gyroplane
Noun: An aircraft that achieves lift primarily through unpowered, rotating horizontal wings (or rotor blades). Its forward motion and propulsion are provided by a separate, conventional engine-driven propeller, not by the rotor system itself. This distinguishes it from a helicopter, where the main rotor is powered to provide both lift and thrust.
The term "gyroplane" refers specifically to the type of aircraft. It is a technical term used in aviation. * The gyroplane took off after a short ground roll, its rotor spinning freely in the airflow. * He prefers flying a gyroplane because of its mechanical simplicity compared to a helicopter. * The design of a gyroplane makes it inherently stable in flight.
- Technical Context: In aviation regulations and engineering, "gyroplane" is the formal term for this aircraft category, as defined by bodies like the FAA (Federal Aviation Administration) and EASA (European Union Aviation Safety Agency).
- Historical Context: Early autogyros, a type of gyroplane invented by Juan de la Cierva, were significant in the development of rotary-wing flight.
- Autogyro (noun): A common synonym for "gyroplane." The terms are often used interchangeably, though "autogyro" is sometimes associated with earlier historical designs.
- Gyrocopter (noun): A brand name (Bensen Gyrocopter) that became a generic term for small, open-cockpit gyroplanes. It is often used colloquially.
- Rotorcraft (noun): A broader category of aircraft that use lift-generating rotors, which includes both gyroplanes (unpowered rotor) and helicopters (powered rotor).
- Autogyro
- Rotorcraft (in the specific sense of an unpowered-rotor aircraft)
The word "gyroplane" has a single, specific meaning in aviation. It should not be confused with: * Helicopter: An aircraft whose lift and thrust are derived from one or more powered rotors. * Airplane/Aeroplane: A fixed-wing aircraft that is propelled forward by thrust from a jet engine or propeller.
