Embodiment Construction

[0032] The fuel system consists of a fuel tank 1, a dual-channel pipeline 2, a bleed air connection pipe 3, a fuel supply connection pipe 4, and a channel separator 5.

[0033] Component function: fuel tank 1 realizes fuel loading; dual-channel pipeline 2 realizes the introduction of engine bleed air into fuel tank 1 and fuel tank 1 to the engine; fuel tank 1 is equipped with a sealed partition for pressurized gas passage The pressurized air enters the top of the fuel tank to pressurize the fuel in the fuel tank; the channel separator 5 realizes the separation of the oil and gas medium pipelines in the dual channel pipeline 2, and is connected to the engine through the bleed air connecting pipe 3 and the fuel supply connecting pipe 4 The air outlet is connected to the fuel inlet, and a pressure reducing valve is installed in the channel separator 5 to achieve engine bleed air pressure reduction and meet the fuel boost pressure requirement.

Abstract

The invention provides an aircraft fuel system. The aircraft fuel system is characterized in that the aircraft fuel system comprises a fuel tank (1), a double-channel pipeline (2), an air entraining connecting pipe (3), an oil supplying connecting pipe (4) and a channel separator (5), the fuel tank (1) comprises a sealing partition channel (8) located at the periphery and an fuel tank body (15), and an air hole (9) is formed in the lower surface of the sealing partition channel (8) on the upper portion of the fuel tank body (15); and the double-channel pipeline (2) comprises an inner pipe (6)and an outer pipe (7), the inner pipe (6) penetrates into the outer pipe (7), the inner pipe (6) and the outer pipe (7) are sealed mutually, the inner pipe (6) is a hose, and the outer pipe (7) is a hard pipe or a hose.

Description

Technical field [0001] The invention relates to the field of aircraft fuel systems, in particular to small aircraft fuel systems. Background technique [0002] The function of the aircraft fuel system is to store fuel and deliver it to the engine. The fuel system of a large aircraft has a complex structure and numerous pipelines, but due to its large space, the installation and maintenance conditions are better; for small aircraft, due to space constraints, more system pipelines cause troubles in the installation and maintenance of the fuel system. , Due to the low-cost design concept, its safety is not high. The fuel system of the present invention has a simple structure, is easy to install and maintain, has good safety and reliability, solves the above problems, and has extremely high engineering application value. Summary of the invention [0003] The purpose of the present invention: [0004] The invention aims to improve the installation and maintenance performance of the fu...
