基于风速的动态尾流间隔标准计算方法

Dynamic Wake Turbulences Interval Standard Calculation Based on Wind Speed

在保证安全的前提下压缩进场前后航空器间隔有助于提高机场容量,缓解拥堵情况。研究表明在逆风天气条件下能加快航空器尾涡的消散,同时在逆风天气条件下航空器的地速减小。这使得传统的基于距离的间隔标准存在提升潜力。欧美相关的科研机构和空管单位经过多年研究使用基于时间的间隔标准弥补基于距离的间隔标准在逆风条件下的不足。通过建立航空器进近阶段速度剖面计算所需飞行时间,统计机型和风速的分布并计算不同风速条件下采用基于时间的间隔标准对机场容量提升的效果。

On the premise of ensuring safety,we compress spacing between each arrival pair to help improve the airport capacity and relieve congestion.Studies have shown that aircraft wake turbulence can be accelerated dissipation under headwind conditions,at the same time,the ground speed of the aircraft is reduced under headwind conditions.This makes the traditional distance based separation standards have potential for improvement.European American research institutions and air traffic control units after years of research use time based separation offset the shortcomings of distance based separation standards under headwind conditions.Through establishing aircraft approach speed profile to calculate the required flight time.,statistical aircraft models and wind speed distribution to compute under different wind speed conditions using time based separation effect on airport capacity improvement.
