摘　　要：针对飞行器复杂自然环境组成,介绍了阵风紊流模型对飞行器仿真试验置信度的影响;基于随机波浪理论,建立了阵风紊流数学模型,研究了阵风紊流模型计算机建模方法;基于Davenport谱建立了阵风紊流模型,并引入到某型号飞行器数学仿真试验中,得出了阵风紊流对于飞行器飞行状态和命中精度的影响情况。研究表明:在仿真试验中引入阵风紊流模型是可行的;同时,阵风紊流会引起飞行器攻角、侧滑角的高频变化,降低飞行器飞行品质和飞行器命中精度。Aiming at the composition of aircraft complex natural environment,the influence of wind turbulence model on the confidence degree of aircraft simulation test is introduced.Based on the random wave theory,the mathematical model of wind turbulence is established,and the computer modeling method of wind turbulence model is studied.Based on Davenport spectrum,a wind turbulence model is established,and one numerical simulation test of a certain type of aircraft is developed,which obtained the effect of wind turbulence on aircraft flight state and hit accuracy.The results show that it is feasible to introduce the wind turbulence model in the aircraft simulation test.At the same time,the wind turbulence can cause the high frequency change of the angle of attack and sideswipe of the aircraft,which can reduce the flight quality and hit accuracy of the aircraft.
