Which component produces thrust to move the airplane, described as a rotating wing with a thick leading edge?

• A. Jet Engine
• B. Aircraft Propeller
• C. Ram Air Turbine
• D. Helicopter Rotor

Answer: (B)

Thrust for a fixed‑wing airplane comes from a propulsive device that pushes air backward. An aircraft propeller is basically a set of rotating airfoils. As the blades spin, each blade has a pitch that causes the air to be deflected rearward. This deflection produces a forward reaction force on the blade, which is transmitted to the fuselage as thrust, pushing the airplane ahead. The blade’s thick leading edge helps it withstand the structural loads near the hub and maintains good pressure distribution so the blade can generate lift over a range of angles of attack as it rotates. Jet engines produce thrust by accelerating exhaust gases out the back, not by acting as rotating wings. A ram air turbine is a small, emergency power device, not the primary propulsion. A helicopter rotor is also a rotating wing, but it powers vertical flight for rotorcraft and is not the typical propulsion method for a conventional fixed‑wing airplane.
