The research group headed by Mr. Han Song Ho, researcher of the Faculty of Mechanical Science & Technology developed a new x-type runner, thus making a great contribution to increasing the electric power in the hydraulic power stations.
Through their painstaking efforts of 10 years, they made an efficient decision of characteristics of inlet edge, blade section, blade head propel and outlet, by scientifically analyzing disadvantage of conventional runner, thereby developing a new x-type runner of which the hydraulic turbine has maximum efficiency over 2 % higher and work efficiency over 4% higher.
