摘　　要：为提高机场运行效率,缩短尾流间隔,探究加速飞机尾流快速耗散的方法。使用ANSYS模拟仿真地面喷气气流环境下A330飞机尾涡的耗散情况。选取A320作为遭遇尾流的飞机,使用条带状法进行喷气条件下的空气动力学响应分析。并将加速尾涡耗散后的安全间隔与ICAO RECAT标准相比较,探究尾流间隔缩减效率。结果表明,喷气气流能够促进涡量的扩散,抑制尾涡的下沉速度和二次弹起,加速飞机尾流耗散,促进尾涡流场垂向速度的减小。降低飞机尾流遭遇的危险,缩减前后机的最小尾流间隔。但喷气气流会促进尾流涡核间距的增大,不利于平行近距跑道配对进近的实施。In order to improve the efficiency of airport operation and shorten the wake vortex separation,methods to accelerate the rapid dissipation of aircraft wake vortices are explored.ANSYS simulation is used to simulate the dissipation of A330 aircraft wake vortex under jet airflow environment.The A320 is selected as the aircraft that encounters the wake vortex,and the aerodynam-ic response under jet conditions is analyzed using the strip method.The safe separation after accelerated wake vortex dissipation is also compared with the ICAO RECAT standard to explore the efficiency of wake separation reduction.The results show that the jet airflow can promote the diffusion of vortex volume,inhibit the sinking speed and secondary pop-up of the wake vortex,accelerate the aircraft wake dissipation,and promote the reduction of the vertical velocity of the wake vortex field.It reduces the danger of air-craft wake encounter and shrinks the minimum wake separation between the front and rear aircraft.However,the jet airflow pro-motes the increase of the tail vortex core spacing,which is unfavorable to the implementation of the paired approach(PA)proce-dures for Closely Spaced Parallel Runways(CSPR).
