  • @Matmamtmamtmamtmamtm
    @Matmamtmamtmamtmamtm 3 года назад +7

    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

  • @nathanjohnson83
    @nathanjohnson83 3 года назад +20

    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 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.

      @@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.

    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.

    In 100 years, when we're flying our personal compressed air helicopters, we'll be able to say we watched the pioneer making baby steps in this revolutionary part of aviation.

    I feel like we're about 2 years away from a "1:1 scale fully operational sherman tank powered by compressed air" video

    This guy took a water bottle and made it actually useful. I can’t even think of doing that. You always have outstanding ideas EVERY week or day

    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!

    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. 🤣

    Something I learned from the video:
    Tractor tires are meant to spin at 5000RPM and a Formula 1 doesn't provide enough power.

    That wasn’t a failure. You managed to make a helicopter that runs on compressed air. Great job.

    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

    The sun, a window and a wall is an easy way to see air flows in real time. No camera required
