Abstract
A turbine assembly ( ) for a gas turbine engine ( ) comprises a rotatable support arrangement ( ) which comprises means for mounting thereon a plurality of turbine blades ( ). The turbine assembly ( ) defines flow path means ( ) for a flow of cooling fluid therethrough. The flow path means ( ) is connectable to a supply of relatively cold cooling fluid. The flow path means is arranged such that the relatively cold cooling fluid is driven radially outwardly through the flow path means ( ) substantially wholly by the centrifugal force generated the rotation of the turbine assembly ( ) in operation. Relatively hot cooling fluid is displaced by the relatively cold cooling fluid radially inwardly through the flow path means ( ).
