I like the idea of compressed gas for the pre-rotar! That might be do very
able... "sanman" wrote in message om... Hi, I'd done some reading about pre-rotators for gyroplanes which can be used to give them a jump takeoff. I was wondering if any of them have tried using compressed gas to power the pre-rotator? I got the idea after reading these links: http://www.howstuffworks.com/question133.htm http://news.bbc.co.uk/1/hi/world/africa/988265.stm http://auto.howstuffworks.com/air-car.htm http://www.evworld.com/databases/sho...=news190503-04 Gee, now that I think about it, why couldn't compressed air even be used to power the gyroplane pusher prop during regular flight? An onboard compressor could even be used to compress air into the cylinder in the first place. Liquified nitrogen gas can store a lot of energy, pressure-wise -- more so than what a battery could store. That compressor could be reversible as a motor.
