Turbine wheel for high speed rotary tools

The turbine wheel has blades (2) with axially parallel front and rear surfaces (3, 4) and are radially curved. The radially outer sectors of the front surface (3a, 4a) are of smaller curve radius (R2, R4) than the inner sectors (3b, 4b). The front surface, at least in sectors, has a smaller curve ra...

Summary:The turbine wheel has blades (2) with axially parallel front and rear surfaces (3, 4) and are radially curved. The radially outer sectors of the front surface (3a, 4a) are of smaller curve radius (R2, R4) than the inner sectors (3b, 4b). The front surface, at least in sectors, has a smaller curve radius than the rear surface.
