Low-order equivalent matching methods for aircraft with flying wings

  • 摘要:

    特殊的操稳特性导致常规飞机的低阶等效拟配方法不完全适用于飞翼布局飞机。为保证飞翼布局飞机低阶等效拟配的准确性与成功率,对飞翼布局飞机与常规飞机在气动特性、操纵特性、控制系统设计等方面的差异进行了分析,开展了飞翼布局飞机低阶等效拟配方法研究。通过频域特性分析研究了拟配频率范围对拟配结果的影响;综合飞机的时域响应与拟配结果,对比了常用的方波、"3211"、扫频信号对飞翼布局飞机的适用性,结果表明方波信号更适用于飞翼布局飞机;通过仿真分析了指令信号强度对飞翼布局飞机拟配效果的影响;提出了横向与航向激励指令信号联合适配设计的方法,从而获得更高的横航向拟配成功率。
