Abstract

The present disclosure relates to a modeling method for a turbofan engine. The method comprises the following steps: the state of the test data of a plurality of test points of a turbofan engine is transformed to obtain a test point data set under a target test state; Screening the data in the test point data set to obtain a screening test point data set; Aero-thermodynamic model is constructed according to the data set of screening test points. According to the actual measured parameters, the aero-thermodynamic model is obtained by trial-and-error analysis of several trial-and-error iterativeparameters in turn. Calibrating the trial-and-error aerothermodynamic model to obtain the calibrated aerothermodynamic model; The calibrated aerothermodynamic model is modified to obtain the target aerothermodynamic model. The modeling method of the turbofan engine provided by the embodiment of the present disclosure has the advantages of short construction period, small error of the constructedmodel and high accuracy.

Description

technical field [0001] The present disclosure relates to the technical field of turbofan engines, in particular to a modeling method of turbofan engines. Background technique [0002] Aerodynamic thermodynamic mathematical models of turbofan engines and other aero-engines are important tools for evaluating and predicting the performance of aero-engines under different flight conditions. In related technologies, the establishment of an aerodynamic and thermodynamic mathematical model of an aeroengine depends on a large amount of component test characteristic data, and the established model has problems such as large errors and low precision. Contents of the invention [0003] In view of this, the present disclosure proposes a turbofan engine modeling method to solve the problems of large errors and low accuracy of the aerodynamic thermodynamic model of the turbofan engine. [0004] According to a first aspect of the present disclosure, a modeling method of a turbofan engin...
