Su-34

 

The Su-34 fighter-bomber is designed to destroy ground, surface and air targets, infrastructure facilities covered by air defense systems and located at considerable distances from the home airfield, with enemy fire and information countermeasures, day and night in simple and difficult meteorological conditions, using unguided and guided aircraft weapons, as well as to perform aerial reconnaissance missions.

One of the first confirmed combat uses of the Su-34 fighter-bomber was the operation of the Russian Aerospace Forces to combat international terrorism in the Syrian Arab Republic, which began on September 30, 2015. The successful use of Su-34 aircraft in the Syrian Arab Republic served as an impetus for intensifying negotiations on the supply of this aircraft to the foreign market: a number of countries have expressed interest in buying an export version of Su-34 aircraft for their Air Force.

The main features of the Su-34 fighter-bomber and its export modification Su-32 are:

large combat load and a wide range of guided aircraft weapons;

high transport capabilities of the aircraft;

Increased degree of autonomy of basing;

availability of an in-flight refueling system;

· increased combat survivability (booking of the cockpit and vital systems, increased explosion safety due to protection and filling of fuel tanks with polyurethane foam);

· open architecture and a powerful avionics complex, including a multifunctional radar with phased array, a built-in laser television guidance station and a set of electronic warfare equipment;

· A modern display system in the cockpit using multifunctional indicators with a push-button frame.

The crew members of the Su-34 aircraft are placed in the cockpit according to the “side by side” scheme. The aircraft is equipped with a front horizontal tail to ensure stable flight at all altitudes and speeds, including extremely low ones. The layout of the head part of the fuselage provides increased comfort for the crew members: the height of the cockpit in its seat allows the pilot to stand up to his full height and perform a warm-up; Living conditions in the cockpit allow pilots not to lose their working capacity during long flights up to 10 hours.

To increase the survivability of the Su-32 crew when overcoming enemy air defenses and performing a long flight at low and ultra-low altitudes, where portable anti-aircraft missile systems and small arms pose the main threat, the cockpit is made in the form of a titanium armored capsule. Other vital aircraft compartments are also armored.

To ensure the specified range and flight duration, the Su-32 is equipped with an in-flight refueling system. The fuel receiver rod is located in the head part of the fuselage on the left side.

The Su-32 aircraft is equipped with one of the latest modifications of the K-36D-3.5E ejection seats manufactured by Zvezda Research and Production Enterprise OJSC, which ensure safe emergency escape of the aircraft by the crew in the entire operational range of altitudes and speeds, including aircraft parking on the ground.

A distinctive feature of the Su-32 is the enlarged central tail boom, which houses the auxiliary power unit, braking parachute, ECM consumables ejection devices and an additional fuel tank.

The power plant of the aircraft is represented by two turbojet engines AL-31F series 23 developed by the A. Lyulka Experimental Design Bureau. Engine thrust in the "full afterburner" mode is 12500 kgf, in the "maximum" mode - 7770 kgf.

In order to increase the autonomy of basing, the power plant of the Su-32 aircraft included the auxiliary power unit TA-14-130-35, developed by JSC NPP Aerosila.

One of the key factors that made it possible to significantly increase the efficiency of combat missions by the Su-32 aircraft is the use of a fundamentally new complex of avionics equipment. At the same time, the Su-32 aircraft became the first Russian combat aircraft designed on the principle of an open architecture of the on-board radio-electronic complex. This means that the integration of new equipment on board does not require a radical revision of the entire complex.

The on-board radio-electronic complex installed on the Su-32 aircraft meets all the requirements for modern tactical aircraft. The complex includes:

· multifunctional forward-looking radar with a phased antenna array;

· optical-electronic sighting and navigation system;

complex of electronic countermeasures.

The Sh-141-02E multifunctional radar station with a phased array antenna, manufactured by OAO TsNPO Leninets, provides detection of fighter-type air targets at ranges up to 120 km. Viewing angles are ±60°. The number of simultaneously tracked air targets by the radar of the Su-32 aircraft reaches 10, while the aircraft can simultaneously fire at 4 of them.

In the air-ground mode, the radar provides:

detection of a target of the “railway bridge” type at ranges up to 100 km;

Simultaneous tracking and firing of 4 ground targets;

high-resolution mapping of the earth's surface.

For survey of the earth's surface and guidance of guided and unguided weapons, a laser television sighting station "Platan" developed by JSC "PA" UOMZ "installed in the lower part of the fuselage is used.

The station has television and laser channels and provides:

search, detection and recognition by the navigator of ground (surface) targets from a television image;

· automatic and software-corrected tracking of ground (surface) moving (fixed) targets on a television image;

· measurement of range on the laser channel of targets for the use of controlled and uncontrolled ASP;

· laser illumination of ground (surface) targets for targeting guided aircraft weapons with laser seekers;

· detection and tracking of a laser spot on a target when the target is illuminated from an external source and guidance of controlled ASPs with laser seekers.

The electronic warfare complex of the Su-32 L-175VE aircraft developed by KNIRTI JSC is a highly intelligent system of individual mutual protection of the aircraft, which provides electronic suppression of enemy radars and the use of anti-radar missiles against radio-emitting targets.

The Su-32 is equipped with the S-103 communication complex developed by Polet Research and Production Enterprise JSC, designed for radio communication between aircraft crews and ground control points, telecode radio communication between aircraft, as well as ensuring group operations as part of an autonomous group and operations of a pair of aircraft.

The on-board navigation system of the Su-32 aircraft with a digital multiplex information exchange channel ensures round-the-clock and all-weather combat use of air bombs against radio-contrast targets with aiming through radar, the use of high-precision destruction of the entire range of air bombs, the use of unguided aircraft missiles, as well as a wide range of guided weapons air-to-surface class.

Much attention is paid to ensuring situational awareness of the pilot and navigator. All information in the cockpit is displayed on five color multifunctional indicators MFI-66 with a push-button frame. When information is output to the MFI, the principle of "the right information at the right time" is implemented, which greatly simplifies the control of the aircraft in the piloting mode and solving problems of combat use. In the event of failure of the MFI, flight information is duplicated on backup mechanical instruments. In addition, the pilot has a KAI-1-01 collimator aviation indicator, which displays flight and navigation information, and during the performance of combat missions - aiming information. To ensure better situational awareness of the crew, a voice warning system is installed on the aircraft.

A distinctive feature of the Su-32 is the use of a wide range of both guided and unguided weapons. Armament is placed on 12 suspension points, while active jamming station containers are permanently placed on the end suspension points.

To destroy air targets, short-range air-to-air missiles with an infrared homing head R-73E and RVV-MD - up to 6 pieces, as well as medium-range air-to-air missiles with an active radar homing head RVV-AE - also up to 6 pieces.

To destroy the radar, the Su-34 can carry up to 6 Kh-31PD supersonic anti-radar missiles with a passive homing head.

Surface targets are hit by up to 6 supersonic Kh-31A and Kh-31AD anti-ship missiles, as well as up to 6 Kh-35UE subsonic missiles and up to 3 Kh-59MK missiles.

The range of guided weapons for destroying ground targets is represented by Kh-38MLE missiles with a laser guidance head (up to 6 pieces) and Kh-59M2E missiles with a television-command guidance system (up to 3 pieces). Also, the guided weapons include 500-kilogram guided bombs KAB-500KR and KAB-500OD with a television guidance system and KAB 500S-E with a satellite guidance system (up to 6 pieces). Adjustable bombs of 1500 kg caliber - KAB-1500KR with television guidance (up to 3 pieces) and KAB-1500LG-F-E with laser guidance (up to 3 pieces) are used to destroy especially important objects.
