摘　　要：首先介绍了液体火箭发动机试验过程富燃气体的排出方式以及安全处理的必要性。文中总结了国内外最具代表性的液体火箭发动机试验冷氢排放处理所采用的高空排放、火炬烟囱和燃烧池三种不同方式的特点、工作原理和典型试验台的应用情况。重点介绍了惰性气体吹除、被动燃烧和主动燃烧三种富燃燃气安全处理方式及不同富燃燃气处理方式在不同试验台的应用情况。所总结的液体火箭发动机试验过程富燃气体安全处理相关技术可为大推力氢氧发动机试验台燃气安全处理研究提供借鉴。The necessity of fuel-rich gas exhausting mode and safety treatment during liquid rocket engine test is introduced. The key characteristics, operating principle and typical test bed application of high-altitude exhaust, flare stack and burning pool used for the most representative chilled hydrogen exhaust treatment at home and abroad in the process of liquid rocket engine test are summarized. Three fuel-rich gas safety treatment ways of inert gas blowdown, active combustion and passive combustion implied to different test beds are introduced emphatically. The fuel-rich gas safety treatment technologies used in the process of liquid rocket engine test are helpful to the safety treatment research of large thrust LOX/LH2 rocket engine test bed.
