Features of the digital architecture of the Su-57 fighter
Integration of sensor systems
The IUS-57 combines data from all of the Su-57's main sensor systems. These include the N036 Belka multifunctional radar, the 101KS-V OELS, and electronic reconnaissance and electronic warfare systems. The Sh-121 radar of the Su-57 aircraft consists of five antennas. An X-band N036-01-1 AESA, two side-looking N036B and N036B-01 AESAs, also of the X-band, are located under the nose cone. Two more N036L and N36L-01 L-band AESAs are installed in the wing tips; they are designed to detect and identify friend or foe targets.
This design solution provides the pilot with all-round visibility, and some tactical features of the aircraft's use allow it to be hidden from ground-based Doppler radars. The site "Aviation of Russia" wrote about this in one of its publications:
If necessary, the system can take control of individual subsystems, freeing the pilot from routine operations. The high degree of automation allows the Su-57 to perform up to 90% of tasks without the pilot's participation. This level of automation reduces the load on him, increases the response speed and minimizes the influence of the human factor.
Mikhail Strelets emphasizes: "We view the aircraft as a platform that can effectively solve its problems for at least 50 years. Including the gradual introduction of next-generation technologies,
essentially transforming the aircraft from generation 5 to 5 plus. This is the generation in which individual sixth-generation technologies are already being introduced."
