A component 14 comprises a multiplicity of cooling passages arranged in two intersecting arrays to form a multiplicity of cooling passage intersections 40. Air jet interactions are generated at cooling passage intersections when air is passed through the cooling passages. The spacing of the passages in at least one of the arrays is chosen to provide a predetermined range of intersection density in a selected region or regions 30,32,34 of the component. The component may be a turbine aerofoil of a gas turbine engine. |
