Abstract
A momentum wheel (14, 142) for compensating for the adverse effects of disturbing torques on stabilized spacecraft is mounted on a base (12, 124) on the spacecraft by three circumferentially spaced supports which include at least two linear actuators (26, 118) that tilt the wheel (14, 142) in any desired direction. One end of each actuator (26) is mounted to a base (38, 154) supporting the wheel by a spherical connection (32, 34, 36) which allows freedom of motion about multiple axes. The other end of each actuator (26) is mounted to the base (12) by either a pair of spaced hinges (22, 24, 46) and a support bracket (18) which is secured to the actuator (26) or a flexible bracket (78). The wheel base (12,124) may also be mounted on the actuators by flexible members (150) which allow tilting of the wheel.
