文中简单回顾了单级入轨运载器的发展历史 ,指出垂直发射单级入轨火箭运载器存在严重的缺点是 ,运载效率低下 ,技术途径充满风险。论证了水平发射单级入轨火箭运载器的可行性。认为水平发射是提高单级入轨火箭运载器运载效率的重要途径 ,亦是在技术上比较容易实现的技术途径

[The development history of the vehicle of single stage to orbit is reviewed simply in this paper. It must be indicated that the vertical launch of the vehicle of single stage to orbit has serious shortcomings. This is a technical way of inferior launch efficiency and brimming with risk. The feasibility of horizontal launch of the vehicle of single stage to orbit is discussed. It is holded that the horizontal launch is a very important way of increasing launch efficiency of the vehicle of single stage to orbit. And this is also easy to be achieved in technology.]
