| 摘 要： | 自由飞行是解决空域拥挤、节省飞行时间的有效方式,为保障飞行安全,对自由飞行下的最小安全间距进行研究.针对自由飞行空域中处于不同高度且有垂直运动的航空器,构建了一种圆柱形的冲突区域,从而建立了基于冲突区域的碰撞风险模型.对于给定的安全目标水平,利用爬山法对最小安全间距进行求解.算例验证了模型的可行性.

| Abstract: | Free flight is an effective way to solve the congestion of air traffic flow and save flight time ,so minimum safety distance in free flight is studied to guarantee the security of flight under free flight .For the condition that aircraft fly on different height and have vertical movement ,to build a kind of cylindrical conflict area,and then establish the collision risk model by analyzing the relationship between the mini-mum safety distance and collision risk .Then the minimum safety distance is optimize using the hill -climbing algorithm for a given security target. |

| Keywords: | free flight collision risk conflict area minimum safety distance hill climbing method |
