Fantastic work as always, Tom - it's so cool to see you squeeze more and more efficiency out of these engines. Over 3 years I've yet to see a video of your's that isn't interesting and engaging. Here's to many more!
Honestly my favorite part of all this is how realistic this engine sounds. It makes it sounds like a classic style prop plane and I really like that! Well done!
@ Tom Stanton The pressure siringe flow control MUST BE APPLIED to a water bottle rocket. So... Did you read that MUST? So it means you agree? OK enough for now.
Dude my jaw literally dropped. I was thinking off all these complex, and heavy ways he would have to use special circuits and sensors and then all he needed to accomplish it was a syringe. A FREAKING SYRINGE! brilliant.
I feel like that's "just" a pressure regulator, but the simplicity of the design and usage of random parts like the syringe is great. In general, I did not think it's possible to 3d print air engine due to things like inaccuracy and friction, yet here we are!
Someone gave me one of these when I was a kid. Even when the plane itself broke, I was so obsessed that I took the internal parts out, and was always trying to make different air crafts using the tank, motor, and a lot of paper.
Good to see you here Dustin. Maybe you should do a collaborative project together, knowing that you like to collaborate with other teachers, you should definitely get together for a video.
Use the exhaust ports as a form of propulsion, force the air in the opposite backwards and narrow the tube to increase the amount of force it produces. This may help the craft to fly faster and for longer
@@ergile172 nah, the actual exhaust ports would be the same size as they are currently, meaning the same volume of air would be expelled at the same rate, just a different direction
There is no way you could get any substantial thrust from a nozzle with that tiny bit of air the engine uses. Plus, using compressed air for thrust is just incredibly inefficient.
@@derrick4804 I know, but marginal gains is all you can hope for with an engine like this. It is never going to be efficient at all, just trying to suggest some potential changes that make it function better and look cooler 😎
@@1nvisible14 Yeah, replying to youtube comments for senseless videos is a much better use of time. Lead by example. Screw hover bikes, terrible waste of energy for no reason.
You're clearly getting enough out of the engine to sustain its flight far longer than a glide, so I'd say you've been quite successful so far. I'm astounded at how good a plastic drink bottle is as an air reservoir and I love your syringe-based air regulator... that's just bloody _inspired_
The drink bottle working under pressure actually makes a lot of sense. Initially you think "oh it's just a drink bottle" but it's been designed to hold gas pressurized into a liquid and hold that pressure when being shipped across the world. Considering it can do all that while costing likely less than a cent in materials is quite a feat of engineering.
Hello Tom! As mechanical engineer (in aeronautics and drones), I am fascinated by your design of a compressed air thruster (with printed parts). I would like to say you "Congratulations!". Did you try to move back the air tank + compressed air thruster? I have the feeling that the mass center (or center of gravity) is too much ahead. That is probably why the nose dives (maybe also because of the thrust). Concerning the thrust : did you try with a transmission ratio different to 1:1? The diameter of the pinion and the wheel seems equal (then the ratio =1:1). Try with a ratio 3:2 or 2:1. Your screw propeller will turn faster (you may loose torque. You may have to find a trade-off. Is "trade-off" the correct english word to be between 2 stresses or 2 situations?). How fast is your propeller? Did you gauge the torque? To finish, you maybe need to make higher wings. It will be a pleasure to follow this project. All the bests! :)
Hey there bro. I'm a student in the field of aviation and my career goal is to become an engineer in aeronautics. Do you have any tips or headers or anything you would share in order to get a successful opportunity during and after graduation. If so, please provide me with the necessary information, and it would be greatly appreciated.
Hello,@@alexandrerouleau9971 I would use the word "compromise" instead of trade-off. while trade-off is a similar word, it is used more in situations like: "you will loose some torque but in exchange for double the speed I think that's a good trade-off" (now you are referencing an actual "trade" here being torque traded for speed. Furthermore the word trade-off also implies a certain "benefit" for one side. Here speed being more crucial for a propeller than strength hence the speed is a larger benefit.) Compromise means exactly what you ask; to find a middle ground between two situations. Note that compromise can also be used instead of trade-off in the situation above. People will understand what you mean though, and there was no part in your messages that was unclear to me. I hope this was clear for you! disclaimer: English is not my first language either, but I did grow up _almost_ bilingually.
