POWER SUPPLY SYSTEM OF STEERING DRIVES OF PRIMARY CONTROLS OF PASSENGER AIRCRAFT Russian patent published in 2016 - IPC B64C13/50 B64D41/00 H02J9/06 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to power supply control system for actuation of aircraft control surfaces. Power supply system of steering drives of primary controls of passenger aircraft includes onboard electric generators of alternating current, auxiliary electric generators of alternating current, electric generators control units, current transformers, main storage batteries, emergency batteries, rectifying devices, power supply control system, consisting of the central onboard computer and instrumentation and control devices. Rotors of onboard electric generators are connected with the rotors of sustainers. Rotors of auxiliary electric generators are connected with the rotors of auxiliary power plant and turbine unit. In power network of each steering gear of primary controls of aircraft the main storage batteries are connected, emergency batteries and the power supply control system is actuated. Input of instrumentation and control devices is connected to the input of steering drives, and the output - with emergency batteries and the central onboard computer, the output of which is connected to the inputs of instrumentation and control devices.

EFFECT: increase of in-flight safety in case of failure of all power sources.
