Abstract
A turbine assembly for a gas turbine engine includes a plurality of turbine blades ( ) mounted on a rotatable support means in the form of a turbine disc so as to extend radially therefrom. The turbine blades include circumferentially extending blade platforms ( ) spaced from the turbine disc and means are provided for allowing the passage of air between an internal region of the blades ( ) and a space located between the blade platforms ( ) and the turbine disc. The air may flow out of and back into the same turbine blade, or may flow into an adjacent blade. This flow of air results in the cooling of the blade platforms ( ).
