航空器跟随滑行动态冲突风险计算模型

为及时探测滑行冲突,提出航空器跟随滑行动态冲突风险计算模型。该模型抽象航空器在同一滑行道依次滑行过程,综合共享滑行段长度、初始间隔、发动机喷流、机身长度等因素,基于动态速度、位置构造冲突风险量化模型。采用Visual C++编程实现仿真程序,仿真结果表明该模型能量化匀速、变速运动中跟随冲突,冲突风险值与初始间隔成反比、与两机速度差成正比。利用监视数据验证,结果表明:模型计算结果优于传统模型,与实际运行情况相符。该模型的应用能为管制员、飞行员判断跟随滑行冲突提供理论依据,具有一定的参考价值和实用性。

Dynamic conflict risk calculation model of aircraft successively taxiing

In order to detect the conflict in time, the dynamic conflict risk calculation model of aircraft successively taxiing was proposed. This model abstracted the sequential taxiing process of aircrafts on the same taxiway, integrated the factors of shared taxiway length, initial seperation, jet flow, fuselage length, etc., and constructed a quantitative model of conflict risk based on dynamic speed and position. The simulation program was implemented by Visual C++ programming. The simulation results showed that the model could quantify the successively conflicts in uniform and variable speed motion, and the conflict risk value was inversely proportional to the initial seperation and proportional to the speed difference between the two aircrafts.Using surveillance data to verify, the results showed that the calculation results of this model were better than the traditional model and accord with the actual operation.The application of this model could provide theoretical basis for the controller and pilot to judge conflict for the successively taxiing, which had certain reference value and practicability.
