I absolutely loathe it. You cannot power anything with this. It is completely impractical. Compressed air systems are very heavy and very inefficient. He's practically cheating by using a pop bottle. Even a small RC race car would need a MUCH, MUCH heavier bottle to carry significantly more air. Air compressors are quite inefficient as are most air tools. This is why they have been almost universally swapped out in auto mechanics, for example. There are still a lot in industrial use though. There are lots of good reasons they are. But energy inefficiency isn't one of them.

@remijio303 22 дня назад

Where air isn't being blown through the turbine, the turbine is acting as a fan which is wasting energy. If you block 90% or so of the turbine where there's no compressed air blowing through it, it won't waste as much energy. It's the same as if you block a hoover, it uses less power so it spins up faster.

@cademckee7276 22 дня назад

That and some shrouding around the nozzle to ensure the air can’t escape/be redirected at the higher speeds.

@ThreeAngrySquirrels 22 дня назад

Also the outer shell rotating is creating a ton of surface drag. Need to switch to a static duct.

@kaing5074 22 дня назад

It also should be a one-way gear mesh that as the turbine slows it decouples from the flywheel, which means that its slowdown does not affect the power. Only energy in, and no added friction after the air pressure is too low.

@kaing5074 22 дня назад

Front wheels should also be tiny, and the bottle can be heatshrunk or a 2l vessel could be formed to be more aerodynamic. The bottle shape is not good and the front wheels are not helping with the rotational mass. The wheels should therefore be driven via a centrally mounted hub and with two sockets in order to reduce torque steer. To further reduce issues with the turbine, the fins should only be shaped like the water ones to redirect the air 180° and only on the rim say 1/2cm or less, so a cup or two cups per 'fin' a la water turbine blades and smaller. An additional ring made of metal could therefore be attached to the flywheel to balance it and add additional mass. But it definitely needs a central vertical position with a properly straight axle for both itself and the rear wheels to work. This wobbly jank is fine for a first concept but at high rpms there's not much room for error

@nanaki-seto 22 дня назад

You could drill out the end of a mini propane tank a 1 pounder and replace the normal valve head with a regulator that screwed on and not need to worry about it blowing up from dry ice. Soda bottle can hit 100psi+ with out exploding and 1 pound propane tank can get close to if not above 2k psi. Also water is not needed for dry ice to do it's thing it will sublimate just fine with out it

@kameljoe21 22 дня назад

@@nanaki-seto You do not need to drill a 1 lbs propane tank. Just buy the required fitting. They are super simple designs. Pretty sure propane tanks are tested at 600 psi from the factory.

@notconnected3815 22 дня назад

Yes, it's true. Pneumatic Cylinders are widely used in the industry. They have some (small) ambitions to replace them with electric actuators. But electric actuators are many times more expensive in the purchase. And Pneumatic is simple and robust in operating and maintaining. That's why they stick with pneumatic. A big part of the losses occur at the compressor in the form of excessive heat within the compressed air. As it cools down it looses energy. Some manufacturers store the excessive heat in paraffin, which heats up the air as it expands, giving some of the energy back to the working gas. So, there is potential ... Maybe Tom find's some clever ways to improve the overall efficiency ;-)

I've done similar experiments w an air nozzle blowing against blades. I discovered that changing the angle of the nozzle to the blades based on the wheel/blades RPM has benefits. One angle for high torque/ low rpm, then changing the angle as it spins to more of a tangent for higher rpm. Also, I've found that the plastic soda bottles can hold up to 150psi, then regulate down to the usable psi.

If the nozzles were staged it could dramatically increase efficiency. Have three nozzles. Use one very small nozzle as the low throttle. Don't open the second until the first is fully opened, then start opening the second, and so on. Partially opened valves are very inefficient. Having one valve fully opened with two others shut is a much better way to do 1/3 throttle vs 1 valve 1/3 open.

An axial turbine with multiple nozzles and stages would be the way to go; which looks like it's on the drawing board. See also my comment about incorporating the throttling valve into the nozzle design.

