Gust Simul ating Technique in Environmental Wind Tunnel;
环境风洞中的阵风模拟技术
Under the circumstance of no digital-analogic simulation system in simulative laboratory this paper presents a dynamic physical simulative method of flight control system for a remote pilotless aircraft on an anologue computer,in which the nonlinear equation of six degrees-of-freedom is adopted and the disturbance of gust is processed.
在不具备数模混合仿真实验的条件下,本文提出了在模拟计算机上,无人驾驶飞机六自由度非线性全量方程的飞行控制系统动态物理模拟仿真和对阵风扰动处理的方法。
The technologies are studied carefully for such environmental parameters as temperature, solar radiation and gust spectrum.
本文主要针对温度环境、太阳辐射及阵风环境模拟技术进行了详细研究。
