| 摘 要： | 基于旋翼综合气弹分析程序,求解出直升机旋翼桨叶在飞行过程中的稳态响应。以此作为鸟体撞击桨叶的初始状态,采用非线性流-固耦合算法,建立了直升机旋翼桨叶鸟撞动力学方程,利用直接数值积分方法求解桨叶的动态响应。并讨论了鸟体速度、质量、撞击位置、桨叶根部约束和离心力等参数对桨叶动态响应的影响,从而为直升机桨叶抗鸟撞设计提供一些理论依据。

| Abstract: | The steady-state response of the helicopter rotor in flight is solved by using its comprehensive aeroelastic analysis program. The result is then used for the initial state of bird impact on the blade. The bird impact dynamic equation of helicopter rotor blade is established by adopting non-linear fluid-solid coupling algorithm. Finally the dynamic response of blades is solved by using direct numerical integration method.To provide some theoretical basis for the anti-bird impact on helicopter blade design, the system parameters such as bird speed、bird quality、impact position、blade root constraint and rotation speed were discussed in the paper. |
