Frequency tests of a prototype of a promising Russian UAV “Okhotnik” were carried out at the Novosibirsk Aviation Plant. V. P. Chkalov. This was announced today, May 23, in the press service of the Siberian Research Institute of Aviation (SibNIA) named after. S. A. Chaplygin. (part of the Federal State Budgetary Institution “Research Center” Institute named after N. E. Zhukovsky “).

“In May of the year, in the branch of JSC “Company” Sukhoi “NAZ them. V. P. Chkalov, frequency experimental tests of the promising Russian unmanned aerial vehicle Okhotnik were carried out using an elastic suspension system developed at SibNIA, ”the institute noted.

There it is explained that frequency measurements end with a developmental stage and exceptional cases of dangerous aeroelastic resonant vibrations and obtaining experimental data on the evaluation of all elements of the airframe structure in order to predict the behavior of the aircraft in the event of flat feet. A prototype is subjected to testing, which is carried out with an inspection of all regular on-board systems and assemblies.

As provided in the press service, a system of elastic hanging of packages for unloading aircraft during frequency requests with an imitation of the state of horizontal flight. The installed system is not significant for measuring coverage characteristics during testing, and its dimensions do not interfere with retraction, extension of the housing and movement of deviations.

“The created size of an insignificant small-sized system allows testing any type of representatives of the Sukhoi company,” SibNIA added.

We remind you that the S-70 Okhotnik, discovered in the design bureau of the Sukhoi UAV, performed a “flying wing” scheme using stealth technology, which showed its radar observability. According to the received data, the takeoff weight of the device is up to 20 tons, the maximum flight speed is about 1,000 km/h. “Hunter” first took to the air on August 3, 2019, the flight lasted more than 20 minutes under the control of the operator. On September 27, 2019, the UAV performed a joint flight with the Su-57 fighter. Serial production of the drone is scheduled to begin in 2023.
