A high-voltage, low-volume capacitor module, having a minimal amount of inherent stray inductance, and being configured so as to allow its integration into an electrical system in a manner which minimizes any stray inductance introduced by interconnection wiring. This is accomplished by integrating the capacitor into the bus bars of the voltage convertor, thereby eliminating the need for separate interconnecting wiring and reducing the overall amount of stray inductance evident within the system in which the capacitor is employed.

Integrated bus bar/multilayer ceramic capacitor module

This invention relates to transducers for indicating position. In particular, this invention relates to circuitry for accurately measuring either rotary or linear displacement of an inductive coupling member within a voltage displacement transformer (LVDT or RVDT).

Position transducer apparatus and associated circuitry including pulse

Engine management system

Trim signals are removed from the fuel control computers of aircraft propulsion engines to increase thrust upon detection of a predetermined difference between engine speeds.

Turbine engine thrust booster

A recuperated gas turbine engine fuel and guide vane control which controls fuel flow and guide vane position during engine idling and acceleration to minimize fuel consumption while providing fast acceleration for a ground vehicle.

Variable geometry gas turbine engine fuel and guide vane control

An electrohydraulic proportional actuator for converting an electrical input signal to proportional mechanical output. Fluid power may be derived from pressurized fuel or lubricating oil of an associated engine. The actuator may be used to drive any engine function requiring modulated control. The mechanical output is proportional to the electrical input. The actuator includes mechanical feedback to linearize the response function, thus eliminating the need for closed loop operation of the system in which the actuator is used. Both linear and rotary actuators are disclosed in various embodiments. Each type is capable of operation with either a proportional solenoid and valve or a force rebalance solenoid and valve.

Electrohydraulic proportional actuator apparatus

A fuel delivery system comprised of a differential having three associated shafts. A first shaft is rotated at a speed responsive to the engine speed and drives the differential. A second shaft is driven by the differential against a variable retarding torque, which torque varies the speed of the second shaft. A third shaft is driven by the differential and drives a variable speed, fixed displacement fuel pump at a speed responsive to the speed of the second shaft combined with the speed of the first shaft.
