摘要
研究了直升机旋翼下洗流场的相似性。从弹箭运动控制方程出发，将下洗流场作为纵风效应，详细推导和分析了弹道相似所必须满足的相似准则，以及满足这些准则所必须满足的条件，从而为建立直升机空中发射环境地面模拟实验装置奠定了理论基础。
The similarity of rotor-wing down-wash flow field is studied. Based on the controlling equations of rocket movement, the criteria of initial trajectory similarity are deduced and analyzed in detail with the down-wash flow considered as a wind effect. Conditions required by the above criteria of similarity are proposed. These results provide a theoretical basis in establishing experimental device for the ground simulation of helicopter air-launching environment.
