Research on Guillotine Test of Fuselage Fuel Hose of Civil Aircraft Auxiliary Fuel System

If the fuel Hose in the fuselage of a civil aircraft is damaged in a survivable crash accident, the fuel leaked from the fuselage fuel pipe may cause an uncontrollable fire. The guillotine test is a test to verify the deformation and tension capability that the fuselage fuel pipe should remain free of oil leakage. However, different aircraft have different configuration and layout, and the structure in the fuselage and other system equipment are very complex, it is very difficult for the airworthiness authority to formulate unified verification test requirements. Considering that the guillotine test is one of the large-scale compliance verification tests perplexing the civil aviation field at home and abroad, this paper studies the guillotine test of the fuselage fuel hose of a domestic civil aircraft auxiliary fuel system, so as to provide a reference for the guillotine test of the fuselage fuel hose of civil aircraft at home and abroad.
