| Abstract: |
| The work aims to study the performance of civil aircraft fuel tank cover on withstanding the engine debris according to the requirement of airworthiness standards CCAR25.963-e-1. The airworthiness certification process of fuel tank cover withstanding engine debris was developed according to the airworthiness certification requirements. The impact area and angles of fuel tank cover for airworthiness certification were defined. The finite element model of engine debris was established. The simulation analysis and laboratory test were carried out to the capability of the fuel tank cover on withstanding engine debris. After analyzed comparatively, the simulation results and test results were approximately consistent and the simulation analysis could basically predict the test results. The simulation method can be used to design the fuel tank cover withstanding debris. The airworthiness certification process of fuel tank cover withstanding debris can be referred for similar aircraft airworthiness certification. |
