🔍 Key Concepts

• Controllable-pitch propeller (CPP) basic layout: hub, blades, links, and actuating mechanism • What part actually MOVES inside the hub to transmit force to the blade roots? • Difference between an internal actuating piston/rod and external control parts like crossheads or crank pins

💭 Think About

• Picture a cutaway of a CPP hub: when oil pressure changes, which internal item slides forward or aft to make the blades twist? • Which component is directly connected to the links or cranks that turn each blade about its own axis? • Of the four choices, which one is normally the main axially‑moving actuator inside the hub rather than a follower or external linkage part?

✅ Before You Answer

• Identify which part in typical CPP diagrams is shown moving axially (along the shaft centerline), not rotating. • Check which component is commonly located inside the hub body, surrounded by oil, and driven by hydraulic pressure. • Eliminate any parts that normally act as linkages or followers rather than the primary hydraulic actuator.
