为了提高我国近距平行跑道的运行效率,对配对进近方式的安全区域进行研究。根据配对过程中快机和慢机的相对运动关系和速度特征,将配对进近分为快机不可超越慢机和快机超越慢机两种方式。将慢机作为参考量,分析快机的相对运动状态,定性地给出两种配对方式的安全区域范围。在此基础上,考虑慢机错误地闯入快机航向道,建立防撞安全边界计算模型;考虑配对前机在最大不利侧风影响下的尾流对后机的影响,建立尾流安全边界模型。利用虹桥机场的相关数据,采用C类航空器B737-800,D类航空器B747-400作为配对进近的两架飞机,对模型进行验证。结果表明:该方法可以实现实时定量地计算两种配对方式下的安全区域范围。
In order to improve the running efficiency of near-parallel runways in our country, the safe area of pairing approach is studied. According to the relative motion and speed characteristics of the fast and slow machines in the pairing process, the paired approaches are divided into two types: the fast machine can not exceed the slow machine and the fast machine exceed the slow machine. The slow machine as a reference quantity, the relative movement of the fast machine state analysis, qualitatively give two kinds of matching methods of the safe area range. On the basis of this, we consider that the slow machine intrudes into the heading course quickly and establishes the calculation model of the collision safety margin. Considering the impact of the wakes on the rear machine under the influence of the maximum unfavorable crosswind, the wake safety margin model. Based on the data of Hongqiao Airport, the model was verified by using Class B aircraft B737-800 and Class D aircraft B747-400 as the two aircraft matching the approach. The results show that this method can realize the real-time and quantitative calculation of the safety area under two kinds of pairing methods.
