摘　　要：面对多类型航空器混合运行空域中的尾流安全与间隔问题,综合考虑飞机操纵特性及滚转阻尼等因素,建立了飞机尾涡安全评估模型;对典型机型组合下的多个尾涡遭遇受扰参数极限值进行统计后得到可接受安全指标水平;对混合空域中大型运输机和客机的尾涡形成及消散过程进行分析,并计算混合机型组合下的尾涡遭遇响应特性及所需安全间隔。结果表明:某大型运输机形成的尾涡强度介于B747及B767飞机之间,但消散速率明显强于民机。采用多个扰动参数可有效评估大型运输机和客机的尾涡遭遇安全性。本文建立的模型可满足未来多用户的混合运行需要,提高空域资源的利用率。Aiming at the wake vortex safety and separation in the mixed airspace of multiple types of aircraft,an aircraft wake safety assessment model was established considering the factors such as aircraft handling characteristics and roll damping.The acceptable safety standards were obtained by statistical analysis of the disturbance parameter limits of multiple vortex encounters under typical aircraft combinations.The formation and dissipation process of trailing vortices of large transport aircraft and civil aircraft in mixed airspace were analyzed,and the response characteristics of trailing vortices encounter and the required safety separation were calculated.The research results show that the initial wake circulation of a transport aircraft is between the B747 and B767,but the dissipation rate is relatively large.It can be seen that multiple disturbance parameters can be used to effectively evaluate the safety of civil-transport aircraft wake encounter.The model established in this paper can meet the mixed operation needs of multiple users in the future and improve the utilization rate of airspace resources.
