Pitch control assembly and propeller blade assembly having a spider hub are disclosed. The spider hub includes a hub and a set of arms spaced circumferentially about the hub and projecting radially from the hub, wherein the set of arms are configured to receive a set of blades such that a blade root of a blade is rotationally mountable into an arm included in the set of arms, a crosshead located within the hub and axially moveable relative to the hub, a torque tube located in the arm and extending into the hub, wherein a pitch angle of the blade can be adjusted by axially moving the crosshead to rotate the torque tube to effect a corresponding rotation of the blade.

Pitch control assembly and propeller assembly and method of adjusting pitch

Hub assembly and propeller blade assemblies incorporating partial hub assembly having a backing plate with a set of partial root seats and a set of clamps selectively operably couplable to the backing plate with each clamp defining a second partial root seat and wherein when a clamp is coupled to the backing plate a root seat is formed, propeller blades having roots are received within the root seats.

Hub assembly and propeller assemblies

Propeller blade assemblies and a propeller blade retention assembly including a sleeve for operably coupling a propeller blade to a hub wherein the sleeve retains the propeller blade within the hub and allows the propeller blade to rotate about its pitch axis and where the sleeve includes a self-aligning mechanism.
