Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an aircraft fuel tank that can automatically adjust the temperature of the tank body, which solves the problem that the aircraft is prone to freeze the fuel in a low-temperature environment, and even freezes the fuel tank. Higher, the more volatilization of fuel, if the temperature of the fuel tank continues to be high, it will cause the fuel to burn on the surface of the fuel tank and cause the problem of aircraft failure

Embodiment Construction

[0024] In order to better understand the present invention, the implementation manner of the present invention will be explained in detail below in conjunction with the accompanying drawings.

[0025] Such as Figure 1-6 As shown, the present invention provides a technical solution: an aircraft fuel tank that can automatically adjust the temperature of the tank, including a housing 18, the lower surface of the housing 18 is fixedly connected to the upper surface of the bottom plate 1, and the upper surface of the housing 18 It communicates with the lower end of the feed port 5, and a supercharger 4 is fixedly connected to the upper surface of the housing 18. By setting the supercharger 4, the staff uses the supercharger 4 to pressurize the inside of the housing 18 to make the housing The pressure in the body 18 increases, so that the liquid nitrogen is discharged through the drainage pipe 7, and enters the sealed box 13 through the connecting pipe 8. The left side of the casin...

Abstract

The invention discloses an aircraft fuel tank capable of automatically adjusting the temperature of a tank, relating to the technical field of aircraft fuel tanks, include a housing, the lower surfaceof the shell is fixedly connected with the upper surface of the bottom plate, The upper surface of the shell is communicated with the lower end of the feeding port, and the upper surface of the shellis fixedly connected with a supercharger. The left side of the shell is provided with a supercharger valve and a pressure reducing valve, and the supercharger valve is positioned above the pressure reducing valve, and the left side of the shell is provided with a safety valve, and the safety valve is positioned above the supercharger valve. Which can automatically adjust the temperature of the tank, through the booster valve, Pressure relief valve, turbocharger, Liquid nitrogen tank, vacuum layer, valve, vacuum layer, conduit and sealed tank cooperate with each other. When liquid nitrogen changes from liquid to gas in vacuum layer, it will absorb heat from the surface of fuel tank body, and nitrogen gas will be discharged from the valve to take away heat from the surface of fuel tank body, so as to regulate the temperature of fuel tank body, thus ensuring that the fuel tank body of aircraft is not affected by external temperature.

Description

technical field [0001] The invention relates to the technical field of aircraft fuel tanks, in particular to an aircraft fuel tank that can automatically adjust the temperature of the tank body. Background technique [0002] Usually the aircraft has three fuel tanks, the central fuel tank and the left and right fuel tanks. A small number of aircraft also have a trim fuel tank at the tail, and the pitch attitude of the aircraft is adjusted by adding fuel to the trim fuel tank at the tail. The fighter will also have auxiliary fuel tanks, which are divided into disposable and non-disposable. [0003] Aircraft fuel tanks store enough energy for the aircraft to last. However, due to the long winter in some areas and the cold climate, the aircraft is prone to freeze the fuel in low-temperature environments, and even crack the fuel tank, making it unusable. If the fuel with antifreeze function is used, it will Greatly increase the transportation cost of the aircraft. When the air...
