By which of the following means is force efficiently provided to vary the pitch of the blades on a modern controllable pitch propeller?

🔍 Key Concepts

• How blade pitch on a controllable pitch propeller (CPP) is changed during operation • Which power-transmission method is best for providing smooth, strong, reversible linear motion inside a rotating propeller hub • Practical considerations on ships: reliability, space, sealing, and response time in the propeller shaft line

💭 Think About

• Think about which system can easily apply a large, steady force along the propeller shaft to move a piston or mechanism that turns the blades in the hub • Consider which option is most commonly used in heavy marine machinery to transmit force over short distances with fine control • Ask yourself which method can be safely contained and sealed inside a rotating hub that is underwater and still be controlled from the engine room or bridge

✅ Before You Answer

• Identify which option is most widely used in modern shipboard machinery actuators (steering gear, stabilizers, CPP, etc.) • Eliminate any option that would be difficult to seal inside a submerged, rotating hub • Consider which method provides high force with compact equipment and precise, smooth control of blade angle