I will be willing to help in any software engineering related fields in this project as this project is a game changer if it can be scaled to real size air busses
@@MortonPNZ you are probably right, we have to find a compromize of the mass center position : - Too much moved back : it will pitch up, and loose energy to fly - Too much moved ahead : the nose dives to much - Correctly positionned : it will fly longer I absolutely agree with you concerning the thrust angle regarding te fuselage. I didn't think about it for a model which its construction is "simple". But when you think about your solution, he can actually improve its angle by using corner spacers. In every cases, he needs to compare its behavior depending on the different physical characteristics. I'm pretty sure that your solution and mine will improve its flight.
That's because it is the same basic idea as a combustion engine, minus the BANG in the cylinder. Anything like this is going to rely on the movement of air, whether there is combustion or not.
Didn't Airhogs have ones that would fly horizontal like in this video? Do they work on a similar principle with the engine? If so what allows them to fly so well?
Vertical flight requires a much higher power-to-weight ratio than horizontal flight. If it's this difficult to make this engine fly level, it would probably need some major improvements for vertical flight.
@@MF175mp it was a risk but it could've been avoided by waiting until warmer climate and even warming the o rings themselves. They launched it in a very cold climate it wasn't really a risk but more of a guarantee. This was an unnecessary and humiliating failure costing several lives and lots of money.
My dad was born in 1913 and fell in love with model airplanes and later aeronautical engineering. He got to see aviation grow from Jennys to SR71's. He was temporarily crippled as a kid & spent a lot of his time building models that included a hand built a thin copper foil air tank spiral wrapped with a very thin wire and dome ends. He built a 3 cylinder engine to go with it. I never saw any of his planes or the plane this power plant was in but it still had the propeller so I could pump it up and spin the prop. Unfortunately he threw all of his old models & related things away except for a silver first place cup he won in a contest where his rubber powered plane "flew out of sight". "Yesterday's junk is today's treasures". For sure!
...but it veers off to the doldrums 42 times before he cracks it...love Toms dedicaton and perseverance...far too many of us just give up when the going gets only slightly tough.
I'm not an (aeronautical/mechanical) engineer, and I'd never seen this design before - and I've already got a possible idea that might improve it. I suspect that idea has likely also been independently done by someone in the distant past.😂
"I think with a little more weight saving and some normal weather, this plane might actually be able to fly a full circuit".... how about some more space??
He used a field but because of the cold weather he had to pressurize inside and fly in the garden... with warmer weather he could use the field without the engine underperforming
The cat sneezed in the other room so I redesigned the engine to save 4% weight. Then I ate spaghetti for dinner so I redesigned the engine to make 3% more power.
Agreed, this might be a great application for that, providing he can keep the internal surface smooth/accurate enough to work, this is a bit of a high tolerance use case. Non PLA plastics might help too, PETG, Polycarbonate, or even a high durability resin print might be interesting tests too
as a mechanical engineer and teacher/researcher at university, I look for students with the most imagination, not the highest grades. you certainly impressed me, keep it up!
I was looking for someone answering you with this, you NEED to COVER the underwing to increase lift and reduce turbulence. The concept looks stunning! keep on it :)
I still have one of my son's old Air Hogs pneumatic powered planes. I'll have to take a look at it's engine design. If I remember, it was made of clear plastic, so should be easy to see. We had a lot of fun with that plane!
I got that exact model for my 5th birthday back in 1999 lmao. Damn that commercial has caused an avalanche of nostalgic childhood memories haha. Thanks for sharing!
Really smart ideas and quick, practical test modeling. An office light tube storage container may be a good candidate for another low pressure model with higher volume. Long skinny fuselage. Might require a girdle if you have strong seals though.
How great! A self-contained electromagnetic compressor and storage compartment to power a super light and efficient pneumatic system!! It's the future of aviation! Congratulations my friend!
@@Taunus-Tim well yes, and to be precise, there is no combustion happening here, and the combustion is part of what makes the sound of a classic combustion engine. the compression and decompression of the gas is cool and sounds dope, and that's a-okay and doesn't need a "well, actually..." attached to it ;)
@@itisjambo correct. And thats the same here. We have compressed air, and we decompress it in front of that 3D printed piston. Or to be exact: when the outlet opens. No expansion inside the engine happening here.
When you do the 3D animations do you need to time all of the moving parts or does it use some type of physics engine to compute the mechanical motion? I have been trying to figure how to make gears self animate based on physics in fusion but no dice.
