摘　　要：在一项特殊要求、非例常的试验中,需发动机进行接力试车:在同一次试车中前后两个阶段分别使用两个不同厂家的氧化剂,在进行氧化剂切换时,发动机连续工作,即进行接力试车。为此,在原试车台试验系统的基础上,进行了必要的技术改造,建立了试车台发动机接力试车氧化剂试验系统。经热试车验证,改造后的系统工作安全可靠,满足发动机接力试验要求。A liquid rocket engine relayed test had to be conducted on a conventional test stand, in which oxidizers from different plants were required to be used without shut-down of the engine for the purpose of checking the performances of the oxidizers. Thus, the original test stand had to be modified and a new oxidizer test system was established for relayed test. The key technology resolved during the relayed test is described in the paper. Hot test proved that the modified system operated reliably and safely. All the engine test requirements were met very well.
