Abstract

The purpose of this paper is to present advances in Reaction Technology Blading design for large steam turbines at Low Aspect Ratio, based on ‘Controlled Flow 2-type’ technology. Reaction technology blading has not previously been evaluated like the impulse blading for improvements from advanced aerodynamic technologies. This paper identifies several unique design improvements and validated by advanced analytical modelling and model turbine testing.
