document: Innovative manufacture of impulse turbine blades for wave energy power conversion An innovative approach to the manufacture of impulse turbine blades using rapid prototyping , fused decomposition modelling -LRB- FDM -RRB- , is presented . These blades were designed and manufactured by the Wave Energy Research Team -LRB- WERT -RRB- at the University of Limerick for the experimental analysis of a 0.6 m impulse turbine with fixed guide vanes for wave energy power conversion . The computer aided design/manufacture -LRB- CAD/CAM -RRB- package Pro-Engineer 2000i was used for three-dimensional solid modelling of the individual blades . A detailed finite element analysis of the blades under centrifugal loads was performed using Pro-Mechanica . based on this analysis and FDM machine capabilities , blades were redesigned . Finally , Pro-E data were transferred to an FDM machine for the manufacture of turbine blades . The objective of this paper is to present the innovative method used to design , modify and manufacture blades in a time and cost effective manner using a concurrent engineering approach
