大型飞机遭遇微下冲流时,最安全的方法就是规避。在规避过程中,考虑了飞行员的乘坐舒适性(侧向过载限制)和飞机最低安全高度限制两个约束条件。首先,建立了受约条件下的规避数学模型;然后,结合模型分析了飞机在不同高度、速度及告警距离等条件下,横航向规避飞行参数和相应的规避轨迹;最后,通过分析和仿真得到了飞机遭遇微下冲流时的安全规避半径、规避角速度和规避时间,同时给出了不同告警距离下飞机规避时的最小安全高度曲线。
The most secure way to deal with a large aircraft is to avoid it. During the avoidance process, the two constraints of the pilot’s ride comfort (lateral overload limit) and the aircraft’s minimum safety height limit are taken into account. First, the avoidance math model under the condition of acceptance is established. Then, with the model, the flight parameters and the corresponding avoidance trajectories are avoided in the cross-heading under different altitudes, velocities and warning distances. Finally, through the analysis and simulation, The safety avoidance radius, avoidance angular velocity and avoidance time when the aircraft encounters micro-inflows are given. At the same time, the minimum safety height curve of the aircraft during avoidance of different warning distances is given.
