Question

Which aeronautical term is an aircraft that derives its lift from rotating lifting surfaces?

Answer 1

The term is Rotorcraft.

Step-by-step explanation:

A Rotorcraft is a flying vehicle that lifts from the ground using mainly airfoils.

A helicopter is a common example. They usually include, and almost entirely rely on their rotors to lift and maintain flight, pushing air down so that a reaction occurs to push the aircraft upwards. Besides helicopters, there are other types such as the autogyro, which instead of pushing air down using an engine rotor, uses an engine to move forward, and a non-powered rotor to lift from the ground, which pushes the air upwards instead.

As an interesting fact, the first fully operational helicopter made was the Focke-Wulf Fw 61, in 1936, created by Henrich Focke and Gerd Achgelis.

Answer 2

The answer is rotorcraft.

A rotorcraft uses lift generated by wings that revolve or rotates around a mast. Generally, rotorcraft includes aircraft such as helicopters, gyrodynes, cyclocopters, and autogyros that use one or more rotors to provide lift throughout the entire flight. For instance, on a helicopter, there is a left or right movement of cyclic which will command a roll motion from the rotor.
