Abstract: This paper presents new computer automated techniques for the design, analysis and manufacture of Kaplan turbine blades. The inlet flow field was determined using the finite element program 'ANTHONY'. The direct fluid dynamic design of the blade was executed using the two-dimensional singularities program 'INNA'. The final runner design was analyzed at off design points using the two-dimensional singularities program 'ALHAL'. The cavitation characteristics are included in 'INNA' and 'ALHAL' outputs. The profile losses were determined by the two-dimensional boundary layer program 'DEBRA'. The model test results of cavitation and performance characteristics agreed well with the theoretical prediction at the design point.
