The digital architecture of the new fifth-generation Su-57 fighter is built on the principle of integrated modular avionics. Engineers at the Sukhoi Design Bureau abandoned disparate computing units in favor of a single distributed onboard information network.
The central computer of the system is based on Russian multi-core processors, providing processing of large amounts of data in real time.
The exact number of computing modules and their characteristics are not disclosed, but it is known that the system implements redundancy of transmission channels and computing power, which significantly increases the fault tolerance of the IUS-57.
The system uses a duplicated digital bus MIL-STD-1553B with an extended bandwidth of up to 1.2 Gbps in a modernized version.
The Su-57 uses a combined digital architecture: copper lines (MIL-STD-1553B) — for controlling critical systems (duplication) and fiber optics — for high-speed flows (optoelectronic radar system and data exchange with drones).
Earlier www1.ru reported that new Tor-M2 air defense systems will be adapted to destroy kamikaze drones.
