The vehicle has the following mission profile : vertical takeoff, boost-to-orbit, hypersonic re-entry and horizontal landing. 一般而言,可重复使用运载器的飞行任务剖面分为:垂直起飞、入轨、高超音速再入大气层、水平着陆(HL)几个阶段。
Considering the influences of acceleration, buffer journey and gradient, five-level buffer force is redesigned under utmost horizontal shock landing condition. 综合考虑加速度响应峰值、行程和缓冲力梯度的影响,在极限水平冲击工况下设计了新的五级分布缓冲力。
" It will be a fifth-generation aircraft with classic horizontal take-off and landing capability," the admiral said. “这将是第五代飞机的典型水平起飞和着陆的能力,”上将说。
Please put your armrest into horizontal position for landing. 降落时请将座位扶手放于水平位置。
