% Size a reaction wheel using maneuver requirements. Type RWASizing for a demo of a 3U CubeSat going 5 deg/s and accelerating to that in 5 seconds. Momentum storage will also be a function of how much momentum you want to absorb from disturbances. The reaction wheel inertia is computed using a default angular rate for the wheel of 628 rad/s. Since version 2014.1. -------------------------------------------------------------------------- Form: [t, h, inrRWA] = RWASizing( inr, omega, omegaDot, omegaRWAMax ) -------------------------------------------------------------------------- ------ Inputs ------ inr (1,1) Spacecraft inertia (kg-m^2) omega (1,1) Angular rate (rad/s) omegaDot (1,1) Angular acceleration (rad/s^2) omegaRWAMax (1,1) Maximum angular rate (rad/s) ------- Outputs ------- t (1,1) Torque (Nm) h (1,1) Momentum storage (Nms) inrRWA (1,1) Inertia rwa --------------------------------------------------------------------------
