Key turbomachinery technology of civil high-bypass-ratio turbofan engine

The research progress on partial turbomachinery technology of high-bypass-ratio turbofan engine were reviewed and analyzed in the present study and the partial key technology of turbomachinery required for our country's high-bypass-ratio turbofan engine were also expatiated. The main contents included four aspects: fan/compressor design technique, turbine design technique, flow and noise control and multi-disciplinary coupling technique.
