摘　　要：鸟撞对航空器的破坏往往是灾难性的。作为低空域航空器的直升机发生鸟撞的概率很高,特别是其高速旋转的旋翼系统部件如主桨叶变距拉杆,发生撞击时与鸟的相对速度大,极可能产生导致功能失效的严重危害。按照民用航空器适航条款的规定,采用鸟撞仿真分析和试验验证相结合的方法,准确评估主桨变距拉杆的抗鸟撞性能。There were a lot of bird strike chances for the helicopter because of frequently flight in the lower airspace,and it was usually a disaster when unexpected bird strike happened especially on the high speed rotation parts for example Main Rotor Pitch Control Rod due to lose capacity after the high speed strike between the part and bird,it was necessary to evaluate the damage of bird strike according to the JAR/FAR/CCAR29. 631.
