🔍 Key Concepts

• Unidirectional propulsion shafting means the shaft only turns in one direction during normal operation • How controllable-pitch propellers (CPP) change thrust direction without reversing shaft rotation • How fixed-pitch propellers and other designs usually change ahead/astern thrust

💭 Think About

• Think about which propeller type can produce both ahead and astern thrust while the shaft continues to rotate in the same direction • Ask yourself: which design relies on changing the blade angle (pitch) instead of changing the shaft rotation? • Consider the typical installation: on which type of vessel or machinery would reversing the main engine’s direction be difficult or undesirable?

✅ Before You Answer

• Verify which option allows reversing thrust without reversing shaft rotation • Check which listed propulsor type typically has blades mounted so that their pitch can be adjusted in service • Eliminate any designs that normally require reversing engine/shaft rotation to get astern thrust
