The pilot flies the autogyro over the countryside.

Definition

1. Noun:
   • An aircraft that is supported in flight by unpowered rotating horizontal wings (or blades); forward propulsion is provided by a conventional propeller: An autogyro is a type of rotorcraft that uses an unpowered rotor to generate lift. The rotor spins freely due to aerodynamic forces as the aircraft moves forward, which is powered by a separate, conventional engine-driven propeller.

Usage Examples

• Noun:
  • The early aviation pioneer developed a successful autogyro in the 1920s.
  • Unlike a helicopter, the rotor of an autogyro is not powered by an engine during flight.

Advanced Usage

• Technical Context: In technical and historical discussions of aviation, "autogyro" specifically denotes the class of aircraft where the rotor auto-rotates to provide lift, distinguishing it from helicopters.
  • The principle of autorotation, essential for autogyro flight, is also a safety feature in helicopters.

Variants and Related Words

• Autogiro (n): An alternative spelling for "autogyro." Both terms refer to the same type of aircraft.
  • The term "autogiro" was a trademark that became a generic name for the aircraft.
• Gyroplane (n): Another term often used synonymously with autogyro.
  • Modern regulations may classify these aircraft as gyroplanes.
• Rotorcraft (n): A broader category of aircraft that use lift-generating rotors, which includes both autogyros and helicopters.
  • Helicopters and autogyros are both types of rotorcraft.

Synonyms

• Gyrocopter: A common term, especially for modern, light autogyros.
• Rotor kite: A term sometimes used, particularly for early or simple designs.

Related Phrases

• In autorotation: The state of the rotor spinning due to aerodynamic forces rather than engine power, which is the fundamental operating principle of an autogyro.
  • The rotor must be in autorotation for stable autogyro flight.
