That's why I like you Tom! You don't shy away from impossible projects!
yes
Hi integza
i watch all youre videos integza! keep up with the good work and succes on youre next turbo jet engine !
Collab when???
Yes
niceeeeee, thanks for the shoutout tom, you'll def get it in the next video
Before the shoutout, I was thinking; this seems like a thing @PeterSripol would do
woah, didn't expect you here
How do you pronounce a word where the repeated vowel is the silent one???

12:12 - The propellor on its own seemed to be doing fine :-) Great work, Tom. Enjoying the journey to air-pressured flight.
It's still spinning to this day, and although Tom doesn't know where it's gone, it still maintains correspondence.
Everyone is discussing the helicopter and I'm still here amazed that you just up and built a functional Schlieren imaging setup to look at your nozzle flows. Way cool!
I agree. That Schlieren imaging setup was awesome!
Yeah that was cool!
Yeah that was worth it's own video the shock cones were gorgeous
“hopefully we can put together some of these parts to make some thing that sort of does some thing“ that’s just all of engineering
I absolutely love how you aren't afraid to show your failures as well as your success. You tried a path and showed us the results and that's amazingly valuable!
Honestly I love seeing projects like this. I think so often creators want to have something that is totally functional and works perfectly to show instead of showing the design process. It is really helpful to follow your thinking and the process you go through to solve problems. Thanks for sharing this!
I’ve been waiting patiently for this video. I was not disappointed! I’m excited for the next video in this series.
getting smarter every day, i see
Hey! Nice to see you here!
dont sleep on your videos, the chicken egg video was lit
shut up daston
Me too!!!
“Not only does everything look better in slow-mo, but it also makes the flight time seem longer” - love it!
The music is a nice touch.
We can also analyze what's going on better to offer up our solutions!
The way the rotor continued with spin without the rest of the helicopter was really really cool.
Failure and destruction. Two events that benefit from slow-mo!
I love how you always use data to back up your decisions. Even many professional engineers skip this too often. When I saw you even built the schlieren imager I was hella impressed!
Next project: thermonuclear fusión engine that works by uranium CO²
😅😊
To counter the torque, without needing an additional rotor, you could attempt what the likes of the MD-902 helicopter uses; It still has the rear boom, but along one side it has a rib to reduce the airflow down that side, whilst allowing free-flow along the other side. This creates a difference in pressure, producing a moment; it might be worth a shot, but difficult to see if it'll produce enough of a difference
@12:17 Its really amazing how the gyroscopic effect of the sway bar kept the propeller stable and producing lift even when it was completely detached from the helicopter.
It reminded me of the bottle as a booster rocket lifting that rotor as a separate module.

@@redsquirrelftw Powered by compressed bread.
@@redsquirrelftw Oooh yes, with a LiPo power source. Genius sir!
I love this sort of stuff, splendid work! My immediate idea was the same, to reuse the exhaust from the turbo to counteract rotary action. Humble suggestions; 1. Place the bottle upright to maximise effective rotary thrust. 2. Shorten the turbo exhaust to a minimum and give it a tail. (The tail could be inverted). 3. Chill the bottle whilst pressurising to maximise available air mass over time. (Short launch time required, as the bottle warms from ambient air). 4. Upright launch mechanism would be simpler, in a number of good ways.
The way you showed the individual data points of the thrust to energy chart prior to fading to the trendline was brilliant! I will definitely start using that in my research!
It's gonna be a great day. Colinfurze & Tom Stanton uploaded video in the same day.
Right?! My thoughts exactly.
the holy trinity will be when wintergatan joins the two on same day
Watched both of them, great projects!
Best of British 🇬🇧🇬🇧😂
And the hacksmith!!
That Schlieren set up looks awesome and... Holyyy cow, that’s me! Thanks for the shout out!
Saw you at 6:08!
Big fan :D
you’re famous!!
Ay nice! Love your videos!
But i don't understand the use of the knife ?
Awesome experiment. Amazing stability of the rotor at the final section. I'm anxious to see this project succeed!
These videos are fun. Thanks for sharing your wins and setbacks with us.
Helicopters aren't easy, that's for sure. I'm currently working on a helicopter project...with counter rotating rotors about 1.3m in diameter and a square fuselage... and I'm giving it a 30% chance of success at this point. Was considering scrapping it but I love how you've presented your progress regardless of results. Thanks for the motivation!
