摘要
三维大地形对空中飞行航迹有很大的影响,不同的飞行航迹在很大程度上影响空中交通流量(ATF)。以最优飞行航迹为背景,增大空中交通流量为目的,介绍了三维大地形模型的生成方法和步骤,并模拟出真实环境下的三维大地形模型。针对飞行路径对飞行航迹的影响,在该模型上加入影响飞行的其他自然要素,如能见度、风向风速、降雨量、云底高等。将此虚拟的飞行环境中生成的飞行航迹优化,尽量避免自然因素对飞行航迹的影响,优化之后相同时间段内通过相同航域的飞机架数增加了,从而增大了空中交通流量。
Three - dimensional terrain has great influence on the air flying trail, different flying trail affect ATF to a large degree. This article introduces the methods and steps for generating the large scale terrain models under the context of optimal flying trail and ATF. Considering the effect of flying path on the trail, some other natural factors are added to this model, such as visibility, speed and direction of wind, amount of rain, height of clouds and so forth. Optimizing the flying trail in this visual environment, which mostly avoids the impact of those natural elements. After optimization ,the number of planes coming through the same area increases thus increasing the ATF.
