  • High-authority yaw control for a tandem vehicle with rigid rotors
    Patent number: 10564648
    Abstract: A method for executing yaw control of an aircraft including two rotors is provided. The method includes inducing helicopter yaw by creating a differential torque between the two rotors, wherein the creating of the differential torque comprises inducing a differential collective pitch to generate a differential thrust, and maintaining helicopter roll equilibrium during the inducing of the helicopter yaw by inducing a differential cyclic pitch to generate a differential lift offset.
    Type: Grant

  • Flexbeam hinge for helicopter blade active trailing edge flap
    Patent number: 9428268
    Abstract: A flexbeam for a rotor blade is provided and includes a first end coupled to a body of the rotor blade and a second end coupled to a flap disposed along a trailing edge of the body to pitch about a pitching axis defined along a span of the body and a flexbeam body extending from the first end to the second end and being configured to retain the flap under a first loading and being flexible about the pitching axis.

  • Multi-element rotor blade
    Patent number: 9211950
    Abstract: A main rotor assembly for a rotary wing aircraft includes a blade assembly secured to a rotor hub. The blade assembly includes a rotor blade and a slat positioned to define a slat gap between the rotor blade and the slat. One or more struts extend from the rotor blade to the slat to position the slat and control motion of the slat. The rotor blade and the slat are secured to a common rotor cuff such that the rotor cuff acts as a centrifugal force support.
