管道火箭发动机可以提高未来战术导弹的射程和速度。在美国空军进行的关键发展阶段的验证试验中,休斯公司在模拟超音速导弹作变高度飞行的风洞中,成功地进行了固体管道火箭发动机的点火试验。管道火箭发动机是从大气中获得它所需要的大部分氧,而常规的空射 Pipeline rocket engines can improve the range and speed of future tactical missiles. In a validation test conducted by the U.S. Air Force at a crucial stage of development, Hughes successfully conducted an ignition test of a solid-pipeline rocket engine in a wind tunnel that simulated the supersonic missile’s flying at a high altitude. Pipeline rocket engines obtain most of the oxygen it needs from the atmosphere, while conventional air-shot
