🔍 Key Concepts

• Z-drive configuration and how it changes thrust direction • Difference between azimuthing propulsion and specific brand names/designs • How cycloidal propellers and jet drives work compared to Z-drives

💭 Think About

• Think about what the term 'Z-drive' describes about the shape or movement of the power transmission and thrust direction. • Ask yourself: does a Z-drive rotate to point thrust in any horizontal direction, or does it work in a completely different way like a waterjet or cycloidal unit? • Consider whether 'Azipod' is a general technical term or a specific trade name for a particular manufacturer's design.

✅ Before You Answer

• Verify which option describes a generic type of propulsion rather than a specific brand or a totally different system. • Check which choice allows the propeller/drive to rotate 360° in azimuth to direct thrust. • Confirm that a cycloidal propeller and a jet drive operate on distinctly different principles from a Z-drive.
