Abstract

The invention relates to a turbofan engine control system and method based on a rapid prototype, and belongs to the technical field of engines. By means of the turbofan engine control system and method, the turbofan engine control system is established by using the universal rapid prototype, and various control functions such as engine oil supply, ignition and protection are achieved. Meanwhile, the system has good versatility, strong expandability, the short development cycle and low cost, is suitable for the rapid development of engine control systems in the early development stage, can greatly reduce the development cost and can shorten the development cycle.

Description

Technical field [0001] The invention belongs to the technical field of engines, and in particular relates to a turbofan engine control system and method based on a rapid prototype machine. Background technique [0002] The engine control system is the core component of the turbofan engine, which is used to achieve functions such as engine control law calculation, fuel control, and ignition control. The traditional turbofan engine control system is developed with the electronic controller as the core, but the development of a dedicated engine electronic controller has high cost, long cycle and poor versatility, which cannot meet the needs of rapid engine development. Summary of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is: how to design a turbofan engine control system and method that can satisfy multiple engine control functions. [0005] (2) Technical solution [0006] In order to solve the above t...
