résumé Bird impacts on aircraft are very common and cause significant safety threats to commercial and military aircraft. According to FAA ( Federal American Aviation) regulations, aircraft should be able to land safely following specified types of bird impact on components such as radomes, windshields, engines leading edge structures and other exposed components. Thus exposed components are required to be certified for bird impact. In order to evaluate whether the aircraft is compliant to FAA requirements, several experimental tests and numerical simulations of bird impact on components need to be preformed. This paper presents an experimental and numerical investigation of bird impact on radome, a structural waterproof component that protects the radar system in aircraft and also nearby personnel from being accidentally struck by rotating antennas. In aircraft, randome structure is one of the most exposed component for bird impact. In this paper, numerical simulation of bird impact on radome component is considered, using new development of multi-material formulation and fluid structure interaction developed in LSDYNA. In order to validate the numerical results, experimental tests of bird impact on radome structural component were performed at Boeing researsh center. PDF
