Gyrocopter autogyro

The autogyro, a precursor to the modern helicopter, combines free-spinning rotor autorotation with a rear propeller for lift and thrust.

About this subject

The autogyro, also known as a gyrocopter, is a rotary-wing aircraft whose main rotor is not powered by an engine but spins freely due to upward airflow during flight. This condition, called autorotation, allows the autogyro to fly safely at low speeds and land near-vertically. Unlike a helicopter, which uses an engine to drive the rotor, the autogyro requires a conventional rear propeller to generate forward thrust. Invented by Spanish engineer Juan de la Cierva in 1923, the autogyro was the first flying vehicle to use rotors for lift, directly influencing the development of helicopters. In the 1930s, models like the Cierva C.30 were used for military reconnaissance and training. Today, the autogyro is popular among sport aviation enthusiasts, especially models such as the RAF 2000 and the Magni M16. In Brazil, there is an active community of autogyro pilots, with an emphasis on safety and low operating costs. The aircraft is known for its stability and stall resistance, making it a safe option for leisure and aerial monitoring. Interestingly, the term "gyrocopter" is a common English variant, while "autogyro" is the traditional name.

Frequently Asked Questions

What is the difference between an autogyro and a helicopter?

An autogyro has an unpowered rotor that spins by autorotation, while a helicopter uses an engine to drive the rotor. Autogyros cannot hover like helicopters but are simpler and cheaper to operate.

Who invented the autogyro?

It was invented by Spanish engineer Juan de la Cierva in 1923, with the first successful flight in 1923 in Spain.

Is the autogyro safe?

Yes, it is considered very safe due to autorotation, which maintains lift even if the engine fails. Additionally, it cannot stall because the rotor always generates lift.
