Su-24 Avionics

In addition to weapons, the aircraft was carrying and reconnaissance equipment, represented a pretty old aerial cameras AFA-39, is most often used for fotokontrolya results "work" (for reconnaissance, he was considered underpowered). AFA was mounted in the lower part of the fuselage. Targeted use of AFA produced according reticle "The Seagull."

Sighting and navigation system PNS-24 includes a low-altitude circuit IAC, which provides automatic execution of the flight on a given route at low altitude terrain following flight or semi-(-director) mode. The Su-24 was the first Soviet aircraft specially designed for operations at extremely low altitudes - it was laid in the original draft C-6.

In addition, part of the PNS-24 "Puma-A" were: small-sized inertial IIA-P, monopulse radar CPF "Relief" (used as a rangefinder in the ERM and aiming), Doppler ground speed and drift angle DISS-7, altimeter altimeters RV-ZMP and greater heights PB-18A, an input-output UVV "Bean-A." Management NTC-24 carried out a digital computing device CWU-10-058M "Orbit-10." It was specially designed for the modification of the Su-24 family of computers "Orbit" is installed on many Soviet aircraft of the period. Also on board were the traditional means of navigation - Automatic Direction Finder ARK-10, and later, the ARC 15 and marker radio MCI-56P, the aircraft radio equipment range navigation system RSBN-6C "Diamond-1K".

The Su-24 was installed automatic control system SAU-6. It could deal with complex navigational and tactical problems, but at the start of receipt of the aircraft in combat units was still very "raw". The trial lasted until 1976. By the time of ACS managed to bring the level up to the standards adopted in the USSR.

Such a wealth of electronics, of course, aroused respect. But as always, there was another side - the electronics were often inoperable and a sensible approach to the architecture of the control system of the aircraft avoided flying accidents failures in ACS circuits.

The persistence and unpretentiousness aircraft avionics is proved that there was a possibility of further operation of the machine without hatches, non-power panels and sealing devices. The pressure generated by the velocity head in the compartments, sometimes reach enormous sizes.
