A multi-stage pilot valve is disclosed for selectively supplying a working fluid to and venting from a reaction jet main stage actuation chamber. In a preferred embodiment of the invention, the pilot valve comprises a solenoid actuated ball and socket flapper valve having a pressure inlet, an exhaust outlet and a service port. The first stage service port is in fluid communication with a second stage actuation chamber. A piston disposed in the second stage actuation chamber operatively engages a ball member of a ball-and-seat type valve comprising the second stage valve. The second stage valve also comprises a pressure inlet, an exhaust outlet and a service port. The piston and ball are sized relative to each other such that when the second stage actuation chamber is pressurized by the first stage, the force is sufficient to seat the ball against the second stage pressure inlet. This shuts off the flow of high pressure gases to the second stage service port and permits the second stage service port to vent through the exhaust port. When the second stage actuation chamber is vented by the first stage valve, the pressure acting on the ball is sufficient to seat the ball against the second stage exhaust outlet.

An active magnetic bearing assembly includes at least two rotors and two stator assemblies each having two pole faces. The pole faces of the stator assemblies are axially offset from the pole faces of their associated rotors. Thus, axial control of a shaft that is rotationally mounted using the active magnetic bearing assembly is provided by a reluctance centering force.

A system and method for controlling an active magnetic bearing assembly by varying the system control laws in a continuous non-linear fashion as a function of rotor rotational speed. The system control law variation is carried out in a continuous and optimal manner over the operating speed range of the rotor, and is not computationally intensive.

An integrated power and attitude control system that includes a plurality of flywheels and a controller. The controller receives power commands and attitude commands and determines the optimum set of flywheel acceleration and gimbal velocity commands to supply to each flywheel, to meet the commanded power and attitude. Flywheel rotational acceleration is controlled to provide the commanded power, and both flywheel acceleration and flywheel gimbal angular velocity are controlled to provide the commanded attitude.

A prognostic health and fault management system and method that accurately determines the health and rate of degradation of one or more flywheel systems, by comparing actual and simulated responses of flywheel systems to supplied command signals. Based on the determined health status and degradation rate of the flywheel systems, one or more unhealthy, active flywheel systems are deactivated, and one or more healthy, deactivated flywheel systems are activated. The system can be used in terrestrial applications, or in vehicles such as satellites, spacecraft, or ships.

A digital filter and filtering method uses a rate of change limit and an acceleration limit to significantly attenuate high bandwidth noise signals with minimal phase lag, while simultaneously passing low bandwidth signals substantially uncorrupted. The filter uses two memory states making it computationally efficient.

A vehicle, such as a missile, with a pilot valve system controls the vehicle's thrust valves despite a hostile propellant gas environment. The pilot valve system can have one or more pilot valves. Using refractory elements, the pilot valve ball reciprocates between a supply seat and a vent seat which is subject to the filtered inflow of propellant thrust gases. When open, the pilot valve allows the stray thrust gas to communicate to a control chamber which closes a poppet against a valve seat in the nozzle. When an associated solenoid closes the pilot valve by pushing the pilot valve ball against the supply seat, the control chamber is vented to ambient. The poppet may then travel into the cylinder bore and the nozzle is opened to exhaust propellant gases and exert lateral thrust on the vehicle. Certain nozzle thrust geometries provide useful vehicle guidance.

A system for regulating the voltage in an electrical distribution system includes a plurality of flywheels, motor/generators, and controllers. Each of the motor/generators is coupled to one of the energy storage flywheels and to the electrical supply system. The motor/generators each supply one or more signals representative of motor/generator operational parameters, and each motor/generator controllers receive one or more of the motor/generator operational parameter signals from each of the motor/generators. In response to the operational parameter signals, the motor/generator controllers each control the operation of one of the motor/generators in either a motor mode or a generate mode, to thereby regulate the electrical supply system voltage and equally share the electrical load between the motor/generators.
