turbine disc

turbine disc

turbine disc
The drum or the disc to which the turbine blades are attached. It is forged and then machined with an integral shaft or flange onto which the shaft may be bolted. To limit the effect of heat conduction from the turbine blades to the disc, a flow of cooling air is passed across both sides of each disc.
