Integrated roll control and power supply system and method

An integrated roll control and power supply system for a missile, comprising:

• (a) a pair of flywheel-motor-generator (FMG) units being axially aligned with one another and respectively operable in clockwise and counterclockwise directions so as to produce bi-directional roll torque and generate electrical power;
• (b) means for sensing roll accelerations in clockwise and counterclockwise directions in an airframe of a missile and being operable to generate output signals corresponding thereto;
• (c) a pair of power flow control (PFC) units connected to said roll sensor and coupled between said FMG units and an electrical load in the missile, said PFC units also being coupled between said FMG units and said first and second dissipating means, said PFC units being operable to receive said output signals from said roll sensor and to cause selected dissipation of the roll torque of said FMG units by supplying electrical power from the FMG units to the electrical load in the missile and to said first and second dissipating means and thereby produce roll-damping torques in the airframe for control of any undesirable roll in the airframe of the missile;
• (d) first and second means coupled to said PFC units for receiving electrical power from said PFC units and dissipating said electrical power as heat;
• and
• (e) a first and second means coupled to the power flow control units for transferring energy directly between the two FMG units.

An integrated roll control and power supply method for a missile, comprising the steps of:

• (a) providing on an airframe of a missile a pair of flywheel-motor-generator (FMG) units being axially aligned with one another and respectively operable in clockwise and counterclockwise directions so as to produce bi-directional roll torque and generate electrical power;
• (b) sensing roll accelerations in clockwise and counterclockwise directions in an airframe of a missile and generating output signals corresponding thereto;
• (c) in response to said output signals, causing selected dissipation of the roll torque of said FMG units by supplying electrical power from the FMG units to the electrical load in the missile and thereby producing roll-damping torques in the airframe for control of any undesirable roll in the airframe of the missile;
• and
• (d) in response to said output signals, transferring electrical power as needed from one FMG unit to the other FMG unit.
