基于正交试验的混合翼无人机旋翼位置优化
Rotor position optimization of a hybrid configuration UAV based on orthogonal experiment
摘要
Abstract
Rotor is an important part of hybrid configuration unmanned aerial vehicle(UAV).It is of great signifi-cance to investigate the influence criteria of rotor positions on aerodynamic characteristics of UAV.The aerodyna-mic characteristics of a typical hybrid configuration UAV is analyzed by numerical method.Taking the lift-to-drag ratio and longitudinal static stability as the optimization objectives,a three-factor four-level orthogonal experimen-tal of the chord-wise,span-wise and vertical positions of the rotor is designed.The effects of three factors of rotor position are analyzed by means of intuitive analysis and computational analysis.The results show that the maximum lift-to-drag ratio of the optimized design parameter combination obtained by the orthogonal test design result is about 2 times larger than that of the initial design parameter combination,and the slope of the pitch moment coeffi-cient curve is increased by about 15%.For present configuration,the effect factors on the lift-to-drag ratio and the slope of the pitch moment coefficient curve are in a descending order as follows:chord-wise,span-wise and verti-cal positions.关键词
