Research progress on impact resistance wing fuel tank cover

The wing fuel tank cover and its surrounding wing outer plate together form a part of the aircraft's aerodynamic shape. During the service process of an aircraft,the fuel tank cover is inevitably hit by foreign objects,ensuring the impact resistance of the fuel tank cover is of great significance for ensuring the safety of the aircraft. In this paper the research progress of impact resistance performance of wing fuel tank cover is systematically introduced from three aspects: airworthiness regulations requirements,common materials and structural forms,assessment methods and evaluation,the current research conclusions are summarized,and the future development of wing fuel tank cover is prospected. The research results can provide theoretical and technical references for the design and manufacturing of new types of masks in the future.
