据3月30日出版的美国《航空周刊》报道,俄罗斯科学家3年前开始设计的一种使用液氧、氢和煤油作燃料的宇宙火箭,现已完成了该项目80％的设计蓝图绘制工作。按照原苏联科学家,即现在俄罗斯科学家的设想,这种新型火箭将拥有两台涡轮泵、两个主燃烧室和安装在双轴万向节系统上的两个发动机尾喷管。它的推力可达408吨,有效载荷的运载能力可比单纯使用液氧和氢的现有同等规模火箭大一倍。火箭上的一台涡轮泵将把液氧和煤油泵入一个预热室内,以产生加
According to the March 30 issue of the United States, “Aviation Week” reported that Russian scientists started three years ago designed using liquid oxygen, hydrogen and kerosene fuel for the space rocket, has completed 80% of the project blueprint for the design work . Based on the ideas of former Soviet scientists, now Russian scientists, the new rocket will have two turbo pumps, two main combustion chambers and two engine tail nozzles mounted on a two-axle universal joint system. It has a thrust of 408 tons and its payload capacity is twice as large as the existing rockets of the same size that use liquid oxygen and hydrogen alone. A turbo-pump on the rocket will pump liquid oxygen and kerosene into a preheating chamber to create a boost
