Question on ventilation in small aircraft
I'm working on adding some ventilation effects in my single seater cockpit. Basically two electric fans blowing your face and body that are speed controlled via software. Currently I can mix engine RPM and airspeed to control the fans. Some first results are described at http://www.simprojects.nl/wind_in_your_face.htm
Maybe I'm way off in my assumptions, so I would appreciate if someone could give me some info on how the actual ventilation in Cessna type of aircraft works and feels during engine start, take-off and flight. As far as I know, the ventilation intake is on the left and right top sides, at the wing front. I don't know how the engine RPM affects this air intake, and whether there are other areas in the cockpit that give you hints of engine and airspeed related ventilation effects.
Thanks!
