Abstract
An apparatus and method an engine component for a turbine engine comprising an outer wall bounding an interior and defining a pressure side and an opposing suction side, with both sides extending between a leading edge and a trailing edge to define a chord-wise direction, and extending between a root and a tip to define a span-wise direction, at least one cooling passage located within the interior, at least one cooling hole having an inlet fluidly coupled to the cooling passage and an outlet located along the outer wall.
Claims20
A component for a turbine engine, which generates a hot gas flow, and provides a cooling fluid flow, comprising:
- a wall separating the hot gas flow from the cooling fluid flow and having a heated surface along which the hot gas flows and a cooled surface facing the cooling fluid flow;
- and
- at least one cooling hole comprising at least one inlet at the cooled surface, at least one outlet at the heated surface, at least one connecting passage extending between the at least one inlet and the at least one outlet, with an impingement cavity formed in the at least one connecting passage, the at least one connecting passage including a first portion upstream of the impingement cavity and a second portion downstream of the impingement cavity, the second portion having an inverse diffusing section with a converging section having a cross-sectional area defining a first dimension and a second dimension perpendicular to the first dimension, the second dimension decreasing toward the at least one outlet;
- wherein the impingement cavity has a height oriented in a same direction as the first dimension and a width oriented in the same direction as the second dimension, where the width is greater than the height.

- a first portion extending in a first direction having a first cross-sectional area defining a first centerline,
- a second portion extending in a second direction different than the first direction and having a second cross-sectional area defining a second centerline, the second cross-sectional area defining a first dimension perpendicular to the second centerline and a second dimension parallel to the second centerline,
- a turn located between the first portion and the second portion and defining an impingement cavity, and
- a diffusing section located in the first portion with the first cross-sectional area increasing in the first direction toward the turn,
- wherein the impingement cavity is a disc-shaped impingement cavity having a height oriented in a same direction as the first dimension and a width oriented in the same direction as the second dimension, where the width is greater than the height.
