Abstract: The invention comprises sealing structure between a seal plate, a rotor, and a blade, for sealing the root portion of a rotor and blade assembly to provide a sealed chamber adjacent the base of the root into which radially directed passageways in the blade open for transmitting the cooling fluid, delivered to the chamber, through the blade to the tip end thereof to cool the blade. The seal is perfected through a wedging action caused by centrifugal force moving the base or foot of the plate, disposed below the blade root, into sealing engagement with the rotor disk, and an intermediately disposed seal bar extending arcuately just radially outwardly of the radially innermost portion of the root and generally in the vicinity of the innermost loaded root projection with the loaded root providing the axial seal and the sealing bar and seal plate foot providing the radial seals to define a cooling fluid chamber adjacent the base of the root.

Abstract: In order to prevent axial movement of blades with respect to their rotor, a locking ring is provided which abuts the blades and is mounted from the disc by a bayonet connection. The blades engage with the ring to prevent its rotation with respect to the disc and consequent disconnection.

Abstract: A turbine rotor construction in which the disk has radially extending tubes on which ceramic blades are slidable, and the centrifugal load on the blades is carried by an external filament wound ring surrounding and engaging the outer ends of the row of blades.

Abstract: A rotor wheel including a hub in the form of a thin-walled shell. Rotor blades are arranged in an annular pattern around the axis of the hub, each blade having at least one blade root formed with a hole. A pin extends through the hole in each blade root, and at least one retaining ring coaxial with the hub axis surrounds all the pins and absorbs radial forces produced by the blades on the pins when the rotor wheel rotates. The retaining rings and blades are fixed against axial and circumferential movement with respect to the hub. A segment between each pin and retaining ring distributes the forces of the pin to the retaining ring. The pins are mounted for radial movement with respect to the hub, and one of the mounting parts for said pins may be detachable from the hub. The hub may be dish shaped, and the pins secured at only one end to the peripheral wall of the hub, that wall having axial slots so that it may expand radially.

Abstract: In an axial flow compressor rotor stage having a tangential slot in the periphery of the rotor to receive the blade roots, a seal is positioned below the blade platforms to seal these platforms against air recirculation. The seal extends under the platforms of several blades and is ladder shaped with the rungs sealing the platform spaces and the struts serving to interconnect and hold the rungs in place.
