引入时间变量和时间间隔变量,分析了飞机之间任意时刻的标称间隔和碰撞风险,建立了基于时间间隔分布、飞机流率、机型比例与转弯角的碰撞风险模型,计算了转弯航路的碰撞风险,分析了不同参数对碰撞风险的影响。分析结果表明:碰撞风险是随着航段起始点到转弯点的距离与飞机流率的增大而逐渐增大,随着飞机到达转弯点的最小时间间隔的增大而逐渐减小。可见,此模型简单可靠。
The variable of time and the variable of time interval are introduced to analyze the nominal interval and the risk of collision at any time between aircraft. The collision risk model based on time interval distribution, aircraft flow rate, model ratio and turning angle is established. Collision risk, the impact of different parameters on the risk of collision is analyzed. The analysis results show that the collision risk increases with the distance from the starting point of the segment to the turning point and the flow rate of the airplane, and decreases with the increase of the minimum time interval at which the airplane reaches the turning point. Visible, this model is simple and reliable.
