Analysis of the Effects of Parameter Small Deviations on a High Thrust-Weight Ratio Aeroengine Performance
-
摘要: 依据小偏差法原理,针对涡扇发动机的工作特点,计算并分析了发动机过程参数及评定发动机各主要部件损失的系数等14个参数的小偏差对某高推重比航空发动机性能的影响,为某高推重比航空发动机设计过程中,如何调整某些参数补偿某另一参数的偏差对发动机性能的影响提供依据,同时为航空发动机的技术发展提供定量的指导作用。Abstract: Based on method theory,considering the turbofan engine working characteristics,effects of the parameter small deviations on performance of a high thrust-weight ratio aeroengine were calculated and analyzed.This analysis included 14 engine working process parameters and coefficients assessing primary engine components.This research provides foundations of how to adjust parameter values to compensate effects of other parameter small deviations on aeroengine performance in the process of aeroengine design and also provides quantitative guidance for aeroengine technical development.
