DESIGN AND FEATURES:

The Su-34 design retains the basic layout and construction of the Su-27 airframe. It has canards wings like su30mki. It has an entirely new nose and forward fuselage with a cockpit providing side-by-side seating for a crew of two. . It has a two-seat rather than single-seat cockpit. The Su-34 has a changed contour of the nose section to accommodate an advanced multi-mode phased array radar with terrain following and terrain avoidance modes.

The Su-34's most distinctive feature is the unusually large flight deck. Much of the design work went into crew comfort. The two crew members sit side by side in a large cabin, with the pilot-commander to the left and navigator/operator of weapons to the right. An advantage of the side by side cockpit is that duplicate instruments are not required for each pilot. The crew members have room to stand and move about the cabin during long missions

su-34's cockpit

The  cockpit  of su32/34 uses a single dual combiner Head Up Display, and AMLCD displays. The widely photographed prototype cockpits are unlikely to represent a production configuration, given the layout of the more recent Su-30MK and Su-27SKM/SKU glass cockpits. The multifunction displays in the cockpit show the flight parameters, the operational status of the aircraft units and tactical data.

Armaments’ and sensors

The primary aircraft sensor is the large Leninets B-004 multimode phased array radar. The X-band design is claimed to achieve a 15 kW peak power rating. The radar is claimed to provide a range of 200 to 250 km against large surface targets, ground mapping capability to 150 km .Defensive systems include a Radar Warning Receiver, most likely the current variant of the SPO-32 / L150 Pastel digital receiver carried by the Su-27/30.

The Su-34 has 12 pylons for up to 8,000 kilograms of ordnance, intended to include the latest Russian precision-guided weapons. The Su-34 is armed with a 30mm GSh-301 gun and 180 rounds of ammunition. The gun has a maximum rate of fire of 1,500 rounds a minute and the muzzle velocity is 860m/sec. it is able to carry a range of missiles including air-to-air, air-to-surface, anti-ship and anti-radiation missiles, guided and unguided bombs, and rockets. The aircraft is fitted with a target designator.

First production aircraft are powered by two after-burning NPO Saturn AL-31F turbofan engines. Later aircraft may be fitted with MMPP Salyut AL-31F-M2/3 or NPO Saturn 117 engines.

SUKHOI SU-37

The new multirole all-weather super-agile fighter  SUKHOI SU-37( FLANKER F) with thrust vector control (TVC) represents a logical step forward in the steady implementation by the Sukhoi EDB of a development program of fourth and fifth generation of tactical aircraft from the basic Su-27 fighter for the Russian Air Force. As announced by General Designer Mikhail Simonov, the new fighter is related to "the fourth with two pluses" generation. This is the latest, although far from the last, Sukhoi's development. 
Its An aircraft which created a new term in aircraft technology called Super Maneuverability.

The Su-37 has a lot of new features when compared to its earlier models this include better fly-by-wire system, two dimensional thrust vectoring system and a digital cockpit. .The new feature of the super-maneuverable Su-37 fighter is the two-dimensional thrust vector control engines, which allow the aircraft to recover from spins and stalls at almost any altitude, while it is also equipped with full digital fly-by-wire controls.

According to Mikhail Simonov, the aircraft has virtually no angle-of-attack limitations. It can fly flatwise to the air stream, with its tail forward, i. e., with 90 and even 180 deg angles of attack. It can locate targets with its radars and attack them with its weapons from any position. This feature is extremely important for both air combat and the evasion of enemy missile attacks. "The Su-37 is a multirole, all-weather fighter aircraft demonstrator."

Engines:

The Sukhoi designs are famous for their efficient engines which are capable to withstand any situation during flight and their fuel efficiency. The Su-37 is powered by two AL-31FU TVC (thrust vector control) turbofan engines. This engine was developed by the Lyulka Engine Design Bureau (NPO Saturn) and is a derivative of the AL-31F twin-shaft turbofan engine on the Su-27.

Each engine provides 83.36kN thrust and 142kN with the afterburner and is steerable from -15° to +15° along the vertical plane. This allows the Su-37 to recover form stalls with relative ease. Both the nozzles of the engines can be deflected in the same direction or in different direction which gives the Su-37 much greater manoeuverability and agility.

