20170167264 | TURBINE ROTOR FOR A GAS TURBINE ENGINE - A turbine rotor for a gas turbine engine, includes an upstream turbine disk; a downstream turbine disk; an annular flange; a first ferrule connecting the upstream turbine disk to the annular flange; a second ferrule connecting the downstream turbine disk to the annular flange; an air flow separator device including: a first part, forming a first ring, arranged between the upstream turbine disk and the downstream turbine disk; a second part, forming a second ring, having a first portion facing the downstream turbine disk, and a second portion arranged between the first ferrule and the second ferrule; and a thermal insulation area arranged between the first part and the second part. | 2017-06-15 |
20170167265 | STEAM TURBINE, BUCKET, AND METHOD OF MAKING BUCKET - A bucket includes a bucket body including a precipitation hardened martensitic stainless steel having a tensile strength of at least 1520 MPa (220 KSI) and a notch toughness of at least 41 J (30 ft-lb). The bucket body has a radial length of at least 1.15 meters (45 inches). A steam turbine includes at least one bucket including a precipitation hardened martensitic stainless steel having a tensile strength of at least 1520 MPa (220 KSI) and a notch toughness of at least 41 J (30 ft-lb). The bucket has a radial length of at least 1.15 meters (45 inches). A method of making a bucket having a radial length of at least 1.15 meters (45 inches) includes forming a precipitation hardened martensitic stainless steel having a tensile strength of at least 1520 MPa (220 KSI) and a notch toughness of at least 41 J (30 ft-lb) into the bucket. | 2017-06-15 |
20170167266 | GAS TURBINE ENGINE AIRFOIL - An airfoil of a turbine engine includes pressure and suction sides and extends in a radial direction from a 0% span position to a 100% span position. The airfoil has a relationship between a stagger angle and span position that defines a curve with a stagger angle that is greater than 32° from 90% span to 100% span. | 2017-06-15 |
