Abstract

An analytical method for constructing profiles of radial blades of turbine stages is proposed. The profile is set in a curvilinear coordinate system, consists of input and output edges, as well as suction and pressure sides described by the 5th and 4th order curves, respectively. An example of a high-loaded radial-axial stage with a profile of a new type of stator, the use of which has significantly improved the aerodynamic characteristics of the flow path, is considered.

 

Keywords: radial-axial turbine, high-loaded stage, flow path, analytical method of profiling, spatial flow, numerical modeling
