Abstract

An approximation method for simulating the low speed

low flow characteristics of axial flow fan

high-pressure compressors and high-/low-pressure turbines were presented

based on their high-speed characteristic maps and design point parameters of the engine.With the component matching technology of turbofan engines

a calculation model and corresponding algorithm for the start-up process of a certain turbofan engine was set up

thereby providing rational simulation results for the start-up process of engine.
