Research on a High Work Axial Gas Generator Turbine 800618

A previous phase of the Canadian government and in-house sponsored turbine research program established guide lines for the current design of a high-work axial gas turbine, capable of operating at a high total pressure ratio of 3.9. Aerodynamic results from tests on this research ·turbine are presented in this paper. A number of variants of this basic design was also tested, which indicated the effect on aerodynamic performance of geometric changes such as vane tangential lean, rotor tip partial shrouds and tip clearance.
