Abstract
An air-cooled component such as a turbine stator vane, has a row of cooling passages extending from the interior of the vane to the exterior. The passages are inclined to a plane perpendicular to the row. The angle of inclination of each passage varies with the position of the passage along the row. The arrangement assists in avoiding local overheating of the vane surface.
Claims10
An air-cooled component having a wall provided with cooling passages extending through the wall, the cooling passages being disposed in a row, whereby the angle between each passage and a plane perpendicular to the direction of the row varies with the position of the passage along the row, the passages being disposed in two groups, extending in opposite directions from a common point along the row, the passages in each group being inclined to the said plane in the opposite sense from those in the other group, the component having a hollow aerofoil portion, the passages extending from the interior of the aerofoil portion to the exterior of the component, wherein an internal partition is disposed within the interior of the aerofoil portion, substantially at the level of the common point.
