Problems solved by technology

Due to the characteristics of large dynamic load and high opening speed during the opening process of the hatch, the installed power of the hydraulic drive system for opening the hatch is particularly large, which in turn makes the installed power of the matching main engine hydraulic system very large, increasing the load on the engine and the aircraft. weight

Abstract

The invention relates to a new-principle cabin door transient actuating system based on a variable displacement motor. The system comprises a variable displacement motor, a hydraulic pump, an energy accumulator and a control valve, wherein the variable displacement motor is connected with the hydraulic pump and used for driving the hydraulic pump; the hydraulic pump comprises an oil outlet and an oil inlet, the oil outlet is connected with a first input end of the control valve, the oil inlet is connected with a second input end of the control valve; the energy accumulator is connected to an oil way between the oil outlet and the first input end; and when the pressure difference between the first input end and the second input end is greater than a preset value, the control valve is started. By adopting the new-principle cabin door transient actuating system based on a variable displacement motor, the installed power of the hydraulic system of an airplane can be reduced, and further the airplane weight is lightened and oil consumption is reduced.

Description

technical field [0001] The application relates to the field of hydraulic systems, in particular to a new principle cabin door transient actuation system based on variable motors. Background technique [0002] Due to the need for stealth and reduced drag, the buried layout of the bomb bay has been widely used by new fighters. [0003] At present, the drive mode of the bomb bay door adopted at home and abroad is that the hydraulic system of the main engine directly supplies oil to the hydraulic motor, and the output torque of the driving motor drives the door to rotate and open after being decelerated. Due to the characteristics of large dynamic load and high opening speed during the opening process of the hatch, the installed power of the hydraulic drive system for opening the hatch is particularly large, which in turn makes the installed power of the matching main engine hydraulic system very large, increasing the load on the engine and the aircraft. weight. [0004] In or...
