🔍 Key Concepts

• Slow-speed crosshead diesel engines and how they are typically connected to the propeller shaft • Difference between fixed-pitch propeller (FPP) and controllable-pitch propeller (CPP) and how each reverses thrust • How engine reversing differs from pitch changing as methods of obtaining astern thrust

💭 Think About

• Ask yourself: On big slow-speed crosshead main engines driving a single screw, is it more common to change the direction of engine rotation, or to change propeller blade pitch to get astern thrust? • Consider whether a controllable-pitch propeller is usually paired with slow-speed crosshead main engines, or more often with medium‑speed engines through reduction gears. • Think about which combinations are mechanically sensible: Can a non‑reversing engine work with a fixed‑pitch propeller for astern power without some other device?

✅ Before You Answer

• Verify which type of propeller (fixed-pitch vs controllable-pitch) is most commonly used directly on the shaft of a slow-speed crosshead diesel. • Check whether a non-reversing engine can directly drive a fixed-pitch propeller and still provide astern thrust without additional reversing gear. • Confirm whether slow-speed crosshead engines are normally reversible engines (able to start and run in either ahead or astern rotation).
