用火箭推进的

A technician straps legendary test pilot Scott Crossfield into the cockpit of the X-15 rocket plane before an early test flight. The X-15's maiden flight occurred on June 8, 1959,during which Crossfield was carried aloft in his sleek, black rocket plane beneath the wing of a B-52 from NASA's Flight Research Center.

在一次早期试飞中，一名技术专家用飞行皮带把传奇的试飞员斯科特克罗斯菲尔德固定在X-15火箭推进式飞机的小驾驶室中。1959.6.8，X-15进行了处女航，它挂在一架B-52超级空中堡垒的机翼下从NASA德莱登飞行研究中心起飞，克罗斯菲尔德驾驶着黑色光滑的火箭推进式飞机完成了处女航。

In boiler field, proper atomization of high viscosity liquid fuel is the essential assurance to safe .stable and high efficient combustion for boiler; in the propulsion equipment of rockers and turbo jet-propelled engine, the atomization quality of liquid fuel is the precondition to improve combustion efficiency and supply sufficient propulsion; in the field of industrial manufacture, metal powder is made by liquid metal which is impacted by high velocity gas; in the field of agricultural irrigation, the water with certain velocity is used to strike metal disk to make insufflations proportionally to the irrigation field; in the technique of desulphurization and coal gasification, proper design of nozzle is the essential factor to advance the efficiency of desulphurization and coal transformation.

在锅炉领域，高粘度液体燃料的良好雾化是锅炉安全稳定高效燃烧的重要保证；在火箭推进装置、涡轮喷气式发动机中，液体燃料的雾化质量是提高燃烧效率并产生足够推力的前提；在工业生产领域，用高速气流冲击液态金属来制备金属粉末：在农业灌溉中，用一定速度的水流冲击金属圆盘破碎并改变方向实现对灌溉区域的均匀喷洒：在烟气脱硫、煤气化等工艺中，良好的喷嘴设计是提高烟气脱硫效率和碳转化率的重要因素。
