Prop Model Airplane
What will be increase in speed if jet of compressed air is used instead of a propl plane ?
I wish to make a battery driven aeroplane.One model of a typical prop. plane's data :75 kg. payload, 150 kg. gross wt. including everything. power : 18 hp gives max. 195 kmph speed.If I use electric motors of 18 hp to compress air instead of driving a propeller and exhausts the air as a jet ( without adding any fossil fuel ) i.e. without any combustion :1. can this plane fly ?2. What will be gain in speed ( jet of compressed air instead of propeller ?
1a) This is a theoretical question, since we don't know the design of the aircraft.
1b) You won't be able to get the aircraft to fly. There are too many levels of power loss. And even if you did manage to get it off the ground - it will be a rocket, not an airplane. My guess is that you will not find a compressor small and efficient enough to put the aircraft in flight.
2a) Engine performance totally depends on energy vs weight. The higher the compression, and the rate at which the air is released (nozzle size) are factors. You'd be better off using a compressor on the ground, filling a small tank, and using no engine in the aircraft. Even then, your flying time will certainly be less than if you just used a electric propeller engine.
2b) The compressor has (very small) inducted fans. How fast must these fans spin if they were mounted at the front of the aircraft? Assuming that the compressor engine was perfectly efficient (none are) this is exactly how much energy it would require to get the aircraft to fly at the equivalent propeller-dirven speed.
I don't think it's very realistic. Better to just compress the air on the ground, then carry the air.... into the air.

Propeller Powered Skateboard - Test Day!
Tommy Boy is the best.
Tommy:"Hey, I'll tell you what. You can get a good look at a butcher's a$$ by sticking your head up there. But, wouldn't you rather to take his word for it?"
Richard: "Housekeeping. You want mint for pillow?"
Tommy: "Please go away let me sleep, for the love of God."
Richard: "Housekeeping. You want me to jerk you off?"
Tommy: "What kind of hotel is this?"
[opens door]
Tommy: "Who the hell are… Oh, it's you"
Richard: "Good morning, sunshine"
I also liked Black Sheep, another movie starring him and David Spade:
David Spade (Steve Dodds): "you ok?"
Chris Farley (Mike Donnelly): " I'm just dandy, I got a bowl of chocolate pudding in my underpants"
David Spade:" we didn't have any chocolate pudding in there buddy " LOL
Edit: Oh I also started watching Almost Heroes with Chris and Matthew Perry a couple days ago but I haven't finished it yet. So far so good
