Abstract

The invention belongs to the field of aero-engine design, and particularly relates to an aero-engine starting simulation model correction method based on test data, and the method comprises the steps: calculating a correction value under a preset condition, and carrying out the simulation calculation of the calculated correction value to obtain a simulation correction value under a target condition, and calculating the rotating speed under the target condition through the obtained correction value. By adopting the method, the starting simulation precision can be greatly improved, the maximum error of high-voltage and low-voltage rotating speed simulation and actual comparison is within 6.9%, and the engineering precision requirement is met.

Description

technical field [0001] The application belongs to the field of aero-engine design, in particular to an aero-engine starting simulation model correction method based on test data. Background technique [0002] Numerical simulation of aero-engine starting is an important method for the study of engine starting process, and it is very necessary to establish a simulation model for engine starting. Starting simulation is an important means to promote the change of aero-engine starting performance design from "traditional design" to "predictive design". The repetition of physical tests shortens the development cycle, reduces development costs, and effectively accelerates the independent innovation and development of my country's aero-engines. [0003] The starting simulation model can calculate the starting characteristics of the engine within the entire starting envelope range with a certain accuracy, and can be used for starting simulation and starting performance design within ...
