Abstract: Four-bar flapping rotors for aircraft and associated methods are disclosed. An example a flapping rotor hub described herein includes a rotor hub having a first end and a second end, the first end opposite the second end along an axis of rotation of the rotor hub, a first link rotatably coupled to the rotor hub at the first end, the first link to rotate in a plane parallel to the axis of rotation, a second link rotatably coupled to the rotor hub at the second end, the second link to rotate in the plane, and a pitch housing rotatably coupled to the first link at a third end of the pitch housing, the pitch housing rotatably coupled to the second link at a fourth end of the pitch housing, the pitch housing to rotate and translate in the plane, the pitch housing to receive a rotor blade.

Abstract: A fluid handling system comprising an annular sealing device and a flow control system to divert fluid flow from an annulus of a riser package to a control system located on a rig. A method of installing a fluid handling system on a riser package from a rig comprises connecting the fluid handling system to an upper end of a riser string, supporting the fluid handling system and the riser string using a first tubular handling device, and lowering the fluid handling system and the riser string to an operating position.
