20110176925 | TORSIONAL FLEXING ENERGY ABSORBING BLADE LOCK - A lock for constraining blades in a hub includes a flexible ring for constraining the blades from moving axially in the hub, a finger attached to the hub for preventing the ring from rotating relative to the hub and whereby the ring flexes about at least a partial circumference thereof if urged axially by the blades. | 07-21-2011 |
20130052026 | AXIAL RETENTION SYSTEM FOR A BLADED ROTOR WITH MULTIPLE BLADE TYPES - A bladed rotor includes a blade lock mountable to a rotor hub adjacent to a multiple of blade slots. The blade lock includes at least one interface feature adjacent to a first of the multiple of blade slots. A first rotor blade includes a blade feature which interfaces with the interface feature to permit the first rotor blade to be axially mounted within the first of the multiple of blade slots but not within a remainder of the multiple of blade slots. | 02-28-2013 |
20130156584 | COMPRESSOR ROTOR WITH INTERNAL STIFFENING RING OF DISTINCT MATERIAL - A compressor rotor has a hub at a radially outer location, and a leg extending from an inner ring at a radially inner location to the hub. The hub has an inner bore at a location spaced from the leg. A stiffening ring is force fit into the inner bore of the hub. | 06-20-2013 |
20140056713 | TURBINE ENGINE ROTOR ASSEMBLY - A turbine engine rotor assembly includes a turbine engine rotor disk that extends axially along a centerline between a first disk end and a second disk end, and radially to an outer disk surface. The rotor disk includes one or more blade retention slots arranged circumferentially around the centerline. A first of the blade retention slots extends axially into the rotor disk from a disk end surface at the first disk end to a slot end surface, and radially into the rotor disk from the outer disk surface to a slot base surface. | 02-27-2014 |
20140070794 | SENSOR AND TOOTH ARRANGEMENT FOR SHAFT SPEED DETECTION - A non-ferrous shaft includes multiple non-integral ferrous tooth components, thereby allowing a sensor to detect the shaft speed. | 03-13-2014 |
20140133991 | GAS TURBINE ENGINE FAN BLADE LOCK ASSEMBLY - A gas turbine engine fan blade lock assembly includes a fan hub that has blade slots each configured to receive a root of a fan blade. The fan hub includes circumferentially spaced first slots. A lock ring is configured to move between unlocked and locked positions. The lock ring includes circumferentially spaced second slots aligned with the first slots in the locked position, and multiple discrete pins. Each pin is configured to be slidably received in paired first and second slots in the locked position to prevent rotational movement of the lock ring relative the fan hub. | 05-15-2014 |
20140199176 | GAS TURBINE ENGINE NOSE CONE ATTACHMENT CONFIGURATION - A gas turbine engine fan section includes a fan hub configured to rotate about an axis. A nose cone includes a spinner operatively mounted to the fan hub. The spinner supports a first fastening element and the nose cone includes an annular cover arranged over the fastening element. The spinner and annular cover provide an aerodynamic exterior surface of the nose cone without exposed fasteners. A second fastening element cooperates with the first fastening element to secure the spinner relative to the fan hub. The first and second fastening elements are oriented transversely to the axis. | 07-17-2014 |
20140255196 | DOUBLE SPLIT BLADE LOCK RING - A rotor assembly for a gas turbine engine includes a plurality of blades including a root portion and an airfoil portion. The rotor includes a plurality of slots that receive the root portion of a corresponding blade. The rotor includes an annular groove for a first and second retaining ring. The retaining rings are received within a common annular groove for holding each of the plurality of blades within the slots of the rotor. | 09-11-2014 |
