| Abstract: | A development system is presented based on one-dimensional thermal design,quasi-three-dimensional design analysis and optimization,full-three-dimensional CFD analysis and blade design,strength and vibration analysis.With the aid of air-cooled low pressure stage turbine design,the turbine can be easily and reliably designed and optimized by means of the development system,which shows a good practical sense for turbine design and development. |
