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:
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.
Abstract:
A turbine engine assembly arranged relative to an axis includes a rotor blade and a feather seal with an L-shaped geometry. The rotor blade includes an airfoil and a base. The airfoil extends axially between an upstream leading edge and a downstream trailing edge, and radially out from the base. The base includes a neck and a pocket. The neck extends axially to a downstream surface. The pocket extends laterally into the neck. The feather seal extends laterally into the pocket, and includes a down stream leg that extends substantially along the downstream surface.
Abstract:
A nozzle segment for a gas turbine engine includes an arcuate outer vane platform segment. An arcuate inner vane platform segment spaced from the arcuate outer vane platform segment. A multiple of airfoils between the arcuate inner vane platform segment and the arcuate outer vane platform segment, the arcuate outer vane platform segment includes a scallop slot and a seal that seals the scallop slot.
