I think we need a little more info, F18.

Are you planning on any type of throttle or just let the engine run at full speed? If no throttle, the pressurized tank should work. But as the tank pressure bleeds off the flow will be reduced and slow the engine. A regulator could be used to stabilize the flow and increase run time. In essence, over-pressurize the tank and use a flow/pressure regulator to supply a nice, steady state flow and pressure for a longer time.

Are you using a fuel injector or just an open atomization nozzle? The open nozzle gives no control, while an injector could be used for at least on/off to give a minimum of engine control.

On my auto fuel pump idea, I was thinking of a high pressure fuel injection pump. Yes, low pressure pumps for carbs do pulse, but the float and fuel bowl is the regulator, if you will. F. Inj. pumps don't have as much pulsation and aren't as noisy. I think a regulator would be helpful.

One problem with a pressurized tank is the natural bleed in pressure and you run out of pressure long before you run out of fuel. At least a pump will allow the use of a full tank of fuel.

To pressurize the tank, you could put a sharader valve (tire stem) in the tank and use one of the small 12 VDC air pumps to pump to just about any pressure you want. A bladder might be useful, too.

I asked about reduction for prop/rotar drive because I think you will be disappointed by the thrust developed. And I could very well be off-base on that.

Have fun and give your neighbors a six pack so they they don't complain too much about the noise.

Got oics?
