Russia develops world’s first light drone with hybrid engine

Russia’s ZALA 421-16E5G aircraft

MOSCOW, April 15. /TASS/: Russia’s ZALA Aero (part of the Kalashnikov Group within the state tech corporation Rostec) has developed the world’s first light unmanned aircraft ZALA 421-16E5G outfitted with a hybrid powerplant combining an electric motor and an internal combustion engine, ZALA Aero Special Projects Head Nikita Khamitov told TASS during the drone’s presentation on Thursday.

"We have been the first in the world to combine an internal combustion engine and an electric motor in this class of drones. The company has made a sequential hybrid: during the flight the internal combustion engine is not the main driving force but feeds the generator and the buffer battery. This, in turn, supplies power to all onboard systems and assemblies, including the electric motor," Khamitov said.

The hybrid powerplant boosts the drone’s flight duration compared to similar unmanned aerial vehicles, he said.

"Thanks to this scheme, we have achieved a flight time of over 16 hours and have provided a possibility to operate over an object of interest in a completely silent mode," Khamitov noted.

The drone’s serial production has already begun, he said. "A customer is already available. The serial production has already been launched," he added.

The ZALA Aero production capacities allow producing up to 300 various drones a year, he added.

The ZALA 421-16E5G is the world’s first unmanned aircraft without an airfield base outfitted with a hybrid powerplant of an electric motor and an internal combustion engine. The drone is positioned as an unmanned reconnaissance aircraft.

"The payload allows using target acquisition, communications relay and 2G, 3G and 4G mobile network monitoring systems. It can conduct radio-technical reconnaissance in the area and identify mobile phones and their location and also relay communications to several dozen kilometers," Khamitov added.
