| 摘 要： | 针对民用大涵道比涡扇发动机的设计特点,基于部件一维气动设计结果,分别建立高压压气机叶片(增压级、中压压气机叶片重量估算模型与高压压气机叶片相同)、风扇叶片重量估算模型:通过简化高压压气机叶片结构,采用等效厚度、气动修正因子等方法,建立了基于统计分析法的高压压气机叶片重量估算模型;通过分段简化风扇叶片结构,采用弦长、最大厚度拟合规律及分段求解体积等方法,建立了基于统计分析法的风扇叶片重量估算模型。

| Abstract: | Based on 1-D aerodynamic design, weight estimation models for high pressure compressor blade and fan blade were established separately in view of the characteristics of civil turbofan engine with large bypass ratio.Simplified structure, equivalent thickness and aerodynamic correction coefficient were used to establish weight estimation model for high pressure compressor blade based on statistic analysis. Simplified structure in subsection,chord and max thickness matching were used to establish weight estimation model for fan blades based on statistic analysis. |
