摘要： 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).

摘要： The hydraulic propeller system of the present invention has a central hub (14) including a stationary portion (28), and a rotatable portion (30). A plurality of propeller blades (12) are connected with the rotatable portion (30), wherein each of the plurality of propeller blades (12) has an adjustable pitch, and a counterweight (26) biasing the blades (12) in a first pitch direction . An actuating mechanism (16) is used for adjusting the pitch of each of the plurality of blades (12). A valve (56) for locking the propeller blades (12) at a last commanded pitch is further provided. At least the valve (56), the actuating mechanism (16) are located on, and rotatable with, the rotatable portion (30).
