发动机试验稳态性能分析和评定方法

本文先简单介绍了发动机稳态性能的确定方法,然后讨论了节流特性和高度-速度特性变化的影响因素,并给出了这些特性的分析和评定方法,最后用这些方法分析了某型发动机的地面节流特性和高度-速度特性验证试验的试验结果.研究结果表明,本文所述的方法不仅可以提供比较准确的评定结果,而且有助于分析差异产生的原因.

The Analytical and Assessment Method of Steady Performance in Engine Test

This paper briefly introduced the metbods of determining engine steady state performance, the factors affecting throtlle performance and altitude-velocity performanee and provided file analytical and assessment methods. Finally, engine test data obtained from ground throttle test and altitude simulation test were analyzed with these methods. The results shown that the methods will provide a reliable assessment and assist to find out the reasons of the performance difference.
