Abstract
PURPOSE: In a turbine blade having specific area wherein a fluid running along the surface on a negative pressure side is decelerated, to pevent a damage of the turbine blade during transonic operation by permitting the fluid to pass through it from the negative pressure surface in the decelerating area.
CONSTITUTION: A blade P having a negative pressure side C and a pressure side D is moved in the direction R. Several hiles E are made through up to a decelerating area W on the negative pressure side C. As a fluid flows through the holes E, a pressure difference may be reduced between the pressure and negative prssure surfaces created when a shock wave runs against the decelerating area on the negative pressure side. Additionally, the shock wave is prevented from making severe vibration on this area, resulting in an application of a seriously fluctuating pressure on the blade P, and thus, a damage of the blade P can be prevented.
