The focuses of this paper are on flight environment simulation and high span - chord ratio uav model 本文的工作就是围绕飞行环境模拟和无人机动力学仿真展开。
For the first time , flight simulation related to high span - chord ratio uav based on variable windfield is executed , the facticity of windfield and its influence to flight performance curve are analyzed . 5 首次针对大展弦比无人机,进行变化风场中飞行仿真,讨论各风场模型的真实性及其对飞行性能曲线的影响; 5
The results show that the drag of grid fins is little affected by width to chord ratio , the normal force of grid fins was large , and that the smaller was the ratio , the better was the characteristics of the grid fins ' s normal force in tested sizes of width to chord ratios 结果显示,在所选择的格宽翼弦比范围内,格宽翼弦比对阻力的影响不大,对法向力有明显的影响,格宽翼弦比越小法向力特性越好。
