Autogyro drone in flight

ThunderFly

Unmanned aerial vehicles designed for adverse weather conditions

ThunderFly is a Czech company specializing in the development and production of unmanned aerial vehicles designed to operate in unfavorable weather conditions. Our flagship product is a modifiable open-source autogyro carrier with excellent stability in any weather. This can prove especially useful for researchers and rescue teams, though the autogyro’s modular design allows for nearly universal use across a wide range of applications.

The Autogyro – A Universal Aircraft

Emergency unpowered autorotation mode

System design emphasizes safety and easy maintenance

Electric drive ensures reliable operation

Redundant control surfaces

The autogyro is a type of rotorcraft similar to a helicopter. Unlike a helicopter, an autogyro’s rotor is unpowered. Instead, an autogyro is provided with an engine-driven propeller. It is the forward thrust of the propeller with its accompanying airflow that spins up the main rotor, which in turn generates lift. This arrangement significantly simplifies the construction of the rotor and lowers the demands for maintenance.

The autogyro combines the benefits of an airplane and a helicopter. It is capable of very slow flight while preserving high maneuverability. However, it cannot hover in the air.
