  • Seals for rotor system fairings
    Patent number: 10899438
    Abstract: A fairing system, includes a hub fairing and a fixed fairing, such as a shaft fairing or a pylon fairing, both arranged about a rotation axis. A gap is defined between the hub fairing and the fixed fairing, and a seal assembly is axially interposed between the hub fairing and the fixed fairing. The fixed fairing and the hub fairing are both removably mounted to the seal assembly such that either or both of the fairings can be dismounted from the seal assembly without disturbing the seal assembly to provide access to components disposed within the fairing.
    Type: Grant

  • In-wing device retention
    Patent number: 9914533
    Abstract: A method of forming an in-wing device-retention assembly includes inserting a first plate into a wing, the wing having a wide end and a narrow end. The method includes inserting a second plate into the wing, inserting a wedge plate into the wing and positioning the wedge plate between the first plate and the second plate, and applying a force to the wedge plate in a direction toward the narrow end to fix the first plate, the second plate and the wedge plate within the wing.

  • SYSTEMS AND METHODS FOR DAMPING ROTOR BLADE ASSEMBLIES
    Publication number: 20170036758
    Abstract: A rotor blade assembly includes a blade body having a leading edge and a trailing edge. A damper element is disposed within the blade body and along a forcing axis extending between the leading and trailing edges of the blade body to apply damping force in-plane with the blade body to damp load and oppose edgewise motion of the blade body associated with the load.
