Turbine rotor disk with integral blade cooling air slots and pumping vanes
TL;DR: A rotor disk for a gas turbine engine includes a central loadbearing web portion (70) and a centrifugal pump (62) portion located externally of the load-bearing web component for pumping cooling air into an array of turbine blades as mentioned in this paper.
Patent
Methods and apparatus for directing airflow to a compressor bore
TL;DR: A gas turbine engine includes a compressor rotor assembly which directs air at a sufficent pressure and temperature to a turbine rotor bore as mentioned in this paper, where the vanes effectively deswirl bleed air and re-direct the airflow to a compressor bore.

Apparatus for attaching tubing to a rotating disk
TL;DR: In this article, a rotating member of a turbine disk is provided with an axially extending retaining means such as a ring having a plurality of D-shaped, open-ended slots formed about an edge thereof.
Patent
Turbine blade cooling
TL;DR: In this article, an arrangement for supplying coolant flow to turbine blades in a gas turbine engine is disclosed which utilises a preswirl assembly to impart a tangential velocity to the coolingant flow substantially greater than the tangential velocities of the rotor at the point at which the air is supplied to the rotor.
