| 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. |