For me helicopters and bikes are physycial bugs in the matrix lol
There's something not disimilar to that description that just flew on Mars !
Yeah, an air-powered 'bicopter' (like the RC Chinook) seems a lot easier to engineer than a dynamically-adjusting tail rotor.
@@nolanwaldner Jet tip helicopter could be a better solution than a tandem set-up like a Chinook. No anti-torque needed. Tandem would need equal lift at both rotors to hover. Counter-rotating might work because there's an increase in efficiency on the lower rotor. Still, jet tip rotors are were I would place my money when it comes to a compressed air system.
You definitely shall already know it by now, but anyway I just would like to remind about possible difficulties with swashplate mechanism. So is your team planning to buy one, order it on some factory or produce yourselves?
Just was waiting to hear about swashplate in the video, but now I assume aircraft controls are not discussed in these videos yet.
Few years more and Tom will build an air powered spaceship 🚀
Great job Tom, thank you for your channel
Well considering that he made impossible possible, he might do it
If it went to space it couldn’t couldn’t get air😳
I think a flat earther tried that recently. Last I checked he impacted the ground doing between 200 and 500 mph.
We already have that
Coke and mentos upside down
Like Mark Watney?
A successful engineer shows young people how one learns from and deals with failures in a productive and positive manner. I call this a pretty successful project! Keep up the excellent work!
You need a convergent-divergent nozzle to have a fully hyper-sonic flow, otherwise it will be blockage at mach 1
In Tom’s ideal society we wouldn’t use fossil fuels. The world would run on compressed air, truly the most glorious power source
Modern Steampunk
lol... and u will pump the air tanks manualy?
@@heaawk And how do you compress that air?
@@Rhynome more comprest air
compressed air fixes everything
4:29 The tyrrany of the air bottle equation! :-P
Massive Tom!
Great effort and really interesting to see your design and test process.
The project is Awesome, most especially because of the Air pressure motor
I think the stability can be achieved by adding some equally distributed weight to the bottle
I like also seeing projects that don't work as planned, because that's just how reality is sometimes. Only seeing the social-media survivorship bias can make one feel incompetent if any project fails, but seeing other people fail too is a nice balance.
What about dry Ice? - If you can get, 44g gives 22,4 litres of volume, N2 likes to expand as well. - Great Stuff, looking forward for next episodes!
Biggest problem with those will be embrittlement. Not saying it's not solvable, just that it is going to be a factor.
If you're here watching Tom and feeling inspired then keep going grinding away! We are all in the same boat here looking for ways to help all our channels. keep up the good work and Never Give Up!
Formula 1 cars with tractor wheels is definitely a race I would watch.
Bono, my tires are plowing
Kimi your tires are wearing quickly
Shut up I know what I'm doing
You should try using those little CO2 canisters as a source of air, they have about 800 psi so if it’s regulated it could last a while as well as being light and small
I think they would be quite heavy. And the problem is, you can't refill them.
@@generalfishcake There's CO2 canisters for paintball that are refillable. Some are even made of carbon fiber to reduce weight. The issue is that they're pricey and bulky. They'd require a larger helicopter.
Another issue is that the pressure they can contain is very high, not unlikely to grenade the turbine on the first run. And if you run it at a lower pressure, why use it at all?
@@professortrog7742 I was figuring that when the pressure is regulated it would be able to sustain itself longer, rather than releasing all of the pressure at once or in a very short burst
@@professortrog7742 There's this thing called a pressure regulator
I'd watch that slow-mo flight with relaxing music for hours.
I had a VertyBird when I was a child and had so much fun with that toy ....Thanks for the entertainment and memories.
that blade flying on it's own was magnifiscent. high speed 3d arena beyblades?
I died laughing when it popped off
Aerial beyblades! I'd buy that
"The clever folks over on Twitter"
Words I never thought I'd hear in my life
I will be trying this Schlieren setup today.
I used to have a little helicopter that worked on air pressure. The thing is it had a small plastic capsule that was filled up to pretty high pressure using a hand pump. I feel like all you need is a bottle that can hold more pressure.
This is one of those rare videos where I press the like button before watching the entire video. It's such a great thing to hear someone say something was hard and it didn't work. We're being shown so many success stories on the internet without seeing the failures, that it makes you feel worthless when you try something yourself. Showing a failure and then explaining why it failed teaches the same if not more than a success story. Thanks for sharing this and confirming why I subscribed to your channel.
Although I don't personally know him, this person sounds so friendly in every video!
