A methodology was proposed to develop generic aero-engine simulation platform by using software componentization.From the point of view of the engine construction engine model was broken down into several components

from the point of view of software functions the supplementary part of the simulation software was also broken down into multiple components.And a simulation platform of turbofan engines was established

which had achieved good effect.The simulation system based on this method had achieved to be modular

hierarchical

and easy to be maintained and improved.It has strong expandability

and has increased code reuse rate

which reflects the flexibility of the framework of the simulation platform.
