| Abstract: | The development of commercial aerospace launch vehicles at home and abroad and their rocket engines are reviewed. The propellant combinations such as liquid oxygen/methane, liquid oxygen/kerosene, and liquid oxygen/liquid hydrogen are comparatively studied. It is proposed that liquid oxygen/methane is the development trend and the best choice of commercial aerospace and future reusable liquid rocket engine. Based on the analysis of the trust selection principle of liquid rocket engine, it is determined that the thrust of the Land Space liquid oxygen/methane engine is 80 t and 8 t. Different kinds of power cycle modes such as gas-generator cycle, staged-combustion cycle, and expander cycle are compared, and the gas-generator cycle is selected as the technical scheme. Finally, the overall scheme, performance indices, technical innovation, applications, and research status of two types of liquid oxygen/methane engines of Land Space are introduced. |
