Abstract

At airports, runway operation is the limiting factor for the overall throughput; specifically the fixed and overly conservative ICAO wake turbulence separation minima. The wake turbulence hazardous flows can dissipate quicker because of decay due to air turbulence or be transported out of the way on oncoming traffic by cross-wind, yet wake turbulence separation minima do not take into account wind conditions. Indeed, for safety reasons, most airports assume a worst-case scenario and use conservative separations. However, with the aid of accurate EDR (Eddy Dissipation Rate) retrieval by Ultra-Fast High-Range Resolution X-band Electronic-Scanning radar sensors, more efficient intervals can be set, particularly when atmosphere is unstable and turbulent, accelerating Wake-Vortex decay. Depending on traffic volume, these adjustments can generate capacity gains, which have major commercial benefits. This paper presents Electronic scanning radar trials at Toulouse-Blagnac Airport for UFO (Ultra-Fast wind sensOrs for wake-vortex hazards mitigation) project, funded by European FP7 program, on Radar EDR retrieval & Calibration.

用超高速高距离分辨率电子扫描x波段机场雷达反演涡散率(EDR):欧洲FP7 UFO图卢兹机场试验结果

在机场，跑道运行是总吞吐量的限制因素;特别是固定的和过于保守的ICAO尾流分离最小值。尾流湍流危险流可能由于空气湍流的衰减而消散得更快，也可能被侧风吹离迎面而来的交通，但尾流湍流分离最小值没有考虑风力条件。事实上，出于安全考虑，大多数机场都会假设最坏的情况，并使用保守的间隔。然而，借助超高速高分辨率x波段电子扫描雷达传感器精确的EDR(涡流耗散率)检索，可以设置更有效的间隔，特别是在大气不稳定和湍流，加速尾流衰减的情况下。根据交通量的不同，这些调整可以产生容量增益，这具有重大的商业效益。本文介绍了由欧洲FP7计划资助的图卢兹-布拉尼亚克机场UFO(用于尾流涡危害缓解的超高速风传感器)项目的电子扫描雷达在雷达EDR检索和校准方面的试验。
