直升机飞行品质评估数学模型研究

针对飞行品质评估需要，结合建模工作中的经验，讨论了模型复杂度和真实度之间的关系，分析了不同阶次的入流模型和非定常气动模型对结果的影响，考虑了旋翼尾迹对机身的气动干扰作用，并对涡轮轴发动机和飞行控制系统模型在飞行力学模型中的重要作用做了阐述。还地逆仿真方法在飞行品质研究中的应用提出了一些见解。

Investigation of helicopter mathematical modelappropriate for flying quality evaluation

A helicopter mathematical model was developed for the aim of flying quality investigation. The relation of complexity and fidelity of the mathematical model was discussed. Induced inflow model is the most important role in the total mathematical mode. Unsteady airloads model is not so important as inflow in the first step of flying quality analysis, but it is substantial part in the flight simulation program. The aerodynamic interfere model is not a neglectable factor for the flight control system design. The flight control system and engine models are very important in this topic. We also give our opinions of the inverse simulation in the applications of flying quality in this article.
