燃气分析法测量喷气推力的探讨
A JET THRUST MEASUREMENT METHOD WITH GAS COMPOSITION ANALYSIS
-
摘要: 通常测量发动机的喷气推力,是在试车台架上用机械方法进行,离开试车台架,例如在机场或在飞行中,无法知道各种情况下推力的变化。Abstract: A new method is proposed which uses composition analysis of gas from engine for determining jet thrust at a given fuel consupmtion. This method has been verified in JT15D engine testing, and the thrust error is about 6.9%.
