hey thanks, umm, I am am designing an R/C plane with a turbofan engine, however i was hoping to make the engine completely electronic so that i don't waste all my money on fuel. The problem is that i don't know the formulae to find out if it can produce enough thrust to move.
This is just an add on, if i was to make an A/C generator and attach it to the turbine shaft, is it possible that i can run the whole thing without combustion off the gen? I also was wondering if i could use ram air to increase pressure in the middle to replace the combustion chamber and also...
Can anyone tell me some formulae that i can use for finding the thrust in a remote control turbojet engine if the area of the intake is 196.35cm square and the exhaust is 78.5cm square and the pressure increases by 31 times?
