The invention discloses a ground intervention device for accelerating aircraft wake flow dissipation, which comprises plate line systems which are arranged in parallel, obvious secondary vortexes aregenerated under the action of plate lines according to comparison of vorticity vector diagrams under the action of a plate-line-free system and the plate line systems, and due to the fact that tangential airflow of the wake vortexes is blocked and segmented, turbulent kinetic energy of the trailing vortex is disturbed and restrained, meanwhile, downwash airflow of the trailing vortex is blocked between a plate line and the ground, the speed and direction of the airflow are changed, a main vortex of the trailing vortex deforms, a secondary vortex is induced to be separated out, an interferencedragging effect is generated on the main vortex, and strength attenuation and dissipation of the vortex are intensified, according to the plate line system, the trailing vortex dissipation speed can be increased, the influence of the wake flow on the rear aircraft is reduced, so that the wake flow interval is reduced, the airport capacity and the airspace use efficiency are improved, and the increasing air transportation requirements are met.

    本发明公开了一种加快航空器尾流耗散的地面干预装置,包括平行排列的板线系统,通过无板线系统与该板线系统作用下的涡量矢量图对比可知,在板线的作用下,产生了明显的二次涡流,由于尾涡的切向气流受到阻挡、分割,干扰和抑制了尾涡的湍流动能,同时尾涡的下洗气流被阻滞在板线和地面之间,气流速度的大小和方向发生改变,尾涡主涡变形,诱导分离出二次涡流,对主涡产生干涉拖拽作用,加剧涡的强度衰减和耗散,该板线系统能够加快尾涡耗散速度,减小尾流对后机的影响,从而缩减尾流间隔,提高机场容量及空域使用效率,满足日益增长的航空运输需求。
