HYDRODYNAMIC DESIGN CONSIDERATIONS FOR THE CONTROLLABLE PITCH PROPELLER FOR THE GUIDED MISSLE FRIGATE

The restrictions imposed on a propeller design by the controllable-pitch feature can be severe. In the case of the Guided Missile Frigate (FFG), the constraints were a controllable-pitch propeller absorbing 40,000 shaft horsepower (SHP), with distinct mission performance requirements related to propeller efficiency and cavitation performance. The hydrodynamic design of the FFG propeller involved "trade-offs" between full-power and design- endurance speed and considerations of blade strength, vibration, cavitation characteristics, and propeller blade spindle torque. Model experiments confirmed that considering the constraints imposed on the design, use of the best available design procedures and analytical techniques has resulted in a propeller for the FFG which has good overall performance.
