摘要

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

Abstract

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 flig

ht 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 remaining control surfaces neutral; To achieve the objective of reducing control energy by minimizing the absolute deviation angle of the control surface

the mid lift aileron configuration is adopted to trim

while the remaining control surfaces are neutral; To achieve the objective of reducing radar reflection by minimizing the deviation angle difference between control surfaces

three sets of lift ailerons are simultaneously tilted up by

°. Based on aerodynamic data

the rationality of the above results was analyzed. Combining three single objective problems pairwise and using a non-dominated sorting genetic algorithm to solve

Pareto non inferior solutions were obtained. It was found that the three balancing objectives were conflicting pairwise

and improving the performance of one objective would reduce the performance of the other objectives

but the proportion of performance reduction was different. Taking into account three optimization objectives

The ideal point minimum distance method is adopted to select the optimal configuration from Pareto non inferior solutions. The final trim configuration is
