当以低超音速飞行时，升高的温度和顺风可以使音爆冲击波偏转，使其无法到达地面。这项工作提出了一种计算方法，结合了大气声波射线追踪、地形和真实的 3D 大气，以优化超音速陆上巡航的速度。使用多种大气条件在几个合适的城市对上模拟飞行任务。飞行时间和燃油消耗与亚音速高速任务进行了比较。
When flying at low supersonic speeds, rising temperatures and convenient winds can deflect the sonic boom shock waves so that they do not reach the ground. This work presents a computation methodology that incorporates atmospheric sonic ray tracing, topography, and realistic 3-D atmospheres in order to optimize supersonic overland cruise with respect to speed. Flight missions are simulated on several suitable city pairs using numerous atmospheric conditions. Flight times and fuel consumption are compared to subsonic high-speed missions.