Avionics

The Su-37 is fitted with a NO-11M pulse Doppler phased array  radar which is manufactured by NIIP. This radar can track up to 15 targets simultaniously and designate them. The Su-37 also has a rear looking NO-12 radar for fire control and surveillance. There are also systems for terrain-following and terrain-avoidance, mapping and multichannel employment of guided weapons.

The following features clearly set this aircraft apart from the others: 
   - capability to deliver a preemptive strike at any air target, including hard-to-detect ones; 
   - exceptionally high performance; 
   - phenomenal agility; - multichannel redundancy and algorithmic protection of all information and aiming systems; 
   - ground target attack standoff range capability; 
   - terrain following and ground obstacle avoidance capability; 
   - automated group actions during attacks at air and ground targets; 
   - ability to counteract enemy ECM and optronic means; 
   - automation of all phases of flight and combat employment.

Sukhoi Su-35 (Flanker-E)

The Su-35 is a 4++ generation aircraft employing technologies of the fifth generation. The aircraft is almost superior to all other 4th generation fighters now under development worldwide.

The Sukhoi Su-35 (Flanker-E) is a single-seat, twin-engine supermaneuverable multirole fighter. It is a derivative of the Su-27 'Flanker', and was initially known as the Su-27M.The first experimental Su-35, completed in summer 2007 and first appeared at Russia’s MAKS-2007 air show. . The Export configurations were designated Su-35. This aircraft was used as the basis of the Su-37 Flanker F advanced technology demonstrator, often labelled as the Super Flanker.  

What’s New in Su35S from Predecessors?

The impressive Su-35S is the latest incarnation of the T-10 family of fighter aircraft. It would be fair to describe this aircraft as the pinnacle of current conventional fighter design, blending a superb basic aerodynamic design with advanced engine, flight control and avionic technology.

What is new in the Su-35? First off, the fighter will get an improved airframe, which will dramatically increase its service life to 6,000 hours, 30 years of operation (the time before the first test and recondition and the between-repairs period has been increased to 1,500 hours, or 10 years of operation). Aerodynamically it is similar to the Su-27. But unlike the Su-30MKI it will feature no canard fins. All the three channels will have electrically signaled control without mechanical cabling. The use of a new integrated control system (developed by MNPK Avionika Moscow-based Research and Production Association) simultaneously performing functions of several systems – remote control, automatic control, limiting signals system, air signals system, chassis wheels braking system – will enhance the fighter’s handling capability and maneuverability. Notable changes include the removal of the dorsal speedbrake, additional internal fuel, and plumbing for AAR and external drop tanks. . A quadruplex digital flight control system is used. The Item 117S engines, which use key components of the Al-41F supercruising core, are employed.

Another important difference of the Su-35 from predecessors from the Su-27 family is the use, in its power plant, of new engines with an increased thrust. Those engines, known as 117S, have been developed by NPO Saturn Research and Production Association.

The Su-35S is the first non-US fighter with substantial sustained supersonic cruise capability, which provides this aircraft with an enormous energy advantage against conventional opponents in most regimes of air combat.

Aircraft’s Engine

the new engines, known as 117S are used in su35s.the engines are substantially modified AL-31F production engines employing fifth-generation technologies. They use a new fan, new high and low pressure turbines, and a new digital control system. A provision is made for using a vectored thrust nozzle. The modernization has increased the engine special mode thrust by 16%, up to 14,500 kgf. In the maximum burner-free mode it reaches 8,800 kgf. Compared to today’s AL-31F engines, their capabilities will grow substantially, by 2 to 2.7 times.

Avionics And Radar

The avionic suite is fully digital. . A new glass cockpit is employed, using large area displays. The Khibiny electronic warfare suite is employed, with new wingtip DRFM technology jamming pods.

The core of the Su-35 armament is a new radar control system with a phased antenna array (Irbis-E). It features unique capabilities in terms of the target detection range.IT CONSISTING an X-waveband multi-role radar with a passive phased antenna array (PAA). Irbis-E radar control system detects and tracks up to 30 air targets, retaining continuity of space observation and engaging up to eight targets. The system detects, chooses and tracks up to four ground targets in several map-making modes with various resolution at a range of up to 400 km, without stopping to monitor the airspace.
