日本宇宙科学研究所的专家研制成功一种用水作燃料的新型激光推进器 ,可望成为宇宙轨道间运输器等宇航工具的发动机。这种激光推进器的主要部分由管状的燃料水容器和安在容器前部的喷嘴组成 ,形成水从喷嘴中逐渐喷出的结构。在模拟宇宙空间的真空试验槽内的试验表明 ,当外部的?
The experts of Japan Institute of Astronautics successfully developed a new type of laser thruster that uses water as fuel and is expected to become the engine of spacecraft such as space orbital transporter. The main part of this laser thruster consists of a tubular fuel water tank and a nozzle mounted in front of the tank to form a structure where water is gradually ejected from the nozzle. Experiments in a vacuum test tank simulating cosmic space show that when external?
