摘　　要：近距平行跑道的实施可显著地提升机场运行效率及容量,而尾流是影响进近航空器安全的关键因素。为了探究简化配对进近程序下航空器安全间隔,基于人行为误差、导航误差建立航空器进近运动模型。综合考虑侧风和大气湍流的影响,建立尾流侧向运动计算模型。对尾流遭遇严重性衡量指标进行分析,建立尾流耗散模型,结合飞机尾涡承受能力提出简化配对进近安全区域及危险区域的计算方法。最后,以国内某机场为例,计算该机场实施简化配对进近程序的有效起始安全区及危险区。该研究对优化配对飞机单元间尾流间隔,提高机场运行安全及效率具有一定的参考价值。The implementation of closely spaced parallel runways can significantly improve the airport’s operational efficiency and capacity,and wake is a key factor affecting the safety of approaching aircraft. In order to explore the aircraft’s safe interval under the simplified paired approach procedure,an aircraft approach motion model is established based on human behavior errors and navigation errors. Considering the influence of crosswind and atmospheric turbulence,a model for calculating lateral motion of wake is established. Analysis of the severity index of wake encounter is conducted,a wake dissipation model is established,and a simplified calculation method for the safe and dangerous areas of the approach paired considering the ability of the aircraft to withstand the wake vortex is proposed. Finally,taking an airport in China as an example,this paper calculates the effective starting safe area and dangerous area for the airport to implement simplified paired approach procedures. This study optimizes the wake separation between paired aircraft units. It has reference value to improve airport operation safety and efficiency.
