    Abstract: A system (10) for controlling propeller blade pitch is disclosed. The system (10) comprises a transfer tube (18), wherein the transfer tube (18) defines an element of the rotatable portion (12) and wherein the transfer tube (18) is non-translating relative the rotatable (12) and non-rotatable portions (26). A transfer bearing (16) for providing hydraulic fluid to and interfacing with the transfer tube (18) is also used, wherein the transfer bearing (16) is located on the non-rotatable portion (26). The system further includes a pitch change actuator (22) and a mechanism form (74) for actuating the pitch change actuator (22), wherein the mechanism (74) is fluidically connected to and translatable relative to the transfer tube (18). A device for measuring blade angle of the propeller blade (120) is also provided, wherein the device is separate and distinct from the transfer tube (18).

    Abstract: A pressure relief device for preventing over pressurization of a propeller hub is disclosed. The pressure relief devices is designed to fit within a ball hole opening in the hub arm of the hub. The pressure relief device includes a housing which sealably interfaces with an inner wall of the ball hole opening and a pressure relief insert which sealably interfaces with the housing. The pressure relief device includes a plurality of fracture tabs which engage an end of the housing exposed to hub cavity pressure. The fracture tabs are designed to break at a design pressure allowing the pressure relief insert to be forced out of the housing thus breaking the seal between the pressure relief insert and housing thereby venting the hub cavity.
