基于导航函数的直升机任务科目建模试飞技术

Flight test technologies of helicopter MTEs modeling based on navigation function

任务科目是ADS-33E规范要求的直升机飞行品质重要考核项目之一。基于导航函数的方法,通过直升机非线性飞行动力学模型实现任务科目的数值仿真,获得目标直升机任务科目所需的操纵量及操纵规律。通过飞行试验结果的验证及分析表明,数值计算结果及模型真实有效,对直升机任务科目的飞行试验具有指导作用。

The MTEs are an important helicopter flight quality assessment project required by the ADS-33 E specification. Based on the navigation function,this paper obtained the required control amplitude and control rule of the target MTE through the nonlinear flight dynamics model of helicopter to realize the numerical simulation of the MTEs. Compared with the results of flight test,the numerical results and the model are true and effective,which can guide the flight test of the helicopter MTEs.
