摘要
从航迹规范角度研究了进近过程航空器的尾流间隔安全,并提出了一种新的尾流安全检测算法。首先对依据障碍物评估面-OAS面以及所需性能导航(RNP)所设计的航空器进场初步规划,考虑RNP的容差后进行进一步的航迹规范,接着针对可能发生的尾流间隔不足问题提出一种新的检测算法,最后用软件计算,模拟了航空器进近过程。结果表明:使用该算法检测后尾流间隔不足问题能够及时发现并且与传统碰撞模型的测评方法具有同等效力,证明了算法的正确性和初步的可实现性。
The article studies the safety of aircraft wake interval during approach from the perspective of trajectory specification, and proposes a new wake safety detection algorithm.The article first makes a preliminary plan for aircraft approach based on obstacle assessment surface-OAS surface and required performance navigation(RNP), and further trajectory specification is carried out after considering the tolerance of RNP.Then, a new detection algorithm is proposed to solve the problem of insufficient wake interval.Finally, software calculation is used to simulate the approach process of the aircraft.The results show that the problem of insufficient wake interval can be detected in time after using this algorithm, and it has the same effect as the traditional collision model evaluation method, which proves the correctness and preliminary feasibility of the algorithm.
