In view of the booming of flight flow of urban logistics UAVs and low airspace utilization due to isolation mode of operation, safe and efficient cross-operation needs to be implemented. The crossing separation model was constructed by studying the crossing operation collision risk at the same altitude, and the core parameters such as lateral error, vertical error and longitudinal proximity rate were determined. By introducing the Event model method and constructing separation model, the failure probability of airborne CDR system was further considered. By using event tree analysis method, a comprehensive model of urban logistics UAV crossing separation was proposed and constructed. Results show that the required crossing separation is 158 m for the target safety of level 1.5×10-8 and 155 m for the target safety of level 1×10-6 when the route angle is 60 degrees. With the increase of crossing angle, the required separation generally shows an upward trend. When it approaches 180°, that is, opposite direction operation, the required separation increases sharply, which is consistent with the actual cognition.

为解决城市物流无人机飞行流量加大、隔离航线模式空域利用率低的矛盾,需要实施安全有效的交叉运行。通过研究交叉运行碰撞风险,确定侧向误差、垂直误差、纵向临近率等核心参数,构建同高度交叉运行间隔模型。在此基础上,进一步考虑机载冲突探测与解脱(CDR)系统失效问题,并运用事件树分析方法,提出并构建城市物流无人机交叉间隔综合模型。结果表明:在航线夹角为60°情况下,对标安全目标水平1.5×10-8,所需交叉间隔为158 m;对标安全目标水平1×10-6,所需交叉间隔155 m。随着交叉角度增大,运行间隔总体呈现上升趋势,当接近180°时,即对头运行时,所需间隔急剧上升,与实际认知一致。

为解决城市物流无人机飞行流量加大、隔离航线模式空域利用率低的矛盾,需要实施安全有效的交叉运行。通过研究交叉运行碰撞风险,确定侧向误差、垂直误差、纵向临近率等核心参数,构建同高度交叉运行间隔模型。在此基础上,进一步考虑机载冲突探测与解脱(CDR)系统失效问题,并运用事件树分析方法,提出并构建城市物流无人机交叉间隔综合模型。结果表明:在航线夹角为60°情况下,对标安全目标水平1.5×10-8,所需交叉间隔为158 m;对标安全目标水平1×10-6,所需交叉间隔155 m。随着交叉角度增大,运行间隔总体呈现上升趋势,当接近180°时,即对头运行时,所需间隔急剧上升,与实际认知一致。

In view of the booming of flight flow of urban logistics UAVs and low airspace utilization due to isolation mode of operation, safe and efficient cross-operation needs to be implemented. The crossing separation model was constructed by studying the crossing operation collision risk at the same altitude, and the core parameters such as lateral error, vertical error and longitudinal proximity rate were determined. By introducing the Event model method and constructing separation model, the failure probability of airborne CDR system was further considered. By using event tree analysis method, a comprehensive model of urban logistics UAV crossing separation was proposed and constructed. Results show that the required crossing separation is 158 m for the target safety of level 1.5×10-8 and 155 m for the target safety of level 1×10-6 when the route angle is 60 degrees. With the increase of crossing angle, the required separation generally shows an upward trend. When it approaches 180°, that is, opposite direction operation, the required separation increases sharply, which is consistent with the actual cognition.
