摘　　要：在建立农林飞机超低空飞行时的大气紊流模型基础上,结合频域和时域两种计算方法研究了各种不同紊流强度下的大气紊流对农林飞机超低空飞行的影响,同时采用加速度综合评分的方法对其影响进行定量评估,最后给出了大气紊流对农林飞机超低空飞行影响的规律,对工程应用有一定的参考价值。This paper establishes the atmospheric turbulence model of agricultural aircraft flying at minimum altitude. Using frequency-domain and time-domain calculation methods researches the atmospheric turbulence effects of agricultural aircraft flying at minimum altitude, at the same time using the acceleration combination evaluation method quantificationally evaluates the effects. Finding out the effect laws of the atmospheric turbulence for agricultural aircraft flying at minimum altitude. This method could be used to provide engineer applications.
