  • Helicopter tail rotor blades and blade assemblies
    Patent number: 10906638
    Abstract: A tail rotor blade for a helicopter includes a blade body defining a longitudinally extending spar cavity, a leading edge forward of the spar cavity, and a trailing edge aft of the spar cavity. Upper and lower airfoil surfaces extend from the leading edge to the trailing edge on opposite sides of the spar cavity. The upper and lower airfoil surfaces define between one another a constant airfoil segment and transition airfoil segments disposed longitudinally adjacent to the constant airfoil segment on inboard and outboard sides of the constant airfoil segment.
    Type: Grant
    Filed: January 25, 2017
    Date of Patent: February 2, 2021
    Assignee: SIKORSKY AIRCRAFT CORPORATION
    Inventors: Krzysztof Kopanski, Daniel A. Griffiths, Joshua A. Breon, Jonathan K. Wong, Benjamin Isabella, Michael Skylar Lawson
  • Estimation of gross weight and center-of-gravity
    Patent number: 10267669
    Abstract: Embodiments are directed to obtaining data from at least one sensor, the data pertaining to rotor loads and motion, processing, by a device comprising a processor, the data to obtain an estimate of at least one of gross weight (GW) and center of gravity (CG) for a rotorcraft, and outputting the estimate.
