摘　　要：为了便于分析和改进直升机进口惯性粒子分离器性能,在自行开发出的分离器参数化造型软件的基础上,选取了控制分离器主流道出口截面积和清除流道出口截面积等7个重要参数,以现有分离器原型作为参照样本,对不同几何参数下的分离器性能进行细致的分析和比较。对比计算模型的颗粒分离效率和总压损失,提出了两个改进模型。与原模型相比,改进模型对于大尺度颗粒的分离效率有很大改善,即从原来的不到20%增加到了95%,而总压损失仅增加约1%。To facilitate an analysis and improvement of the performance of an inertia particle separator at the inlet of a helicopter,on the basis of a self-developed parameterization modeling software for separators,chosen were seven important parameters for controlling the sectional area at the outlet of the main flow passage of a separator and eliminate the sectional area of the passage outlet etc.With the prototype of the currently available separators serving as the reference specimen,a meticulous numerical analysis and comparison were conducted of the performance of the separator under various geometric parameters.On the basis of a comparison of the particle separation efficiencies and total pressure losses obtained by using the calculation model,presented were two improved models.Compared with the prototype model,the improved models can lead to a very big enhancement of the separation efficiency for large-sized particles,i.e.increasing from the original 20% to over 95% while the total pressure loss increases by only about 1%.The foregoing can provide certain basis for optimization of the profile of an inertia particle separator.
