摘要
飞机尾流观测试验是研究飞机尾流演化耗散行为的基础。受到不同大气环境的影响,针对巡航、进近等阶段的飞机尾流观测具备一定的挑战性。本文综述了以风洞和拖曳水池为主的飞机尾流实验室观测,以及以激光雷达及微波雷达为主的飞机尾流现场观测的研究成果和研究进展。尾流的风洞观测试验能较好地实现对近区内飞机尾流卷起、发展、脱落,特别是对近区内尾流合并过程(包括飞机翼尖涡、襟翼涡、水平尾翼涡、发动机喷流间的合并)的观测;尾流的拖曳水池观测试验能较好地实现对飞机尾流在扩展近区、及中区内演化过程的观测。尾流的现场观测试验能有效地获取飞机尾流在真实大气背景场中的演化耗散过程,从而为研究不同大气背景条件对飞机尾流的影响,并进而建立飞机尾流动态间隔标准提供重要参考。
Observational experiment of aircraft wake vortex is the basis of studying the evolution behavior of aircraft wake vortex.Disturbed by the effects of atmospheric environment,the exact observation of aircraft wake vortex in cruising and approaching is challenging.In this paper,the laboratory wake observation method including the wind tunnel and towing tank experiment,and the in-site observation method using laser radar and microwave radar equipment has been discussed.The wind tunnel experiment is able to capture the roll-up,development,fall out of the aircraft wake vortex as well as vortices merging(including merging among the wing tip vortex,flap vortex,horizontal tailplane vortex,jet-flow,etc.), while the towing tank experiment can well capture the evolution behavior of aircraft wake vortex in the extended near field and mid field.In addition,the in-situ observational experiment can well capture the process of evolutionary dissipation of aircraft wake vortices in the atmospheric environment,so it can be served as an important reference for studying the effect of different atmospheric environment on the evolution process of aircraft wake vortices,and further for establishing the dynamic separation standard of aircraft wake vortex.
