Avionics and Equipment
The avionics used in the new jet are a completely new system of onboard electronics. The entire complement of Sukhoi Su-35 electronics is integrated into a single system.
Avionics and other equipment are integrated into a single cohesive system by an information processing and control system, which comprises two digital CPUs, interface and data conversion systems, and a head-up display (HUD) implementing the glass cockpit concept.
The Su-35 has two MFI-35 large color multi-functional LCDs, a multi-functional panel with an integrated display processor, a wide-angle collimated head-up display superimposed over the windscreen and a control panel in the cockpit.
These indicators and a range of other avionics systems of the aircraft were developed by the
Ramenskoye Instrument Design Bureau, also a
Concern Radioelectronic Technologies (KRET) subsidiary.
KRET engineers also designed a new navigation system for the fighter jet – the BINS-SP-2 strap-down inertial navigation system.
The navigation system can identify the aircraft’s location independently from satellite positioning and without communicating with ground-based systems, at accuracy levels double those offered by earlier versions. BINS-SP-2 has an expected operating life of 10,000 hours, nearly double that of currently available comparable navigation systems.
Incidentally, this state-of-the-art navigation system, created from scratch by KRET subsidiaries, will be also used in the Fifth-Generation advanced front-line aircraft system.
Airborne IRBIS Radar
While lacking an APAR, the Su-35 radar system can detect targets at distances up to 400 kilometers, as well as tracking up to aerial targets and engage up to eight of these targets simultaneously.
Sukhkoi Su-35S has owes these capabilities to its new Irbis phased-array radar control system. The system was developed by
Tikhomirov Instrument Engineering Research Institute, a KRET subsidiary, and is being manufactured by the
Ryazan State Instrument Factory, another subsidiary of KRET.
The state-of-the-art system enables Sukhoi Su-35S to detect quickly and track simultaneously up to four ground targets or up to 30 airborne targets, as well as engaging up to eight airborne targets at the same time. Besides, the radar control system has the friend-or-foe identification capability for aerial and maritime objects, is capable of identifying the class and type of airborne targets and take aerial photos of the ground.
The system can be used in any weather at any time of the day, and remain effective in the face of interference, either natural or organized by the enemy electronic warfare systems.
An oscillator with peak power output of 20 kW used in the passive phased array radar makes Irbis the most powerful radar control system in the world.
