Abstract

A turbine blade such as a rotor blade or stator vane in a gas turbine engine is provided of the type having an internal flow path for flow-through passage of a cooling gas stream, wherein the turbine blade includes a heat transfer surface designed for improved heat transfer with the cooling gas. The heat transfer surface comprises a regular pattern of turbulator vanes which extend generally transversely to the flow direction of the cooling gas stream, in combination with comparatively shorter heat transfer ribs which extend generally parallel to the gas stream flow direction. The pattern of turbulator vanes and heat transfer ribs provides significantly improved heat transfer between the turbine blade and the cooling gas stream, such that the cooling flow requirement is reduced to result in increased engine efficiency.
