awesome !! 10 years goes by, but i never bored to watch this video.
Please more informations about how made exhaust turbine. My project like yours and i stuck on that part until 1 year.
Math , check..machining,check...welding... weldingtipsandtricks, good UA-cam...just saying.
😂 it’s not got much better since then 😅
@@9baristaespresso all in good time, as long as we are trying. It'll come.
How many cost build this Jet Engine??
Great music I'm a jazz drummer! Great job on the engine! If you look at my Gmail image , it's a picture of the Terminator. It took me a year to make ( all metal ) non killer cyborg. Now I've seen your UA-cam post . That's the next thing I'd like to make . Is it ok to copy your work? Thank you!
How can i contact u
Quite similar to the 1930's - 40's Whittle jet engine. That design was simple and reliable.
Very cool 👏👏👏👏
Newer Jet engines run on compressed air and very little fuel.
Wow, this design is so neat that I think you might be an engineer!
Good work William!! 3 years development.. from idea.. gathering info.. plan.. purchase lathe and other equipments..hahaha
I need two of them to keep up with my proyect
Sublime
give formulas pls
yeaaaa...... !!! that worked !!
Nice work, but that musik is horrible...
Designed by a real engineer with his own state-of-the-art research machine shop...
Ok, I know I'm late to the party here, but I have seen video after video of people trying to make engines out of soup cans and bicycle parts. I'm very happy to finally see someone who took the time to do the math first, and use proper materials. Good job. Several years ago I build one by Kurt schreckling (sorry, I know I misspelled that), and have thought about trying my own design, but I just can't get over how many people are really screwing this up. Someone is going to get seriously hurt by these soup can engines. Anyway, great job to you, and thanks for a great video.
This really is fantastic! Monday morning made!!
I tilt my hat to your sir
this is the funniest looking jet engine iv ever seen in my life lol id call it the fat man !! lol only one thing man .. why the hell did you weld it together !!!!???? that's a big no no !! now it something gos wrong and something will go wrong cause that's what jet engines do you can not take it apart to maintain it !! 2 years and you couldn't think of a way not to weld it ?? lol
All the required parts that assemble the brunt of the engine are bolted together. Only these parts have welds in them and that is for stuff like flanges and guide veins
Yep, as @Draylogic said, then engine can be fully disassembled through flange interfaces
How about the sensors for indicators?
I got most of the sensors from here: www.phidgets.com/
Where did you learn the mathematics necessary for this?
The maths is pretty straight forward - it's the understanding of thermodynamics which is a little harder to get your head round. There's a book called Model Jet Engines, by Thomas Kamps which guides you through the practical process of designing an engine. It's excellent. There's another one called Gas Turbine Theory, by Saravanamuttoo which goes into more depth on the theory side of things - also very good.
William Playford Jeez, I didn't expect a response that quickly! Thank you. Out of interest, how's progress on the second engine coming along?
+Patrick Bateman The second engine has been on hold for a few years now - it's half built. Hopefully I'll find the time to pick it up again soon. I'm working on a new espresso machine design now, which uses some similar thermodynamics to the engine. I should have a video of that up soon.
William Playford Good to know. Does the book deal with things like how to make the engine self-sustain?
+Patrick Bateman Yes it does. Whether the engine self sustains or not, is down to how well you have designed and made the thing. If the engine generates more energy than it is consumes, then it will self sustain.
Please come visit my page. I run a 70kg thrust engine on a bike.
Fantastic work!! Thanks for sharing, this video inspired me to build my own!
Congratulations, The best engineering in your project!!!
#EXCELLENT, I've no more to say.
also check out my "learning experience" jet engine. Its a laugher. ua-cam.com/video/QW8cPzx6bxk/v-deo.html Were you ever at the level of jet engine understanding we were in this video?
Great stuff! Yes, I definitely was. I built something very similar a long time ago. It didn't run. A good starting point is to build an engine from a turbo-charger - you'll just need access to a welder and an angle grinder.
Please put it on a bike
+quinnscoolscience Done that....

Wow...Rolls Royce
Iv always wanted to do this but no one is nice enough to tell me how to do thr math
Did you try with a curved inlet? it should give the engine a much better inlet airflow. If you take an electric ducted fan and test it with and without a curved inlet, you can easily hear the extra noise created byt he disrupted airflow if you don't use the curved inlet and the air goes past the sharp edges, creating a turbulent air flow. This should be especially important for static tests.
did you really make it by yourself? can you guild me to design simple one similar to this engine?
Awesome job! Well done!
What is the diameter of the compressor wheel? What are the RPMs while running on it's own?
Its self sustaining ok....the only problem you seem to have is a very high temperature in the NGV section. This is down to combustor design. For such a large engine, it looks a little on the short side, which means you could afford to make the Combustor longer. Are you using reverse flow vapourising tubes in your Combustor?, if not, then I suggest you try them. I made my own engine also, some years ago..I have a flight clip up if your interested....Dont you find the comments amusing from those who dont know what the hell they are talking about? Some of them are priceless...:)
Say William... what was the final thrust in LB's did you get from this engine. Also was it throttleable at all? Most jet engines of this size tend to runway or won't let you dial down the thrust without flaming out.
It would be awsome if you upload some videos explaining how to design a jet engine
hahahaha yeah sure just do that
There are or were several books on the subject.. www.amazon.com/Model-Jet-Engines-Modellers-World/dp/0951058991 But over all it's really not worth the time. Small jet engines are hard to build and requires solid engineering. This is the first video where I've seen someone take the time to preform resonance analysis on the shaft, which is a major point of failure for small jet engines.. Once again great work... but I have better things to do with 3 years.
Put a fan blade in front of the compressor blade and make another airflow for the fan. That can make a lot of thrust.
that would be a turbo fan and it most likely wont work because it need to make that extra power to turn the turbine and the turbo fan .. it most likely doesn't have to power to work both .. you have to specifically design a jet engine to work a turbo fan .. he would have to put in more compressor stages instead on just one .. but its not likely to work a such a small engine that why you don't see turbo fans on jet engines of this size
End result : a lot of useless hot air...
Nice engine, By adding two more turbine stages do you believe it could reduce the amount of glowing heat? How many cycles your engine can hold ?
You guys obviously have too much time on your hands.
heard of hobbies?
corbonzo1 Heard of...Why bother..Its been done before and stop wasting your valuable life... ?
sandsifter149 you cant be serious... your life must be REALLY boring if you think hobbies are pointless. Why do you live? its been done before. Stop wasting air.
