Abstract : The paper brings together some of the main conclusions drawn from recent work in an on-going experimental program of research on teh aerodynamics of a highly loaded turbine stage. Detailed data have been secured relating to the aerodynamic performance of transonic nozzles of high turning angle (tested with two different outer wall contours) and the influence of the stage environment on such measurements. Further work addressed rotor performance (as affected by blade loading), and also overall stage performance. The ultimate objective of the work is the extension of turbine design methods to regimes combining high stage loadings with high pressure ratios, with special emphasis on small blade sizes.