Much love!♥️🇳🇵
Oh my god the slow mo had me there watching as if we were landing on moon again. Well done!
I really respect you for telling not only the success stories, but stories of failure (and learning) as well.
I love how it's not about the end result, but about the journey.
1:19 hugely underrated shot
The slowmo it’s beautiful!
I love the blades in slowmo flying toward the camera
All of Tom's ideas:
"Yo dawg, I heard you like air..."
LMAO, I'm just dying over here. My man Tom just made a bluetooth propeller at 12:15 hahaha
The stability of the rotor+stabilizer weights alone really surprised me. It just hovered peacefully for a (milli)moment there.
Thrust efficiency from a propeller also depends on the pitch, not just the diameter.
Pitch is usually given in inches, for model plane propellers - it's the distance the prop theoretically travels in one rotation, in a very idealised situation.
As a rule of thumb, a propeller with a ptich of half its diameter (e.g. 8x4 or 6x3) gives the best static thrust. For a prop with more pitch (e.g. 8x6 or 6x5), you get a better top speed, but less static thrust.
It's a lot like choosing a gear on a bike, or in a car, then driving in just that one gear.
Yay!! You're back. We all missed you.
I would like you power some of your previous projects using liquid nitrogen as a fuel source. Pour it into a mini tank. The air flowing over the tank can boil the liquid or paint it super dark black using special paints.
This is a cool idea. A cheaper and easier alternative could be liquid propane
You need to move the filling nozzle to directly underneath the center of thrust/mass.
Right now, what's happening is, the moment you charge the system enough for thrust-to-weight ratio to exceed 1, you start pitching forward because point where you're holding it down is well forward of the center of thrust. The moment you release the air supply is the moment where you are generating the most thrust you will ever be generating, and because you have to release it when it starts pitching forward, your maximum TWR is only slightly over 1. The moment you release it, the air supply starts running back down and you go below 1 TWR pretty much instantly, which is why your flight ends up so short.
Moving the filling nozzle to the center of thrust/mass, or alternatively, using a hold-down method that restrains it from pitching, means you can charge it up as much as you like and release with a TWR much higher than 1.
always clear always fun and always so beautifully lacking in ´let´s make telly´ muzak.. nice work!
The Air Hogs Sky Commander was an air powered toy helicopter that claimed to get 50ft high, it just had a large fin on the tail to help keep it from rotating, maybe something like that would work for you, and maybe some of their other design features could help too. I love your work and it has been so much fun seeing you try and make things move and fly with air!
12:15 when your car in BeamNG multiplayer near-misses something and the server desyncs at the same time so the other players see your car split in two but you're driving just fine on your screen
Oddly specific but ok
I can say that this was never a failure. It's just a stepping stone to something great. Hats off to your attempt mate...
The bottle in vertical and sharp edge to detach airstream from bottle surface?
Make a wind tunel to test the bottle minimum drag and what could make it slippery and expose less surface.
Golf ball dents etc.
I get to nerd out twice on theirs vid!!
1. I worked on the Mars Heli solar panel, and I have touched the panel that is currently powering it ON MARS!!
2. Now I work at a national lab and we use schlieren imaging all the time!
You wonderful lucky bastard! 😄
Thanks tom, this ones a banger
Takes guts to put up a "failed" project. This is what real science and engineering is all about. Not everything is an instant success. Thanks for keeping it real, Tom!
Excellent work. Probably anyone already tells you but perhaps tip jet propulsion works.
Good video Integza!
Thank you!
Tom: "As you can see it doesn't resemble anything in the title of the video"
Air: >:-(
Main rotor: "YEAH FREEDOM"
12:25, I love how the propeller keeps spinning as if the bottle is still attached lol
Legend is back again
Perhaps a pressurized rubber balloon inside of the plastic bottle could be used as an air bladdler to give your nozzles a little longer high pressure output time. Rather than the fixed volume of the bottle just resulting in a steady pressure drop. Cool videos btw.
Ideas for improvement:
- use some pliers-like printed arms to lock the whole heli around the bottle. You could avoid uneven upwards momentum.
- insert a tiny valve to stop the rotors running (and vibrating) while pressurizing the air tank. Open the valve remotely with a line.
- change the filling valve so that the levers presses the valve away from the heli.
->
1. Start up rotor
2. Stop pressurizing and drop the filling valve
3. Unlock heli
I really dig these videos man. Keep em up
1:40 look how stable the camera is in mid flight.
