Abstract: A translational thrust system for a high speed rotary-wing aircraft includes a propeller system driven by a propeller gearbox (42), a hydraulic system (44), and a mechanical-hydraulic control system (48). The mechanical-hydraulic control system utilizes a hydraulic fluid which travels to and from a propeller dome (62) via an oil transfer/position feedback tube (72) which translates with a propeller pitch change piston (68). Translation of the oil transfer/position feedback tube and the propeller pitch change piston pitches the blades (64) between high (coarse) and low (fine) pitch positions.
