WANG Bin,WU Xiao-song,YU Ling,WANG Dong(School of Mechanical Engineering,NUST,Nanjing 210094,China)  
This paper analyzes main problems involved in the design of rocket engine test-bed with high-speed rotation,including the layout design,the choice of drive method,the design of axes and assembly,the choice and installation of sensors.The result shows that the new improved designing layout is practical and realize the coinstantaneous measurement of propulsion and pressure in a high-speed rotation situation.The design solves the hermetic problem,reduces the vibration and noises,improves the application and maintenance performance of the test-bed.
