Abstract: The constructure, performance, installation, test and test result of a high accuracy test bench for long-term solid rocket engines are described in detail. The test results show this type of bench safe, reliable, satisfactory in performance specified in standards, and well effective in operation.With this type of bench, the problem in high accuracy measurement of thrust for long-term SRE has been solved, which will improve the test technique and test reliability.
