  • Patent number: 10801327
    Abstract: A turbine blade for a gas turbine engine is disclosed. The turbine blade includes an airfoil including leading and trailing edges joined by spaced-apart pressure and suction sides to provide an exterior airfoil surface extending from a platform in a radial direction to a tip. The external airfoil surface is formed in substantial conformance with multiple cross-sectional profiles of the airfoil described by a set of Cartesian coordinates set forth in Table 1, the Cartesian coordinates provided by an axial coordinate scaled by a local axial chord, a circumferential coordinate scaled by a local axial chord, and a span location, wherein the local axial chord corresponds to a width of the airfoil between the leading and trailing edges at the span location.
    Type: Grant

  • Patent number: 6006356
    Abstract: A garment having an elongated body of sheet material having a length at least equal to the length of a wearer's upper torso, and a width at least twice the width of said torso, the garment body including three arm receiving openings arranged longitudinally thereon, said openings including a center opening approximately on the transverse center at substantially a midpoint of the width of the garment body, and two side openings each to one side of the center opening, said three openings being separated by a distance approximately equal to the width of said torso.
