| Abstract: | For improvement of thrust level measurment accuracy of liquid rocket engine, measurement system modification was conducted. The previously used strain-beam system was replaced by dual-curved-beam measuring system. System modification measures and application results were introduced in this paper. Test results show that the dual-curved-beam measuring system has higher accuracy and better enviornment adaptability. |
