Abstract

The invention discloses an auxiliary fuel tank capable of preventing bird impact, belonging to the technical field of aircraft fuel tank protection. A buffer layer is arranged at the head of the auxiliary fuel tank, the buffer layer is positioned in the auxiliary fuel tank and is connected with the skin at the head of the auxiliary fuel tank by virtue of a fastener, and a safe distance is reserved between the buffer layer and the skin. The auxiliary fuel tank capable of preventing bird impact is characterized in that on the basis of not changing the pneumatic shape of the auxiliary fuel tank, the buffer layer is additionally arranged at the head of the fuel tank, so that enough strength of the fuel tank is ensured, and meanwhile, the auxiliary fuel tank can be sealed so as to prevent the occurrence of fuel leak caused by the bird impact phenomenon.

Description

technical field [0001] The invention belongs to the technical field of aircraft fuel tank protection, and in particular relates to an anti-bird collision auxiliary fuel tank. Background technique [0002] When the aircraft is in flight, if the external auxiliary fuel tank is hit by a bird, damage to the auxiliary fuel tank, fuel leakage, etc. may occur and affect the safety of the aircraft. [0003] When a bird strike occurs, the front edge structure of the external auxiliary fuel tank is hit first. In order to meet the flight safety requirements of the aircraft, it is necessary to design a new type of external auxiliary fuel tank that can resist the impact of flying birds. [0004] In the prior art, a protective structure is added to the auxiliary fuel tank of the aircraft, which changes the overall aerodynamic shape of the fuel tank of the aircraft, and has high requirements for installation and sealing, which may easily cause fuel leakage.
