rotorcraft
C1/C2Technical, formal
Definition
Meaning
An aircraft that generates lift through one or more powered rotors.
A category of aircraft including helicopters, gyroplanes, and similar vehicles that rely on rotating wings (rotors) for lift and propulsion, as opposed to fixed-wing aircraft.
Linguistics
Semantic Notes
Primarily used in aviation contexts; often synonymous with 'rotary-wing aircraft'. Distinguish from 'fixed-wing aircraft' and 'VTOL' (Vertical Take-Off and Landing), which is a capability, not a vehicle type.

Frequently Asked Questions
No. 'Helicopter' is a specific type of rotorcraft. 'Rotorcraft' is the broader category that also includes autogyros, gyrodynes, and convertiplanes like tiltrotors.
Primarily in formal, technical, and regulatory contexts such as aviation authority publications (FAA, EASA), engineering textbooks, military procurement documents, and aerospace industry reports.
Their ability to perform Vertical Take-Off and Landing (VTOL) and to hover, which allows operations in confined spaces without the need for runways.
Yes, multirotor drones (quadcopters, etc.) are a type of rotorcraft, often specifically referred to as 'unmanned rotorcraft' or 'UAS' (Unmanned Aircraft Systems).
