Abstract
A sealing device including a retaining plate arranged in contact with an axial face of the rotor disc such that the retaining plate covers a gap between one of the retention grooves and the corresponding blade secured therein, along the axial direction; and a horn-shaped member protruding from the retaining plate and extending inside of an extrusion in the blade, the horn-shaped member having a first section seated against a complimentary surface inside the extrusion in the blade, wherein a center of gravity of the sealing device lies proximal to the first section of the horn-shaped member to cause the retaining plate to be pulled against the axial face of the rotor disc when the rotor disc is rotating, in order to secure the sealing device with the rotor disc.
Claims5
A sealing device for a rotor of a gas turbine engine, the rotor comprising a rotor disc with an annular array of retention grooves and a plurality of radially extending blades secured in the retention grooves, the sealing device comprising:
- a retaining plate arranged in contact with an axial face of the rotor disc such that the retaining plate covers a gap between the rotor disc and one of the blades secured in one of the retention grooves therein;
- and
- a horn-shaped member protruding from the retaining plate and extending inside of an extrusion in the blade, the horn-shaped member having a first section seated against a complimentary surface inside the extrusion in the blade,
- wherein a center of gravity of the sealing device lies proximal to the first section of the horn-shaped member to cause the retaining plate to be pulled against the axial face of the rotor disc when the rotor disc is rotating, to secure the sealing device with the rotor disc.
