主要研究并建立直升机飞行性能仿真模型,在直升机动力学和运动学微分方程的基础上重点解算作用在直升机各部件上的气动力和力矩模型,建立旋翼和尾桨的气动仿真模型,对旋翼挥舞运动进行了分析研究,还考虑了平尾、垂尾、机身和重力的仿真模型.最后通过对各飞行性能指标及其验证原理方法的分析研究,验证了静态性能指标,应用标量指标法验证动态性能指标.%This thesis mainly research and found the simulation model of flight performance of helicopters. On the basis of helicopter's dynamics and kinematics differential equation, mainly calculate the aerodynamic and moment models which act on the parts of helicopter. Found aerodynamic and moment model of rotor and tail rotor,analyze and research the wave of rotor,finally take the models of horizontal tail,vertical tail,airframe and gravity into account. At last, through analyze and research the flight performance and the validated methods, validate the static indicators of flight performance, and use scalar quantity index to validate the dynamic indicators of flight performance.