Try using a motion link between the two gears. It should work as long as the gears are components and lined up correctly. If the gears are different sizes you might have to adjust the ratio in the motion link to match the gear ratio. Hope this helps!
Note that Aaron Luke's solution, which is a good way to animate a mechanism, does not require any rigid body simulation. It's simply synchronised animation, very light to calculate
Keep it up Tom! I love your strive for the difficult projekts rather than the seemingly impressive ones. Your analytic approach to the problems is a joy to watch. Testing and understanding the mechanics from scratch is the most interesting part of engineering. That’s what I think and it feels like we have that in common.
you could have put in some landing skies to protect the propeller while landing, it would stop the plane from braking all the time too, you can make the skies very light weight.
3 Suggestions: Cover the underside of your wings. Make an elliptical wing tip. (saves weight and is more efficient) Consider the gear ratio you're working with and the RPM of the propeller. Props have a best RPM, and I have a feeling you're undershooting that RPM significantly.
I completely agree! Sealing the wing ribs from the underside would achieve the tear shape to increase lift, since it seems like he has always to bring the tail down so he can keep the nose of the plane facing up. And the up-tilted tips are to keep the plane more balanced when turning and they don't have to be this long.
I believe that if you closed the main wing from the down side, it would create that tear shape (from the side view) and greatly increase lift on the front-middle part of your plane. At 3:35 if you put something like a thin carton on the down side of the wing ribs, to "seal" them from air outside, it would help a lot.
I always see your projects, they are so interesting and fun. I recommend you design in the front of your plane where the engine is located a part that can absorb shocks and prevent engine breakdowns.
This video is so beautiful. Have you considered using some other vessels - such as compressed CO2 capsule - which could afford higher load & pressure? I would really love to watch this project till the end! Thank you for the great work!
please revisit the compressed air plain, there is a design where the piston runs within the drive shaft and the drive shaft acts as the valve and valve timing with a small hole at the top of the combustion chamber (which is also the drive shaft)
This kind of projects is what makes people buy 3D printers, just amazing!

I like how this engine still sounds like a combustion engine.
No combustion engine makes u deaf
That plane just keeps looking for the hard place to stop!
Cause in some regards its similar to a combustion engine. Using a piston and a gas with valves. It's not a combustion engine but similar.
That's because it is the same basic idea as a combustion engine, minus the BANG in the cylinder. Anything like this is going to rely on the movement of air, whether there is combustion or not.

covering the underwing will improve lift by reducing drag
Yeah your right I thought the same thing
Also moving the wing closer to center of weight
I'm a cfd engineer, I bet that this is the worst design for a lift. The under wing has to be covered to reduce drag and to increase lift
This is very cool, but I'm certain the wing needs a bottom surface to be an effective low-speed airfoil. I hope this helps.

Hahaha yes, I thought that too, it looked past it for ten minutes ;-DD
No he marks the object with pheromone glands
I love the fact that it even sort of *sounds* like a conventional piston engine yet there is only air... love it!
To be precise every piston driven combustion engine is only working with compressed (but hot) air/gases.
@@Taunus-Tim well yes, and to be precise, there is no combustion happening here, and the combustion is part of what makes the sound of a classic combustion engine. the compression and decompression of the gas is cool and sounds dope, and that's a-okay and doesn't need a "well, actually..." attached to it ;)
@@itisjambo correct. And thats the same here. We have compressed air, and we decompress it in front of that 3D printed piston. Or to be exact: when the outlet opens. No expansion inside the engine happening here.
When you do the 3D animations do you need to time all of the moving parts or does it use some type of physics engine to compute the mechanical motion? I have been trying to figure how to make gears self animate based on physics in fusion but no dice.
Try using a motion link between the two gears. It should work as long as the gears are components and lined up correctly. If the gears are different sizes you might have to adjust the ratio in the motion link to match the gear ratio. Hope this helps!
Note that Aaron Luke's solution, which is a good way to animate a mechanism, does not require any rigid body simulation. It's simply synchronised animation, very light to calculate
@@Aaron-sh1vq I'll give it a go!
@@rpyrat True, the motion link is a just a simple simulation that will display how the gears interact
It looks like Blender (which allows each subassembly to be animated along a path or axis)
I don't know why this was "recommended" to me, but I couldn't stop watching once it started! Amazing design and effort! :D
Same, this guy is now the smartest stupid guy i know.
