Serial deliveries are planned to begin in 2024
MOSCOW, October 10. /TASS/. The flat nozzle of the S-70 Hunter drone, grown on a 3D printer, will reduce its visibility for missiles. This was announced on Sunday on the TV channel "Zvezda" by the deputy general designer of the OKB "Motor" of PJSC "UEC UMPO" Sergey Kuzmin.
"We effectively disperse it [the jet stream from the nozzle] and most importantly, with constructive measures in the inner part of the nozzle, we cover the hot parts of the engine with cold elements. The rocket will not see the hot blades of the engine," Kuzmin said.
In addition, according to him, most of the nozzle is hidden under the fuselage of the aircraft, which also reduces visibility for missiles.
"The nozzle is made using additive technologies [3D printing], which allows us to significantly reduce the time and money for manufacturing and pre-production," the deputy general designer stressed.
According to him, the second version of the Hunter will have an engine with a new, flat nozzle. "There is no such nozzle on any Russian fighter now. But this is a global trend, at the end of the XX century, all combat fighters are made with flat nozzles," he stressed.
The S-70 drone developed at the Sukhoi Design Bureau is made according to the "flying wing" scheme using stealth technology, which reduces its radar visibility. According to open sources, the take-off weight of the device is up to 20 tons, the maximum flight speed is about 1,000 km / h. Serial deliveries are scheduled to begin in 2024. The Hunter took to the air for the first time on August 3, 2019.
