GY-500 UAV at MAKS-2021

GY-500, a Russian UAV of the LLC "Research and Engineering Company", is presented at MAKS-2021. An important difference from many initiative projects in the field of small aviation traditionally exhibited at MAKS-2021 is that the GY-500 is already flying and undergoing testing.

The exhibition presents the first flight sample made in the basic cargo configuration, and the construction of the second "agricultural" board is underway.

The GY-500 is a gyrocopter. With this scheme, the lifting force is created by a screw freely rotating under the action of the incoming airflow. Unlike a helicopter, the GY-500 propeller does not spin by the force of the power plant, and therefore there is no need to compensate for the torque with the tail rotor. This greatly simplifies the design of the machine: the main rotor gearbox of a helicopter has a complex mechanism, its failure often becomes the cause of helicopter accidents and catastrophes.

Autogiros cannot take off vertically, they rather do a little take-off run, but can land almost vertically; they cannot hover, but have lower fuel consumption than a helicopter, and are able to fly at extremely low speeds.

One of the potential main applications of this UAV is agriculture, as tasks such as field treatment from the air require high accuracy of flight at ultra-low speeds and altitudes. Additionally, the GY-500 is planned to be used as a cargo UAV (delivery of goods weighing up to 200 kg) and as a civil "intelligence" UAV for various purposes (search and rescue, environmental monitoring, emergency response, etc.).

The possibility of using the GY-500 in combat is also potentially stated, but this requires the placement of a special payload and the interest of customers. So far, the vehicle has been optimized for civilian customers. Interestingly enough, the Rotax 912ULS, using car gasoline, has been chosen as the engine.

In addition to the GY-500, the Research and Engineering Company is presenting an ultralight two-seater Sigma-7 aircraft at the exhibition. The aircraft is designed for individual use, towed behind the car on a small trailer, stored with folded wings in a regular garage. At the moment, the car is undergoing European certification.
