Which term describes the rotor condition when rotor force has been removed or when the rotor is operating under low or negative G?

• A. Unloaded Rotor
• B. Loaded Rotor
• C. Free Rotor
• D. Hovering Rotor

Answer: (A)

Unloaded rotor describes the rotor condition when the rotor is not producing lift to support the aircraft’s weight. This happens when rotor force is removed or the aircraft experiences low or negative G, so the rotor isn’t required to carry load. In this state, the lift demand on the rotor is essentially zero, unlike a loaded rotor which is bearing the weight, or a hovering rotor which is actively lifting to hold a hover. A free rotor, on the other hand, refers to a rotor that is not driven by the engine and free to coast, which is a different situation. So the term that fits the described condition is unloaded rotor.
