Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I am hoping to build a model rocket with a roll control system for my senior project. Since the idea of building or obtaining a wind tunnel seems infeasible I will need to theoretically calculate how this rocket will behave with various canard fin angles and at various air speeds. I assume first I will need to measure the moment of inertia of the rocket airframe. Can someone give me an idea of how to do this? I assume somehow I would mount the rocket to some type of rod (which itself doesn't significantly affect the moment of inertia) and measure the angular acceleration as a function of torque, right? So I would need some type of gyro or accelerometer and a torque transdicer of some kind, right? Can someone help me out here?

Also, I would need to be able to determine how much torque is applied to the rocket airframe at different airspeeds and different fin angles. Can someone help me with this?