3 axle gimbal
The blades staying where they are when they snapped off had a looney tunes vibe to me.
I think you need a separate release mechanism so that the bottle can get to a very high pressure before disconnecting. notice your last try was working before pressure and thus rotor speed and lift dropped again. maybe a mechanism that releases automatically once the bottle reaches full pressure.
One thing to note is that you can create a helicopter setup like the CH-47. This was not the first heli with this setup, but it is one of the more successful ones. Why go to this setup. The first reason is that as opposed to having stacked coaxial rotors the dual rotors in this setup will allow you to increase your effective rotor disk area as well as canceling torque. Weight will go up, but you can also carry a larger volume of air. If the bottle size were increased to a 3L bottle, the volume will increase faster than the weight increase. I also have taken these bottles over 120psi over a few cycles and they have worked, so you may be able to increase the stored energy as well, though may need to change the fill method to accommodate the higher pressure.
Just some thoughts. It was a really fantastic video to watch, and awesome to see the shock diamonds.
If you don't fail sometimes, you're not trying trying hard enough!
12:20 that's awesome
That slow moe was epic. Like the opening to black hawk down.
Waited 2 months for this... and even though it didn’t work... your vids always teach me something well done Tom!
Who else honestly wants to see tractor tires on a formula One car because that would be freaking awesome 😂🤣😂
I mean why not lol
I'd rather drag cars! Hang on, that's tractor pulling!
Yup .. that’s what Ferraris are designed for 👍
I feel like we're about 2 years away from a "1:1 scale fully operational sherman tank powered by compressed air" video
I love the sound of that thing spooling up
Thanks Tom, I always learn from your videos.
I am simple man, I see Tom Stanton Video, I click on it
I just checked your channel 20 minutes ago wondering “I haven’t seen a video from here in awhile”.
higher pressure with a regulator i believe would be the only way. but your awesome this is awesome good work man. keep it up!
Idea: build a kite with control surfaces moved by servos. No propellers, fly just on the wind. You attached it with a single string to the ground, and it should fly by itself (moving these control surfaces).
After you can attached small propeller to generate electricity, and either send this power through cable to ground, or to use this power for servos.
Btw, great video!!!
He finally took my suggestion, yessssssss!!!!!!! Thank you so much tom!!
Never be ashamed of your failures!! Engineering is hard, it's easy to find what you did wrong, but it's really hard to find what you're missing. Keep looking at the math!
If you were to hold down the entire helicopter under pressurization instead of just the front you could get it up to higher pressure before takeoff and then just integrate the release mechanism with the one located at the tip
Great job Tom, you have inspired many peoples from this project.
Tom, I think I know how you could make a helicopter powered by a bottle of air. I won't tell you how and if it works I'll tell you 😉😉
In my head it all sounds great until I put it into practice. 🤣
Turn the bottle vertical to reduce downwards drag, a cylinder is a surprisingly draggy shape. I reccon you could see much improved performance without loads more development.
Great video as per usual. Also great sponsor. As a father of a six-year-old I can tell you these boxes are amazing. Not cheap but well worth it.
Excellent and innovative project!!
It needs a tail rotor, a slightly larger/thicker air container probably, and a full body clamping mechanism to hold it down while it builds air pressure. Then it will gain more RPM without tilting forward; and when it flies off into the sky on release, the body wont spin around in circles. Also i would experiment with a different main rotor that has higher mass and slightly lower thrust so it can store more energy and bleed it off over a longer period. Also probably needs a stronger air valve to handle the pressure being loaded into the bottle
Watching your videos keeps me reminding how amazing invention 3D printers are to hobbyists, can literally manufacturer on demand..!!
Completed project, partial projects, failed projects...post them all man. It is very enjoyable to watch the engineering process and be along for the ride. Great video
Hang the bottle vertically so it doesn't block the air flow off the prop and improves the tilting stability then two shorter booms to balance those arms with a fin to use downward air flow off the main rotor to counteract the torque, more torque more airflow etc.
For a given rotor thrust will go up by power^(2/3).
The momentum change of the air is mv. This equals force times time, so the force is equal to the mass of air you push per second times velocity. The kinetic energy added to the air you push is 1/2 m v^2. But doubling the velocity doubles the mass of air per second and the velocity, multiplying the energy owe second (power) by eight.
So multiplying power by x multiplies airflow by x^(1/3). Multiplying airflow by x^(1/3) multiplies thrust by x^(2/3).
