[0002] The aero-engine control software is difficult to effectively guarantee the consistency of manufacturing and assembly of the control object aero-engine, and a large number of adjustable parameters need to be set in the control software in order to fully exert and verify the engine performance, which are used to change the control parameters of the engine in different states, so as to guarantee the consistency of performance or further improve the performance.

[0003] In the development and maintenance process of the aero-engine control software, it is inevitable to code the adjustable parameters based on documents, and a large number of adjustable parameters also need to be prepared into parameter data item files in a specified format.

Therefore, it is necessary to adopt a componentized development method to guarantee that no omission and error of parameters occur in the whole development process and the life cycle maintenance process.