7:18 that **sigh** tho, i feel you man,,
Keep it up Tom! I love your strive for the difficult projekts rather than the seemingly impressive ones. Your analytic approach to the problems is a joy to watch. Testing and understanding the mechanics from scratch is the most interesting part of engineering. That’s what I think and it feels like we have that in common.
This has a prime example of how here in England even if it gets below 0 Celsius we will never get snow
Our weather sucks.
@@timehunter9467 I think its great, not too hot (mostly) and not too cold
We got snow in the south, about a week ago. My snowman's still kind of standing!
you could have put in some landing skies to protect the propeller while landing, it would stop the plane from braking all the time too, you can make the skies very light weight.
3 Suggestions:
Cover the underside of your wings.
Make an elliptical wing tip. (saves weight and is more efficient)
Consider the gear ratio you're working with and the RPM of the propeller. Props have a best RPM, and I have a feeling you're undershooting that RPM significantly.
Of course!!!
I completely agree! Sealing the wing ribs from the underside would achieve the tear shape to increase lift, since it seems like he has always to bring the tail down so he can keep the nose of the plane facing up. And the up-tilted tips are to keep the plane more balanced when turning and they don't have to be this long.
Вот и я о том же.
1. Где нижняя плоскость крыла? 2. Неправильная развесовка / центровка
3. Тяжелая конструкция для таких оборотов двигателя и винта.
completely agree even if it's paper or something it would greatly increase lift for sure.
@@ЮрийВоробьев-ц9н Нахуй ты на русском пишешь на канале где все говорят на английском?
The syringe regulator got me! Thats so freaking cool! I'm supporting you now. I really hope you get an air powered and radio controlled plane flying!
I really love the sound the engine makes, great job!
thats such a clever little motor ... all run off compressed air wow... good job bro xx
4:16 😂😂😂 that disappointment! After all that work and it just breaks first flight. Good job Tom! Never give up!
I admire your dedication. This is how inventors prevail.
4:13 : The plane is my hopes and dreams, and tom is me.
I believe that if you closed the main wing from the down side, it would create that tear shape (from the side view) and greatly increase lift on the front-middle part of your plane. At 3:35 if you put something like a thin carton on the down side of the wing ribs, to "seal" them from air outside, it would help a lot.
4:44 xD - The comedic pause made me LOL, good editing thanks.
10:33 just loved how the cat was looking at the old wallet and saying, you won't be missed anymore!
nice plane though!
It's like a DIY Air Hogs! Very cool, Tom.
Those were fun!
@@Themaxwithnoname They were, it's a shame those broke way too easily, i miss those
Remember those ads? AIRHOGS!!
How have I not found this channel already. I don’t know if I’m going to be able to sleep before I watch every video 🥲
Been watching since the first iteration, always interesting watching your development of this. And that’s a lovely Burmese kitty. 👍
It's been great watching the progress of this idea, and the engine sounds so good!
Awesome stuff. Try putting some dry ice is there. Constant high pressure source. Relatively common, at least in the US.
the starting weight might be an issue but i wonder
That's what I thought too, but the cold air would probably make the rubber diaphragm crack.
Or power it off a CO2 cartridge. The initial design was to emulate the Airhogs planes though so that's admitting failure.
I always see your projects, they are so interesting and fun. I recommend you design in the front of your plane where the engine is located a part that can absorb shocks and prevent engine breakdowns.
This video is so beautiful. Have you considered using some other vessels - such as compressed CO2 capsule - which could afford higher load & pressure? I would really love to watch this project till the end! Thank you for the great work!
Tom Stanton: Able to find a tiny piston in a spot with decently high grass and leaves
Me: Unable to find a nerf dart after shooting it in my room
I felt that.
Especially considering i also have a Rival blaster... Trying to find those yellow pricks if they roll under some furniture is a *pain.*
@@camillecirrus3977 oh bruv, the *pain*
It is because they fall through the "roach" limit, and either disinegrate, or run into a dark area. ;)
@@YodaWhat genius
Honestly the syringe based regulator blew my mind. Amazing engineering...
The way his cat look at the wallet when he threw it at 10:32 lol.
Merry Christmas Tom, thanks for the content x
Wow, you did a very good job engineering that engine. That was incredibly interesting to watch
Wow man, you've came some way, I love the new design! I'm glad that this version almost does a full circuit
please revisit the compressed air plain, there is a design where the piston runs within the drive shaft and the drive shaft acts as the valve and valve timing with a small hole at the top of the combustion chamber (which is also the drive shaft)
Awesome👌
