| 20080260522 | GAS TURBINE ENGINE WITH INTEGRATED ABRADABLE SEAL AND MOUNT PLATE - An abradable sealing land for a gas turbine engine includes a mount plate and an open cell portion which is to be abraded. Both portions are formed integrally from a single piece of material. | 10-23-2008 |
| 20080260523 | GAS TURBINE ENGINE WITH INTEGRATED ABRADABLE SEAL - An abradable land assembly for a gas turbine engine includes a mount portion and an open cell portion which is to be abraded. Both portions are formed integrally from a single piece of material. | 10-23-2008 |
| 20090051120 | Gas Turbine Engine Systems Involving Hydrostatic Face Seals - Gas turbine engine systems involving hydrostatic face seals are provided. In this regard, representative turbine assembly for a gas turbine engine includes a turbine having a hydrostatic seal formed by a seal face and a seal runner. | 02-26-2009 |
| 20090148271 | Bearing mounting system in a low pressure turbine - A bearing mounting system for use in a gas turbine engine having a low pressure turbine supported on a low pressure shaft through a support rotor comprises a low pressure turbine case, a forward bearing and an aft bearing, and a forward support structure and an aft support structure. The low pressure turbine case surrounds the low pressure turbine. The forward bearing and the aft bearing are positioned on the low pressure shaft to straddle the support rotor. The forward support structure and the aft support structure connect the forward bearing and the aft bearing, respectively, to the low pressure turbine case. The low pressure shaft extends axially between the forward bearing and the aft bearing. In one embodiment, the turbine comprises a plurality of adjacent rotor disks, and the support rotor comprises a conical support connecting one of the rotor disks with the shaft. | 06-11-2009 |
| 20090238683 | Vane with integral inner air seal - A stator vane segment for a gas turbine engine includes at least one airfoil joined to an outer shroud and an inner platform. A sealing element having a first platform radially inward of the inner platform and an abradable material covering at least a portion of the first platform is integrally joined to the inner platform. | 09-24-2009 |
| 20090257877 | ASYMMETRICAL ROTOR BLADE FIR-TREE ATTACHMENT - A rotor blade for a gas turbine engine includes an asymmetric attachment section received within a rotor disk rim with an asymmetric slot. | 10-15-2009 |
| 20110206522 | ROTATING AIRFOIL FABRICATION UTILIZING CMC - Disclosed is an airfoil comprising a plurality of ceramic matrix composite (CMC) fabric sheets which are layered to form a single, layered fabric sheet. The layered fabric sheet is formed so as to define a pressure and suction side of the airfoil. The airfoil includes primary fibers which extend radially outwardly from a rotor disk, for example. In this way, the airfoil is suitable for use in a gas turbine engine due to the temperature resistance of CMC and the strength provided by the primary fibers. | 08-25-2011 |
