A blade root retaining system for attachment of a turbine blade to a turbine disc of a gas turbine engine comprises a blade root having at least one projection on each of opposite sides thereof, the projection extending from a leading edge to a trailing edge of the blade in an axial direction toward a longitudinal axis of the gas turbine engine. The blade root is received in an attachment slot defined through a periphery of the turbine disc. The attachment slot is configured in shape and direction for retaining the blade root.

Angled blade firtree retaining system

A rotor assembly for a gas turbine engine, the rotor assembly comprises a plurality of cooling air deflectors made integral with the rotor disk to redirect air to a manifold at a bottom side of a corresponding blade retention slot on the periphery of the rotor disk.

Rotor assembly with cooling air deflectors and method

An internally-cooled airfoil for a gas turbine engine, wherein the airfoil comprises at least one substantially chordwise-extending and internally-projecting stiffener located on an internal surface of one of the sidewalls and adjacent to the insert.

Internally cooled airfoil for a gas turbine engine and method

A rotor assembly for a gas turbine engine, the rotor assembly comprises a plurality of cooling air deflectors mounted on the rotor assembly to redirect air to a manifold at a bottom side of a corresponding blade retention slot on the periphery of the rotor disk.

An internally cooled turbine blade including at least one deflector extending into an air cavity generally from a first wall towards a second wall for diverting cooling air away from the first wall and generally towards the second wall to thereby improve cooling flow distribution among a plurality of cooling path inlets.
