Abstract: PROBLEM TO BE SOLVED: To provide a cooling system for a turbine airfoil provided with pedestals having an ice-cream-cone-shape or teardrop-shape.SOLUTION: The turbine airfoil includes a wall portion, a cooling channel, a plurality of trip strips and a plurality of pedestals. The wall portion includes a leading edge, a trailing edge, a positive pressure side and a negative pressure side. The cooling channel is for receiving cooling air and extends radially through an interior of the wall portion between the pressure side and the suction side. The plurality of trip strips line the wall portion inside the cooling channel along the pressure side and the suction side. Each of the pedestals is an elongate, tapered pedestal having a curved leading edge. The plurality of pedestals is interposed within the trip strips and connects the pressure side with the suction side.

Abstract: A turbine engine component (12) such as a turbine blade includes an airfoil portion (10) formed by a suction side wall and a pressure side wall, and a cooling microcircuit (14) incorporated in at least one of the suction side wall and the pressure side wall. The cooling microcircuit (14) comprises a channel (11) through which a cooling fluid flows, at least one exit hole (18) for distributing cooling fluid over a surface of the turbine blade, and internal features within the channel (11) for accelerating the flow of cooling fluid prior to the cooling fluid flowing through the at least one exit hole (18).

Abstract: Se proporciona una paleta de turbina para un motor de turbina de gas con enfriamiento mejorado en una porción radialmente externa del borde de salida. Se proporciona una ruta de bandera de punta con un primer arreglo de pedestal para incrementar la transferencia de calor en el área. Además, un segundo arreglo de pedestal reemplaza los agujeros de dosificación que han sido colocados radialmente hacia adentro de la tira de punta. Los dos arreglos de pedestal proporcionan transferencia de calor mejorada en un área que ha sido sometida a la quema y estalación en la técnica previa.

Abstract: A passageway is provided through which a cooling fluid flows in a first direction. The passageway has a plurality of trip strips positioned within the passageway. Adjacent one of the trip strips are oriented to converge towards each other at a first end to form an apex portion and to form a region in which turbulence is created. The apex portion is oriented at an angle with respect to the first direction.

Abstract: A passageway (102) is provided through which a cooling fluid flows in a first direction (104). The passageway (102) has a plurality of trip strips (106) positioned within the passageway (102). Adjacent one of the trip strips (106) are oriented to converge towards each other at a first end to form an apex portion (108) and to form a region (112) in which turbulence is created. The apex portion (108) is oriented at an angle with respect to the first direction (104).

Abstract: TURBINE COMPONENT WITH TIP FLAGGED PEDESTAL COOLING A turbine blade for a gas turbine engine is provided with improved cooling at a radially outer portion of the trailing edge. A tip flag path is provided with a first pedestal array to increase the heat transfer at the area. In addition, a second pedestal array replaces the metering holes which has been positioned radially inwardly of the tip strip. The two pedestal arrays provide improved heat transfer at an area which has been subject to burning and spallation in the prior art.
