摘要
Abstract
The bleed, natural recirculation and forced recirculation preeooling methods used in cryogenic propellant rocket engine in domestic and aboard were summarized in this paper. The research on the precooling of new cryogenic propellant rocket engine for the new generation launch vehicle in China was introduced. The key factors of propellant type, the sub-stage of the engine and multifactor integrated of natural recirculation which affected the precooling scheme, and the key technologies such as the maintaining and boiling heat transfer and two- phase flow numerical simulation were discussed.关键词
