How does a gyroplane generate lift?
- A.Through fixed wings, like a conventional aeroplane
- B.Through an engine-driven rotor, like a helicopter
- C.Through a freely rotating rotor system
- D.Through a lighter-than-air gas envelope
Correct answer
Explanation
The correct answer is through a freely rotating rotor system. This is the defining characteristic of the gyroplane: the rotor above the aircraft is not driven by the engine but turns freely in the airflow, and that rotation produces the lift, while the forward thrust is supplied separately by a propeller. Option A describes a conventional fixed wing aeroplane, in which lift comes from the wings as the aircraft moves forward, which is a different arrangement. Option B describes a helicopter, whose rotor is powered by the engine, and it is precisely this distinction that separates the helicopter from the gyroplane. Option D describes an airship or a balloon, which stays aloft because the gas inside it is lighter than the surrounding air and which has no rotor at all. So option C is the only accurate description.
