WANG Fei,WANG Lian-lai,DONG Zhi-bin,LIU Guang-chu(The Second Engineering Scientific Research Institute of the General Armaments Department,Beijing 100093,China)  
In order to judge whether solid engine performance meets product charts and technical terms,and to have credible evaluation about safe storage,a thrust measuring system of solid rocket engine was studied.Using this system,the working time and thrust of solid engine of 50~310 mm caliber were measured,and data acquisition system adopted GJB770A-97 engine quiescence testing method.Real equip tests show that engine assemblage,engine fire and data acquisition are effective and efficient,and data of thrust-time figure accord to the facts.Test results show that this system can meet the current needs of measuring thrust of solid rocket engine.
