【摘要】 采用筛选试验设计方法研究直升机总体参数对稳定性的影响。根据直升机线性飞行动力学方程,建立了适合直升机总体设计的稳定性分析模型,以UH-60A为样机,研究影响直升机稳定性的总体和布局参数,同时对参数进行了敏感性分析,为在直升机总体设计中考虑稳定性设计要求,选择合适的总体和布局参数提供参考。更多还原

【Abstract】 In this paper,effect of gross and configuration parameters on helicopter stability is investigated by a screening designs method.The helicopter stability analysis model which can be used in conceptual design has been set up based on the helicopter linear flying dynamics equations.Then the primary gross and configuration parameters which effect helicopter stability have been conformed using the UH-60A as a baseline helicopter.The parameters sensitivity analysis has also been done.The research provides the design rules for the proper gross and configuration parameters chose in helicopter conceptual design.更多还原
