Title:
METHOD AND SYSTEM FOR INTEGRATED PITCH CONTROL MECHANISM ACTUATOR HYDRAULIC FLUID TRANSFER
Document Type and Number:
Japanese Patent JP2017160902
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a variable pitch propeller assembly with a plurality of propeller blade assemblies spaced circumferentially about a hub.SOLUTION: Each of the plurality of propeller blade assemblies is configured to rotate a corresponding propeller blade. The variable pitch propeller assembly also includes a hydraulic fluid port assembly integrally formed and including at least three hydraulic fluid ports configured to receive respective flows of hydraulic fluid from a stationary hydraulic fluid transfer sleeve. The variable pitch propeller assembly also includes a pitch actuator assembly coupled in flow communication with the at least three hydraulic fluid ports through respective hydraulic fluid transfer tubes. The pitch actuator is coupled to the plurality of propeller blade assemblies so as to selectively control a pitch of the propeller blades. The pitch actuator assembly includes a travel stop configured to limit a rotation of at least one of the pitch actuator assemblies.SELECTED DRAWING: Figure 1
