Question 10.7: A spacecraft of mass m and with the dimensions shown in Figu...
A spacecraft of mass m and with the dimensions shown in Figure 10.15 is spinning without precession at the rate ω_{0} about the z axis of the principal body frame. At the instant shown in part (a) of the figure, the spacecraft initiates a coning maneuver to swing its spin axis through 90°, so that at the end of the maneuver the vehicle is oriented as illustrated in Figure 10.15 (b). Calculate the total delta-H required, and compare it with that required for the same reorientation without coning. Motion is to be controlled exclusively by the pairs of attitude thrusters shown, all of which have identical thrust T.
