Abstract

The embodiment of the invention provides a fuel tank for a fixed-wing aircraft. The fuel tank comprises a first-section shell, a second-section shell connected with the first-section shell in an inserted mode, and a third-section shell connected with the second-section shell in an inserted manner; the first-section shell is sealed in a radial direction and connected with the second-section shell in an inserted mode through a first butt joint frame; and the second-section shell is sealed in a radial direction and connected with the third-section shell in an inserted mode through a second butt joint frame. The fuel tank for the fixed-wing aircraft is high in overall rigidity and light in weight.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a fuel tank for fixed-wing aircraft. Background technique [0002] The auxiliary fuel tank refers to the fuel tank with a thick middle and streamlined ends hanging under the fuselage or wing of the spacecraft. Hanging the auxiliary fuel tank can increase the range and endurance of the aircraft, and the aircraft can throw away the auxiliary fuel tank when necessary in air combat, and enter the battle with better maneuverability. [0003] Except for the non-disposable auxiliary fuel tank designed to match the shape of the fuselage in the early days, the main design direction of the external fuel tank is streamlined, in order to reduce the drag generated, which has a negative impact on the aircraft's mobility and stability. , to reduce the impact on other carrying equipment or the fuselage structure when it is separated from the aircraft. Some auxiliary fuel tanks have a small fi...
