大气边界层环境影响效应的仿真试验

Simulation Experiment of Environmental Effects in the Atmospheric Boundary Layer

研究利用动力模拟与气候统计相结合的方法建立典型大气边界层环境基本要素(风速、温度、气压和密度)场仿真模型,以低空飞行器为仿真算例,在实现大气边界层环境仿真模型与飞行动力学仿真模型耦合的基础上,开展大气边界层环境影响效应的仿真试验,分析大气边界层环境对低空飞行器飞行轨迹和姿态特性的影响。通过探索大气边界层环境模型建立的可行性及其对低空飞行器影响的基本规律,为进一步开展大气环境对武器系统影响评估研究提供思路。

The typical simulation models of the essential meteorological element （wind, temperature, pressure and density） fields in the atmospheric boundary layer are established by combining the statistical and dynamical method. Based on the simulation models of the atmospheric boundary layer environment coupling with flight dynamic simulation model, the simulation experiment of environmental effects in the atmospheric boundary layer was realized by taking the aircraft in low altitude as an example. The effects of atmospheric boundary layer environment on the flight track and flight attitude characters of the aircraft were analyzed. An idea was put forward to evaluate the atmospheric environmental effects on weapon system from exploring the feasibility of the models of atmospheric boundary layer environment and the basic regulations of environmental effects on the aircraft in low altitude.
