摘要
将数值分析方法应用于飞机发动机稳定性评定。考虑使用因素对发动机部件特性的影响,计算分析了发动机稳态时喘振裕度的变化,获得了使用因素对发动机喘振裕度的影响结果。研究表明,发动机数字仿真技术应用于稳定性评定是可行的,所研究的数值分析方法可进一步应用于发动机稳定性评估。
A numerical analysis method for aero gas turbine engine stability assessment is presented in this paper. Based on the characteristics of acre-engine components in operation, aerodynamic stability of a turbo-jet engine was analyzed and the influence of the coefficients upon the aerodynamic stability was obtained. The calculation results show that operating conditions and component characteristics have significant effects on aero-engine stability assess- ment. This method can not only give reasonable prediction but also reliable results for engineering applications.
