含冗余控制面飞行器配平优化设计与性能分析OA北大核心CSTPCD
Optimal design and performance analysis of aircraft trim configuration with redundant control surfaces
含冗余控制面的飞行器配平问题是一个超静定问题,从性能需求角度构建 3 个单目标配平构型优化问题,在高度为 5 km、马赫数为 0.85 的定直平飞状态下,采用遗传算法求解.结果表明:若以最大升阻比为目标,采用内升降副翼配平,其余舵面中立;若要使配平所需控制面偏角绝对值和最小、达到降低控制能量的目的,则采用中升降副翼配平,其余舵面中立;若要实现控制面间偏角相差最小、达到减小雷达反射的目的,那么 3 组升降副翼需同时上偏 3.7882°.结合气动数据…查看全部>>
The trim problem of aircraft with redundant control surfaces is a hyperstatic problem.To determine the appropriate trim configuration,three single trim configuration optimization problems were constructed from the perspective of performance requirements.Under a fixed level flight state at an altitude of 5 km and Mach number of 0.8,genetic algorithm was used to solve the problem.Aiming for maximum lift to drag ratio,use inner lift aileron trim and keep the re…查看全部>>
