Turbine discs Discs are usually manufactured from a machined forging with an integral shaft or with a flange onto which the shaft may be bolted. The disc also has, around its perimeter, provision for the attachment of the turbine blades. The discs are cooled on both sides to limit conduction from the bladesTiAl low-pressure turbine blades. At present the production of TiAl blades is delayed primarily due to cost considerations [3].
