摘要
无人直升机操纵响应特性研究的关键是有准确的旋翼诱导速度模型。本文介绍了确定旋翼非定常入流分布特性的最新方法—旋翼动态入流模型。并以欧拉方程为基础,结合动态入流模型,计算了某型无人直升机的操纵响应特性。
The key to investigate control response characteristics of unmanned helicopter is to determine the correct induced velocity model. In this paper, the rotor dynamic inflow model, the latest method to determine rotor non-steady inflow characteristics , is introduced. On the basis of Euler equation, the control response characteristics of a kind of unmanned helicopter is calculated incorporating dynamic inflow model.
