【Abstract】 The performance, characteristic and development trend of the liquid apogee engine both domestic and abroad were described in this paper. The measures, including improving injector design, decreasing cool flow of boundary liquid film, adopting secondary burning and new material that can stand higher temperature, to promote the performance of the liquid apogee engine were given after the analysis methods to high impulse specific of the engine.更多还原
