直升机操纵稳定性优化设计

摘要

To improve the helicopter stability and control, the analysis model of helicopter stability and control is built based on the principle of helicopter preliminary design. The optimization design method is used to select the appropriate basic parameters, thus improving the helicopter stability and control.The approach to the optimization design method is feasible and efficient by taking the helicopter UH-60A as an example. Compared with the classic numerical optimization algorithm, the intelligent optimization algorithm and the hybrid optimization algorithm, the last one is more suitable for solving the optimization design model of helicopter stability and control.%为了提高直升机操纵稳定性,建立了适合直升机总体设计的操纵稳定性分析模型,通过优化设计选择合适的总体参数和布局参数,以获得优良的直升机操纵稳定性.以UH-60A直升机为算例,结果表明该直升机操纵稳定性优化设计方法是可行和有效的;同时对比经典数值优化算法、智能优化算法和混合优化算法,发现混合优化算法更适合直升机操纵稳定性优化设计模型的求解.
