A gyrocopter's rotor isn't powered — it spins in the airflow like a maple seed, generating lift while a pusher prop provides thrust. Invented in 1923, beloved by people who like their aviation slightly eccentric.

Fun fact

A gyrocopter's rotor is turned by the wind alone — the same autorotation that lets helicopters land engine-out.
