Gyrocopter autogyro

The gyrocopter, also known as an autogyro, is a rotorcraft that uses autorotation to generate lift.

About this subject

The gyrocopter, also called autogyro, is a rotorcraft that combines features of helicopters and airplanes. Unlike a helicopter, its main rotor is not powered during flight; it spins freely via autorotation, driven by the upward airflow. Propulsion is provided by a conventional propeller mounted on the rear or front of the fuselage.

Invented by Spanish engineer Juan de la Cierva in 1923, the autogyro was the first practical and successful rotorcraft. The first flight took place on January 9, 1923, at the Cuatro Vientos Aerodrome in Madrid. De Cierva aimed to create a safe aircraft that would not stall like fixed-wing planes. His invention, the articulated rotor, solved the asymmetric lift problem by allowing blades to change their pitch angle.

Autogyros are known for their inherent safety: even with engine failure, they can glide and land safely because the rotor continues spinning. They are used for recreational flying, aerial mapping, precision agriculture, and surveillance. Some military models were developed, such as the Focke-Achgelis Fa 330, used by German submarines in World War II as an aerial observation platform.

Today, gyrocopters are popular among sport aviation enthusiasts. Companies like AutoGyro GmbH in Germany and Magni Gyro in Italy produce modern models, many with enclosed cockpits and efficient engines. Flying a gyrocopter requires less landing space than a conventional airplane and offers a unique experience of low-speed, moderate-altitude flight.

Frequently Asked Questions

What is the difference between a gyrocopter and a helicopter?

In a helicopter, the main rotor is powered and can generate lift even when stationary (hovering). In a gyrocopter, the rotor spins freely via autorotation and the aircraft must be in motion to generate lift. Gyrocopters cannot hover.

Is it difficult to fly a gyrocopter?

Flying a gyrocopter is considered simpler than flying a helicopter, but requires specific training. The pilot controls direction and altitude with controls similar to an airplane, while the rotor acts as a rotating wing.

Where can I see or fly in a gyrocopter in Brazil?

In Brazil, there are aviation clubs and schools offering demonstration flights and courses, mainly in regions such as São Paulo, Rio de Janeiro, and Minas Gerais. ANAC regulates these aircraft as experimental or sport aircraft.
