Abstract

The invention relates to an airplane hydraulic system layout based on a power-by-wire energy storage device. The layout comprises spoiler flap accumulators used for driving spoiler steering engines and flap steering engines, cabin door accumulators used for driving cabin door actuators, and empennage accumulators used for driving rudder steering engines and elevating rudder steering engines, wherein the spoiler flap accumulators, the cabin door accumulators and the empennage accumulators are all connected with a fly-by-wire operation system of an airplane and used for storing energy or acting based on output commands of the fly-by-wire operation system. By the adoption of the airplane hydraulic system layout based on the power-by-wire energy storage device, the 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 a power-by-wire energy storage device. 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 systems. They are respectively cal...
