- Rocket maximum revolution rate
- Rocket moment of inertia
Formulas in parens aren't finished.
Conservation of angular momentum gives that Irwr + Iwww = 0, which can be rearranged to say that (Iw / Ir = wr / ww), to find the rotational inertia the wheel should have, knowing the rocket's and wheel's maximum revolution rates, and the rocket's moment of inertia. However, the rocket's moment of inertia is relatively harder to measure, so the mass can be used to approximate.
