| Abstract: |
| The paper aims to research the bird strike resistance of empennage using aramid fiber.According to the two types of empennage leading edge based on foam sandwich structure and laminate structure both using aramid fiber, the finite element models of empennage structure were simulated to analyze damage and deformation and test the bird strike resistance of the two structures. The leading edge of foam sandwich structure was depressed and the fore beam was not broken. The leading edge of laminate structure and the fore beam both were broken. The test result was in good agreement with simulation.The foam sandwich structure has better effect of bird strike resistance. The laminate structure has higher maintenance cost because of overlarge deformation of leading edge skin and damage of fore beam web. |
