分析了航空器换道的运动学过程,根据航空器之间的冲突距离建立了航空器的平行航路换道模型,并对航空器匀速和匀加速换道进行对比,模型表明换道航空器之间的冲突距离与两航空器之间的相对纵向加速度、相对纵向速度以及换道时间等因素有关。最后,经仿真计算得到航空器匀速与匀加速换道时分别与相邻航空器不发生冲突的理论安全距离区域。 The kinematic process of aircraft lane change is analyzed and the parallel lane change model of the aircraft is established according to the collision distance between the aircraft. The uniform and accelerated lane change of the aircraft is compared. The model shows that the conflict distance between the lane change aircraft and Relative longitudinal acceleration between two aircraft, relative longitudinal speed and lane change time and other factors. Finally, the theoretically safe distance between the aircraft and the adjacent aircraft is obtained through simulation calculation.
