Abstract:

For studying the method of cycle parameters design optimization of turbofan engine, an integrated optimization design model of multi-role fighters and turbofan engines is presented, and the computer program based on the model is developed. The model includes a bivariate controlled turbofan engine performance computing model, installed performance computing model, fighter dynamic analysis model, weight composing analysis model, mission profile analysis model, constraint and mission analysis model, and optimization computing model, etc.