@derhugo0135 22 дня назад

Great video, and very neat concept. This reminds me of the "Turbonique" drag-axles that were a thing in the american drag-racing scene back in the 60s. They were essencially a turbine wheel, driven by a hypergolic fuel, integrated into the rear axle of the car, instead of having a traditional powertrain to drive the rear wheels. Maybe something similar is possible on an RC scale, similar to pyrotechnic starters on early jet engines with a solid rocket motor.

@BEdwardStover 19 дней назад

You don't want to exhaust your turbine near the center. You want the opposite, intake near center and exhaust on the outside edge. Then centrifugal force will help speed the air out, allowing you to maximize the power output. No idea if this is better than the other designs, I just know you did that 4 watt turbine backwards, making it work against centrifugal force as it spins up. It may be worth a try.

For pressing bearings: ALWAYS apply the force to the parts that is friction fitted. So if you pressing it on a axle apply the pressing pressure to the inner race and as you might guess if you're pressing the bearing into a bearing holder, apply the pressing pressure to the outer race. Unless you have a bearing designed (trust bearing, conical bearing) for it, they can't take much sideways forces. And it's easy enough to turn/3d print a tool for that.

@feha92 21 день назад

8:00 I think the reason the others performed better, is because the "curve" of the regular turbine's paths actually guide the air to exit in the opposite direction (so the force the air exits with, is additionally imparted to the turbine as a reactive force by Newtons laws. In addition to the energy you would get from completely stalling the air by absorbing 100% of the kinetic energy. So in total the theoretical maximum efficiency instead becomes 200% - and more if you can speed the air up! Minus of course any energy that was in the same axis as the spin-axis, since that direction was not touched), while the bad turbine only guides it to exit in a perpendicular direction (it absorbs all kinetic force in the axis perpendicular to spin-axis, but no more). It is much like how a gravity-powered generator at 100% efficiency has the weight not fall at all, while at 200% the weight start flying up into space! ;)

On a gasturbine you have a static ring with blades that get the air to „spinn“ and push the blades on the moving wheel. The blades on the moving wheel „straighten“ the airflow. If you have a multistage turbine the next static ring will to the same until there is no pressuredifference left. So maybe instead of blowing at the moving ring with a nozzle using a distibuting chamber and a static ring might help.

A point on the tyres - the amount of grip is relative to the amount of load forcing those tyres into the ground. You got a tiny bit of slip on the launch so it might be worth either adjusting the weight bias or adding a bit of ballast over the rear axle to maximise the amount of force you can generate

You are currently using an axial flow compressor style, which works great for acceleration of large amounts off air, hence why jet turbines use them, instead I would recommend looking into centrifugal flow compressors these are what are used in anything from large generators to helicopters and turbo prop aircraft, as they are much better for high torque applications. Love the project and can’t wait to see where you will go with it!

Really cool how at 6:06 you can see when the pressure drops on the bottle the bottle gets foggy because the water is vaporizing

The problem is not only the input air expanding, its also the already existing air putting drag on the turbines.. by being chaotic. What you want, is an enclosure for the turbine, that allows a vortex to form that goes into the same direction and keeps the air that follows up directional aligned with the running turbine. That way, you also decrease the slowing down low-pressure pockets and ideally, the small sub vortexes shedding from the tip of the blade..

Sounds phenomenal

Dude the sound of the turbine spooling up terrifies me

@gstpierre69 22 дня назад

Use buckets after the nozzle that basically reverse the flow back into the turbine. Simple 1 stage turbines often have a couple of these.

It's amazing to use compressed air to rotate a complete model turbine. Thank you

Just remember, if you want to beat world record you have to dtart from second gear. That is the storry bro!

I feel like if the power goes in both of the rear wheels, the speed and steering would be better. Maybe like 2 turbines from the same bottle (which would drain air faster) or a differential to drive both wheels

Meester Tom sir guy man, if you want to reduce wheel mass, there is the sponge/foam tyre option. You can make your own light as comfortable wheels and stretch on a foam ring of grippiness. Can texture the circumference of the wheel to reduce any material slippage.

The little Hoosier tires cracked me up.

Perhaps two nozzles and turbines in parallel. One with large surface area and one with small. The large generates higher thrust but low speed for the initial phase of acceleration. At a certain speed they switch so you get higher top speed with lower consumption.
