초록

Hydraulic power supplies for aircraft which have such hydraulically operated systems as flaps, ailerons, spoilers, rudders, elevators, brakes, and retractable and steerable landing gear. Typically, the aircraft will be of the multiengine type; and there will also be a multiplicity of hydraulic power supplies and engines. This scheme can be utilized to provide operating redundancy for the hydraulically operated devices of the aircraft. Each hydraulic power supply has a solid state controller which has a number of inputs as well as control and information ...

청구항

A hydraulic power supply for making pressurized hydraulic fluid available to one or more hydraulically operated devices, said power supply comprising: a pump means which provides pressurized hydraulic fluid for the operation of said device(s) and includes a first, engine driven pump and a second, demand pump which can be activated at the option of an operator and/or activated automatically upon a predicted increase in demand to prevent precipitous drops in the hydraulic fluid delivery pressure; a centralized solid state controller which: controls the ope...
