ABSTRACT:
A coolable nozzle guide vane in the turbine section of a gas turbine engine is disclosed. The vane has a platform section and an airfoil section which are adapted to receive and distribute cooling air about the walls of the sections which are in contact with the hot working medium gases flowing through the turbine during operation of the engine. Impingement cooling and transpiration cooling techniques are combined to maximize the cooling effectiveness of the air supplied.
