| Abstract: |
| The paper aims to provide reference for design of wing leading edge by simulating, testing and comparing six kinds of wing leading edges. With the leading edge of a certain aircraft wing as the example, the bird impact resistance was analyzed. By comparing the mass change and energy absorption characteristics of leading-edge configurations made of several different materials, such as composite skin honeycomb sandwich structure with and without energy absorption board, it was found that the pure metal leading edge had advantages in bird impact resistance. The test data was in line with the result of simulation calculation. The peak strain of the test curve was 0.0108 and that of the simulation result was 0.0103, the difference was only 5%. The simulation results are effective and meet the expected requirements. |
