摘要
提出一种新的巡航飞行方式,在地球表面的垂直方向上,利用离心力,辅之火箭推力,平衡重力,以保持飞行高度;在地球表面的平行方向上,依靠助推段获得的速度,惯性前进.这种飞行方式适合于高空稀薄气体环境,可将高超声速巡航飞行高度从传统的30km附近拓展到100km附近.
A new kind of cruise flight has been proposed. Along the direction perpendicular to the earth surface, the centrifugal force and rocket thrust are used to resist the force of gravity and maintain the flight altitude, while in the direction parallel to the earth surface to go forward by inertia at the speed obtained during the boost stage. The kind of flight, suitable to high altitude and low-density air environment, extends the cruise flight altitude from traditionally about 30 km to around 100 km.
