  • Conformal heat shield for gas turbine engine
    Patent number: 10704416
    Abstract: A conformal heat shield for a gas turbine engine may comprise a first section including a first arcuate segment and a second arcuate segment circumferentially adjacent to the first arcuate segment. The first arcuate segment and the second arcuate segment may each comprise a distal metal layer including a plurality of loops extending radially outward from the distal metal layer. A proximal metal layer may be located radially inward of the distal metal layer. An insulating material may be located between the distal metal layer and the proximal metal layer. A first strap may be located through the loops.
    Type: Grant
    Filed: July 13, 2018
    Date of Patent: July 7, 2020

  • STATIC GUIDE VANE WITH INTERNAL HOLLOW CHANNELS
    Publication number: 20150252679
    Abstract: A static guide vane for use in a fan section of a gas turbine engine includes an outer platform and an inner platform. The inner and outer platforms are connected by an airfoil. The airfoil have channels extending into a main body of the airfoil to reduce the weight of the vane. A cover closes off the channels with the cover providing a portion of the airfoil.

  • Structural stator airfoil
    Patent number: 8998575
    Abstract: An airfoil comprises a leading edge, a trailing edge, and pressure and suction surfaces defined therebetween. An inner platform is coupled to a root section of the airfoil, with a curvilinear gusset extending along a lower surface of the inner platform, opposite the root section. An outer platform is coupled to a tip section of the airfoil, with a multi-lobed gusset extending along an upper surface of the inner platform, opposite the tip section.
