Abstract

The invention relates to an airplane hydraulic system layout based on hydraulic and power-by-wire boosting and energy storing devices. The airplane hydraulic system layout based on the hydraulic and power-by-wire boosting and energy storing devices comprises a spoiler and aileron energy storing device, a cabin door energy storing device and an empennage energy storing device, wherein the spoiler and aileron energy storing device is used for driving a spoiler steering engine and an aileron steering engine; the cabin door energy storing device is used for driving a cabin door actuator; the empennage energy storing device is used for respectively driving a rudder steering engine and an elevator steering engine; the spoiler and aileron energy storing device and the cabin door energy storing device are connected with an engine driving pump, and are used for receiving oil pressure input from the engine driving pump; and the empennage energy storing device is connected with a power-by-wire control system of an airplane, and is used for storing energy or actuating on the basis of an output instruction of the power-by-wire control system. By the airplane hydraulic system layout based on the hydraulic and power-by-wire boosting and energy storing devices, installed power of the airplane can be reduced.

Description

technical field [0001] The present application relates to the field of hydraulic systems, in particular to an aircraft hydraulic system layout based on hydraulic pressure and power transmission boost energy storage devices. Background technique [0002] The aircraft hydraulic system is one of the main onboard systems of the aircraft. The control and actuators of the main control system and auxiliary control system of modern aircraft use hydraulic pressure as the energy source, and hydraulic actuators or hydraulic motors as the actuators. The aircraft hydraulic system refers to the complete set of devices on the aircraft that use oil as the working medium and rely on oil pressure to drive the actuator to complete specific manipulation actions. In order to ensure the reliability of the hydraulic system, especially to improve the reliability of the hydraulic power source of the flight control system, most modern aircraft are equipped with two (or more) independent hydraulic sy...
