UAV for Arctic conditions developed in Russia

31 january 2024

The Novosibirsk OKB design bureau has developed an aircraft-type unmanned aerial vehicle (UAV), made from low-temperature polymers that have not previously been used in aviation. It is capable of operating at temperatures of minus 60 degrees, TASS quotes the general director of the bureau Konstantin Koryukin as saying.

The UAV can be used to monitor gas pipelines, and in the future, to deliver goods to the Arctic.

“It has to be an all-weather [vehicle]. We used materials such as low-temperature polymers, which had not previously been used in aviation. It can work safely at temperatures of minus 60 degrees. We tested it in the cold, and not only the materials, but also the components are in order. This drone is extraordinary; it can take off from unprepared sites without a special launch complex,” Koryukin noted.

Currently, a pre-production prototype has been developed, production launch is planned for late February - early March.
