The first Russian UAV Kor-112 made of plastic polymer. The Novosibirsk company OKB tested the Kor-112 heavy UAV. The Night Bird UAV is created according to the “flying wing” design, which allows the drone with a base weight of 21.5 kilograms to take off from any site or from water, without a catapult, with a take-off run of only 50 meters. The drone was successfully tested in cold weather of 37 degrees. The Kor-112 UAV is controlled by changing the thrust differential of the power plants. The efficiency of this method of taxiing is higher than that of the classic method with a deflectable plane, which allows you to control the drone not only in the air but also on the ground. To maintain flight, the thrust of one engine is sufficient, this allows you to return the drone if one of the drives fails. The drone is made of thermoplastic polymer, which has not been used before; any breakages or holes can be easily repaired on the drone using a soldering iron. The UAV is equipped with a cargo compartment with a hatch in the lower part of the fuselage, which allows it to accommodate any load weighing 13.5 kg, including ammunition. The drone is equipped with Chinese engines, but Russian ones can also be used in large-scale production. The company can produce up to 1,000 drones per month, currently producing 60. In an emergency, the drone returns to the starting point on its own. The estimated flight range of the drone is 30 kilometers, in repeater mode 60 kilometers and above, the drones change frequencies and transmit data to each other. The drone's flight time with an electric motor is 2.5 hours, with additional batteries up to 6 hours, with a gasoline engine 2 hours. The drone's flight altitude is 6 kilometers, speed is 215 km/h. The cargo compartment of the drone is 620 mm long, 160 mm high and 360 mm wide. The wingspan of the drone is 2700 mm, the length of the drone is 1200 mm.
