The invention provides a bird-strike resistant aircraft external auxiliary fuel tank leading edge structure. The bird-strike resistant aircraft external auxiliary fuel tank leading edge structure comprises a fairing, a buffering baffle, a plug body, a front section skin I and a front section skin II, wherein the fairing is a variable-section thick wall structure; the front section skin I is connected with the fairing through a connecting piece so as to ensure that the assembling gradient between the front section skin I and the external surface of the fairing is less than 1 mm; and the buffering baffle is positioned behind the fairing and used for separating the front section skin I from the fairing so that fuels in the front section skin I and a rear structure of the front section skin I cannot enter the fairing. The invention is advantaged in that the structural design of the bird-strike resistant aircraft external auxiliary fuel tank leading edge structure is simple, and the bird-strike resistant aircraft external auxiliary fuel tank leading edge structure is very convenient to manufacture and assemble, can effectively resist flying bird strike and can also ensure that an auxiliary fuel tank cannot suffer a fuel leakage problem or a part fall-off problem to affect the flying safety of an aircraft.
