摘要: 为提高机场地面运行安全,预防航空器产生滑行冲突,研究了基于航空器特性的机场地面交叉口冲突概率并建立了相应的估计模型。该模型将发动机喷流影响有效距离因素引入到交叉口冲突范围中,描述了航空器滑行冲突的过程。结合实际运行数据对模型进行了验证和数据分析,探讨了速度区间对模型的影响。模型针对三种运动状态航空器滑行冲突概率的变化进行分析,当速度变化区间为0.5 m/s时,冲突概率分析较为理想,能在贴近客观实际的前提下较好地提高冲突概率计算的准确性。仿真结果表明:减速等待避让策略能够有效减小航空器冲突概率,预防事故的发生;该模型能实时计算航空器的冲突概率,可用于航空器地面冲突预警。

Abstract: Based on aircraft characteristics, the assessment model of conflict probability at airport surface intersection was studied to ensure the safety of airport ground safety. The engine jet effect distance was introduced to expand the scope of intersection conflict, describing the process of aircraft conflict. The model with the actual operation data was verified, and the speed interval's impact on the model was analyzed and discussed. In the view of three motion states of aircraft, this model analyzed the variations in conflict probability. When speed variation range is 0.5m/s, probability analysis of the conflict is more ideal, and can improve the accuracy of calculating the probability of conflict under the premise of objective reality. The results show that: decelerating and holding avoidance measures can reduce the aircraft conflict probability effectively, thus defending the occurrence of accidents. This method can accurately calculate the conflict probability of aircraft, suitable for aircraft ground conflict alert.

Key words: air traffic management, airport surface intersection, speed range, conflict probability
