The Development of High-Efficiency Turbine Blades

This document describes an experimental device as well as methods employed in and results obtained by measuring the flow of air through turbine stages. Experiments have been conducted using a single-stage turbine. Efficiency has been measured separately for stators equipped with prismatic, lean, compound lean and compound twist blade configuration. The loss coefficient has been determined for all four stator setups. The most suitable setup has been identified after comparing all available measurement results.
