Abstract

Abstract

Through the analysis of the impact on engine thrust measurement system of both chamber cooling air flow and vacuum caused by the chamber internal and external pressure difference,both their action mechanisms and their essential distinction were clarified.Moreover,the test method for determining their impact on the engine thrust measurement system of the altitude simulated test facility was theoretically reasoned.
