Abstract

A component, such as a turbine blade of a gas turbine engine, has an internal cooling system which includes a passage () having a passage inlet () and a passage exit (), which may be in the form of passageways at or adjacent to the trailing edge of the component. The passage () is divided into chambers () by partitions () which extend from one wall () of the component and terminate short of the opposite wall () to provide gaps () to permit chord-wise cooling air flow from the passage inlet () to the passage exit (). The gaps () force the cooling air to pass adjacent the hot walls (), so increasing the heat transfer coefficient between the cooling air and the material of the component.
