Hello everyone
For the past 2 years I have slowly and agonisingly tried to make a flight simulator in http://www.blender.org" . I've gotten as far as this (regarding physics):
- got the Lift and Drag calculations
- got the thrust calculations
- got some REALLY basic roll calculations.
It is the the steering physics and flight dynamics I need help with now. I read that ailerons cause roll by deflecting air in certain directions. This causes the net lift to change and makes the aircraft rotate around its longitudinal axis. So I've come up with a whole lot of calculations that calculate the lift on different parts of the wing and calculate the difference in lift, and then use that to create torque. This works. But as I know, this isn't the only variable in aircraft roll... I know inertia is another one, but not much else (http://en.wikipedia.org/wiki/Flight_dynamics). What I need is some very simple but applicable roll calculations that can be used. I'm assuming at the moment that the same calculations can be adapted to work for the elevators and rudder. And as a note I would like to say that I am an eleventh grader with some common sense (hopefully!).
My current resources are:

Thanks.
