Problems solved by technology
[0002] Bird strikes mostly occur at the leading edge of the aircraft's wing, which seriously endangers the flight safety of the aircraft. It is difficult to ensure that the leading edge of the wing of the current aircraft can still complete the flight safely in the event of a bird strike. In addition, the current The leading edge of the wing of the aircraft lacks a corresponding drainage design, at least its interior is prone to water accumulation, which will adversely affect the flight of the aircraft

A leading edge structure of an airplane comprises a first skin and a second skin. The first skin is provide with a first skin first end, a first skin second end opposite to the first skin first end, afirst skin first edge extending between the first skin first end and the first skin second end, and a first skin second edge opposite to the first skin first edge. The first skin first edge and the first skin second edge are oppositely bent to form a first skin inner cavity. A laminated board at the sharp end of the first skin inner cavity is locally thickened. The second skin is provided with asecond skin first end, a second skin second end opposite to the second skin first end, a second skin first edge extending between the second skin first end and the second skin second end, and a secondskin second edge opposite to the second skin first edge. The second skin first edge and the second skin second edge are oppositely bent to form a second skin inner cavity. A laminated board at the sharp end of the second skin inner cavity is locally thickened.
Description
Technical field [0001] This application belongs to the field of aircraft leading edge structure design, and specifically relates to an aircraft leading edge structure. Background technique [0002] Bird strikes mostly occur on the leading edge of the wing of the aircraft, which seriously endangers the flight safety of the aircraft. At present, the leading edge of the wing of an aircraft can hardly guarantee that it can still complete the flight safely even if it is hit by a bird. The leading edge of the aircraft's wing lacks corresponding drainage design, at least it is easy to accumulate water inside, which will adversely affect the flight of the aircraft. [0003] This application is made in view of the above-mentioned shortcomings of the prior art. Summary of the invention [0004] The purpose of the present application is to provide a leading edge structure of an aircraft, so as to overcome or alleviate at least one of the defects of the prior art. [0005] The technical solutio...
