1995年以后的科学和军事空间任务需要将一个结构庞大、有效载荷重的空间站输送到低地球轨道上.但目前的空间运载系统满足不了这一要求,因此,Visek,W.A.提出了一种新的助推发动机方案(见图1,2).在液氧/碳氢助推发动机中输入液氢不仅可以冷却推力室,驱动燃气发生器,而且可以稳定和改善燃烧性能.这可以大大消除设计人员在高压、重复性使用助推发动机中应用碳氢燃料时的风险.这一方案在低成本条件下可提高飞行器性能并为工作适应性创造了条件.
The scientific and military space mandate after 1995 required the transport of a large, payload-loaded space station to low Earth orbit, but current space delivery systems do not meet this requirement and Visek, WA has proposed a new Booster engine program (see Figures 1 and 2.) Inputting liquid hydrogen into a liquid oxygen / hydrocarbon boost engine not only cools the thrust chamber and drives the gas generator, but also stabilizes and improves combustion performance, which substantially eliminates the need for designers The risk of using hydrocarbon fuels in high-pressure, repetitive-use booster engines. This solution can improve aircraft performance at low cost and create conditions for workability.
