Impact modeling of composite aircraft structures

这是一个在CRIAQ行业主导项目计划下进行的研究和开发项目。其目的是发展复合材料飞机结构高速冲击响应的设计方法和预测数值模拟方法。重点是为复合材料和金属飞机开发增强的耐撞性仿真工具和实用的故障建模和验证。这是加拿大航空业迫切需要的，因为纤维增强复合材料越来越多地用于飞机的主要结构，如机身部分、机翼前缘、机舱、螺旋桨和航空发动机导管和风扇叶片。这些部件容易受到鸟撞和异物的高速撞击，或者受到不同表面上可幸存的坠毁着陆的冲击，这可能会对飞机安全构成严重威胁。

This is a research and development project run under the CRIAQ industry driven project scheme. Its aim is to develop design methodologies and predictive numerical simulation methods for the high velocity impact response of composite aircraft structures. The focus is on developping enhanced crashworthiness simulation tools and practical failure modeling and validation for composites and metallic aircraft . It is urgently required by the Canadian aircraft industry since fibre reinforced composite materials are increasingly being used in primary aircraft structures such as fuselage section, wing leading edges, nacelles, propellers and aeroengine ducts and fan blades. These parts are susceptible to high velocity impacts either from bird strike and foreign objects or from shock of survivable crash landings on different surfaces that can pose a serious risk to aircraft safety.
