【摘要】 综合自然环境包括地形、大气/气象、海洋、空间四大领域,变化风场作为大气环境中的重要组成部分,其对飞行器使用性能的影响不容忽视。针对变化风场对飞行影响的两种主要表现形式,分别以风切变和大气紊流建立工程化的风场模型,并以某型导弹为仿真算例,分析了所建立的变化风场模型对导弹弹道、姿态特性的影响,验证了所建立变化风场模型的有效性和工程实用性。更多还原

【Abstract】 Synthetic natural environment(SNE) includes four primary domains: terrain,ocean,air and space.As an important part of air environment,variable wind field would affect the performance of aircraft.Considering the two main representations of variable wind field,the engineering simulation method of wind shear and atmospheric turbulence were established.With a simulation example of a certain missile,the effect of variable wind field to the attitude and track characters of the missile was analyzed.The results show that the model established is valid and practicable for engineering.更多还原
