摘要

通过高空舱内冷却空气流动与高空舱内外压差对发动机测力系统作用的分析

阐明了高空舱内次流和真空度对发动机台架测量推力影响的作用机理和本质差异

并从理论上论证了次流作用和真空度作用对测量推力影响的试验确定方法。

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.
