摘要
目前,研究大气扰动对飞艇的影响,广泛使用简化大气扰动模型,又称工程化模型。以大气紊流为特例,分析了其对飞艇性能的影响。首先,给出了大气紊流的基本情况,包括其频谱特性、扰动特性、尺度和强度,给出了其仿真模型。并给出风场干扰飞艇的模型情况,分别在线性化和非线性化模型上加入大气紊流,进行仿真分析。通过仿真结果,研究了其对飞艇运动性能的影响。
Nowadays, the simplified atmosphere disturbance model, which is also called engineering model, is widely used when researching the influence of atmospheric disturbance on the airship. The airship performance influenced by the atmospheric disturbance is mainly analyzed. Firstly, the basic features of the atmospheric dis- turbance are given, including spectrum properties, disturbance characteristic, scale and strength. Then the simulation model is set up, the wind field is added and the simulation analysis is accomplished on the basis of the linear and nonlinear model. According to the simulation result, the turbulence effect on the airship motion performance is studied.
