Abstract : An integrated roll control and power supply system for a missile includes a pair of flywheel-motor-generator (FMG) units, a pair of power flow control (PFC) units coupled between the FMG units and a missile load, and a roll sensor coupled to the PFC units. The integrated system also includes a pair of resistance heaters and a pair of clutch-brake devices. The FMG units are axially aligned and displaced from one another. One FMG unit operates in a counterclockwise direction, while the other FMG unit operates in a clockwise direction. The two FMG units produce the bi-directional roll torque characteristic necessary to develop roll-dampening torques for the missile system roll control autopilot. The PFC units receive roll attitude, rate and acceleration input signals from the roll sensor and, in response to such signals, are operable at three different levels of roll damping to dissipate power flow from the FMG units to supply electrical components of the missile and to operate resistance heaters and clutch/brake devices to develop appropriately balanced roll torques in the missile airframe.
