I did some rough calculation.
E(Engine Force). = 800 N
m(Mass of reaction wheel) = 10 kg
r(radius of reaction wheel) = 0.2 m
w(max spin rate of wheel) = 6000rpm * 2pi / 60s
cgo(C.G offset) = 0.01m
I = m * r * r / 2 = 0.2 kgm^2
WheelCapacity = I * w = 125.6 Nms
Torque experienced during engine firing due ...
