Based on the coupled design and computation models of both engine and components,this paper presents a compositive methodology of the whole engine design considering the difficulty coefficients,which reflect the technology maturity levels,and creates the digit model through deep studying the interconnections among the engine performances,flow path size and component weights under the constraints from aerodynamic loads,stress loads and dimensions.The model is validated by the related data from a turboshaft engine,the simulation error of which is evidenced to be acceptable.
