Specialists of the Novosibirsk Aviation Plant named after V.P. Chkalov conducted frequency response tests of a prototype of the Russian Okhotnik (Hunter) attack drone.
Frequency response tests are conducted as the final stage in aircraft development. They make it possible to eliminate a possibility of dangerous aeroelastic resonant vibrations and obtain data on the vibration of all elements of the airframe structure. Such tests are carried out to predict the behavior of an aircraft in the event of flutter. Such tests are performed with the use of a prototype that has all standard systems and units installed.
The elastic suspension system is designed for jacking aircraft during frequency response tests. The system simulates level flight conditions. The small-sized system makes it possible to conduct frequency response tests of any Sukhoi aircraft.
Earlier, Sergey Chemezov, Director General of the Rostec State Corporation, said that the serial production of Okhotnik drones would begin in 2023.
