Hello.
I'm an engineering student and I'm trying to build a reaction wheel to stabilize a structure attached to a parachute.
My questions are:
1 - Is there any software or website that I can simulate the moment of inertia of the complete structure?
2 - Help me if the reasoning is right:
For the structure not to rotate, the sum of moments must be equal to zero.
Therefore, equating the moments of inertia of the disk and the structure (with components such as battery, plate and other things...), we have that:
wheel acceleration * wheel moment of inertia = structure acceleration * structure moment of inertia
Is it so simple? Don't I need to consider the wind, for example?
Or not, just in the PID control part?
