Abstract:
The uncertainty source of the thrust measure system was determined on the basis of the working principle, composition, metrological standard value transitive relation and low temperature debugging result of thrust measurement system for a large thrust rocket engine. The test uncertainty of the thrust measurement system was assessed by error analysis and theory of error calculation. The test uncertainty of the system was obtained, which is taken as an evidence for accuracy of thrust measurement. The method can be taken as a reference for thrust measurement assessment for other types of rocket engines.
