Problems solved by technology

[0002]According to the regional distribution characteristics of hydraulic actuating loads on the aircraft, a distributed hydraulic system is designed to provide hydraulic sources for each hydraulic actuating load. The distributed hydraulic system consists of multiple Each local hydraulic energy system mainly includes hydraulic oil tanks, hydraulic pumps, heat exchangers and other dispersed components. Pushing the piston to pressurize needs to occupy a large space resource on the aircraft. In addition, it has a large mass, which is not conducive to the current demand for aircraft weight reduction. It only has the function of oil storage and pressurization, and the functional integration is low.

Abstract

The invention belongs to the technical field of airplane local hydraulic energy system design, and particularly relates to an integrated hydraulic oil tank. The integrated hydraulic oil tank comprises a barrel, a piston, a gas-phase end plate, a corrugated pipe, an oil-phase end plate and a heat exchanger; the piston is arranged in the barrel and can axially slide along the barrel; the gas-phase end plate blocks one end of the barrel, and a gas cavity is formed between the gas-phase end plate and the piston; the corrugated pipe is arranged in the gas cavity, one end of the corrugated pipe is connected with the piston, the other end of the corrugated pipe is connected with the gas-phase end plate, and the corrugated pipe is filled with pressurized air; the oil-phase end plate blocks the other end of the barrel, and an oil cavity is formed between the oil-phase end plate and the piston; and the heat exchanger is arranged in the oil cavity and connected to the oil-phase end plate.

Description

technical field [0001] The application belongs to the technical field of aircraft local hydraulic energy system design, and in particular relates to an integrated hydraulic oil tank. Background technique [0002] According to the regional distribution characteristics of hydraulic actuating loads on the aircraft, a distributed hydraulic system is designed to provide hydraulic sources for each hydraulic actuating load. The distributed hydraulic system is composed of multiple dispersed local hydraulic energy systems. Each local hydraulic energy system It mainly includes hydraulic oil tank, hydraulic pump, heat exchanger and other dispersed components. The hydraulic oil tank is the largest part among them, and the piston rod is pushed axially to pressurize the piston, which needs to occupy a large space resource on the aircraft. , In addition, it has a large mass, which is not conducive to the current demand for aircraft weight reduction, and only has the function of fuel storag...
