本文研究了直升机在大气紊流中的响应。文中假设大气紊流是一个在时间上平稳、在空间上均匀的随机场,紊流速度在桨盘上是线性分布,并以Von Karman模型来描述其频谱。诱导速度采用涡流理论导出的非均匀分布模型。 本文以其典型直升机为算例,计算了直升机对大气紊流的响应,并分析各紊流分量对直升机响应值的影响。 This paper studies the helicopter’s response to atmospheric turbulence. It is assumed that the atmospheric turbulence is a stochastic, spatially uniform field in time. The turbulent velocity is linearly distributed on the paddle, and its spectrum is described by the Von Karman model. Induction velocity is derived using the eddy current theory of non-uniform distribution model. In this paper, the typical helicopter is taken as an example, the helicopter response to atmospheric turbulence is calculated, and the influence of each turbulence component on helicopter response is analyzed.
