摘　　要：采用较真实的三维微下击暴流工程化模型和非线性动态逆方法,对飞机在起飞过程中的纵向/横侧改出低空风切变的控制律进行了设计和仿真。计算了不同的机载前视探测距离对改出机动效果的影响。根据仿真得出的各飞行参数对纵向、横侧控制仿真结果进行对比分析,结果表明,横侧机动能明显维持飞机在改出风切变机动中的飞行性能和生存能力,较长的前视探测距离更有利于飞机改出。An axisymmetric, three-dimensional engineering model of microburst was used in the simulation of aircraft take-off with windshear encounter. The employed control law of longitudinal and lateral maneuver was built using nonlinear inverse dynamics （NID） method. The simulation flight parameters and microburst parameters of longitudinal and lateral maneuver were analyzed. The analysis results show that the aircraft flight performance and survival ability are more effective in lateral maneuver.
