Problems solved by technology

When the aircraft is in a special flight situation, there may be a continuous negative overload phenomenon, which will cause the fuel in the fuel tank to escape from the bottom of the tank under negative overload conditions. Because the aircraft fuel supply pump is generally installed at the base of the mailbox, the fuel supply pump suction port cannot touch the fuel. , the problem of unsustainable and stable fuel supply caused by negative overload will affect the flight safety of the aircraft

Embodiment Construction

[0014] The following will combine figure 1 , clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a specific embodiment of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] Such as figure 1 As shown, a fuel supply pump 1 is installed at the bottom of the aircraft fuel tank, and the fuel supply pump 1 supplies fuel to the aircraft engine through the fuel supply pipeline 2 . An auxiliary oil supply device 3 is connected in parallel in the middle of the oil supply pipeline 2 . The auxiliary oil supply device 3 is an automatic piston mechanism, including four parts: a piston 31 , a spring 32 , an auxiliary oil tank 33 and a limiter 34 . The limiter is a piston barrel, the pis...

Abstract

The invention provides an airplane negative overload auxiliary oil supply device. The airplane negative overload auxiliary oil supply device mainly comprises an oil supply pump (1), an oil supply pipeline (2) and an auxiliary oil supply device body (3). The oil supply pump (1) is connected with an oil outlet of an airplane oil tank; the oil supply pump (1) is connected with the aircraft engine through an oil supply pipeline (2), an opening of the oil supply pipeline (2) between the oil supply pump (1) and the aircraft engine is connected with the auxiliary oil supply device (3) in parallel, and the auxiliary oil supply device (3) comprises a piston (31), a spring (32), an auxiliary oil tank (33) and a limiter (34). When a certain negative overload occurs to the aircraft, the oil supply pump (1) cannot suck fuel from an aircraft fuel tank, and the auxiliary fuel supply device (3) works to supply fuel to an aircraft engine, so that the continuous flight requirement of the aircraft is met. The device is simple in structure and can meet the use requirements of the aircraft in a flight overload state.

Description

technical field [0001] The invention belongs to the field of aviation machinery control, in particular to an aircraft negative and overload auxiliary fuel supply device. Background technique [0002] The safe flight of an aircraft requires a continuous and stable fuel supply to the engine. When the aircraft is in a special flight situation, there may be a continuous negative overload phenomenon, which will cause the fuel in the fuel tank to escape from the bottom of the tank under the negative overload condition. Because the aircraft fuel pump is generally installed at the base of the tank, the fuel supply pump suction port cannot touch the fuel. , the problem of unsustainable and stable fuel supply caused by negative overload will affect the flight safety of the aircraft. Contents of the invention [0003] In order to solve the above-mentioned deficiencies in the prior art, the technical problem solved by the present invention is to provide an auxiliary fuel supply devic...
