Su-34 combat bomber

Development Procedures

In June 1986, the Sukhui Design Bureau began to design a new tactical bomber, the goal is in the 1990s. The mid-stage began to replace the variable-wing Su-24 / 24M "fencing hand" tactical bomber. This kind of aircraft is developed on the basis of Su-27 "side guard", which is called Su -27IB. The first prototype machine inside the code T10V-1 (No. 42), along with the baseline body of Su -27UB "Side-C", but installing the new one with the front body of the flat head, that is, this The flat head, the type has obtained the unofficial nickname of "Duck Beast". T10v-1 completed the general dress in the Moscow experimental plant in the design bureau. On April 13, 1990, the first flight near Moscow, the test flying man is Sukho's Anatoli Ivanov. .

The fuselage design of the second prototype T10V-2 (No. 43) is more refined, and is similar to the later continued pre-production and production. The machine is assembled in the New Siberian aircraft manufacturing plant (NAPO, in 2013), part of the Sukhui company, flying on December 18, 1993. Although the project attaches great importance to the military, due to the turmoil after the Soviet Union and the lack of project funds, the development and test progress of "Duck Beast" is severely delayed. By the beginning of the 21st century, Sukhuoy only manufactured six trial flying machines, two prototypes and four pre-production aircraft, and the number of tested machines caused the national joint test and assessment project to be released. These four pre-production aircraft used in test flights and assessments were T10V-4 / -7 (No. 44-47), successive in December 1994 to December 2000.

With the gradual recovery of the Russian economy, in 2006, Achicbinsk's Russian Air Force 929 National Flight Test Center completed the first phase of the national joint test flight and assessment. Among them, 01 and 03 participated in the national test flight, 02, 04, and 05 machines to Lipttsk participated in the combat assessment of the 4th combat application and the flying personnel rehabilitation center, including development of new tactics, operational technology and rules In addition, these three aircraft are also used in the first batch of modified training in Su-34 units. In 2007, the Russian Air Force began to receive Su-34. He has ordered 124, and the number of receptions will climb year by year. In 2013, 18 receipts were received in 2014. As of December 2018, the Russian Air Force equipped 120 Su-34.

Technical Features

Model structure

Su-34 retains the overall aerodynamic layout of Su-27ub, but the body structure is brand new, this is for Can be placed in front of the front body and nasasal part into the side of the two-seat cabin and the bulky electronic equipment and more fuel. All the main body structure of Su-34 has been strengthened to withstand increased operation weight. Su-34 also retains its predetermined and impressive motorization. A retractable aerial refueling probe on the left side of the nose is standard. Su-34 has a duck wing similar to Su-33 carrier type, which also uses the leading edge strip of Su-33 model, but adds a sharp edge to generate a stable eddy current, and improve the big welcome angle flight. Empty yaw stability. Su-34's front body is much more than Su-27UB, and the duck wing helps to restore pneumatic balance, improve mobile, and reduce the bump caused by chaotic flow in ultra-low empty flights, reducing stress on the fuselage (Duck wing automatic response).

Su-34's new two-wheeled front landing gear backwards, the backband direction is opposite to Su-27. The primary landing gear is installed with a series of two-wheeled to support the increased landing weight and can take off and land on a rough paving runway. Another significant feature is that the tail beam is significantly increased, increasing diameter and length, and additional equipment and systems are installed inside. The deceleration umbrella is located between the back position between the engine compartment, equipped with a dual decrement to shorten the drop slut. The fixed intake port reduces complexity and weight, with powerful engines, which enables "clean" profile to run in the sea level at 1400 kilometers / hour. The body structure is rugged, and it can effectively resist from the light weapon to high energy missile combat section after combining system redundant design. The occupant in the cabin is surrounded by the titanium "bathtub", protecting them from direct injury, and some important systems have corresponding protection.

Cockup design

Su-34 cockpit design also improves the comfort of the unit, the new front body is accommodated in parallel, the pilot is on the left, weapon system operation Cube (WSO) on the right. The occupant can go to the aisle from the ejection seat to stretch the body, and even rest in the long-range task. The K-36DM echo seat has zero / zero eradic capacity, and the left and right seats after the seat cover are energized. The occupant passes through the boarding ladder on the front or falling gear, passing through the cabin on the rear wall into the cockpit. Compared with Su-27UB and Su-30, it can greatly improve the working environment of the crew. In the column cockpit, pilots and weapons system operators can better understand each other in high-load work, because they can fully communicate through the body language, and the reaction time is faster. In addition, the double manipulation control of the cabin is also conducive to the rotation of the unit.

Weapon system

Compared to any other tactical aircraft in Russia, Su-34 can mount more empty guidance weapons. The ammunition can be hung in the fuses of the fuselage, 6 external pits under the wing, and two external pits of the wing tip. When mounting the guided bomb, Su-34 can mount 6 500 kg of KAB-500L or three 1500 kg KAB-1500L laser guidance bombs, or the corresponding KAB-500KR and KAB-1500KR TV development modifications. When mounting short-range empty missiles, Su-34 can mount 6 KH-29L once (AS-14 "Achieve" / KH-25ML (AS-10 Karlen) / S-25LD laser guided missile, or 6 KH-29T TV guided missile. When mounting the remote empty missile, Su-34 can mount 3 KH-59M (AS-13 "Bolt") / KH-59M2 (AS-18 "Reed Flute") TV guided missile, at this time Load a data chain chain to carry out the end of the end.

Su-34 has a powerful anti-ship power, can mount 6 3 Mach of KH-31A /-31AD (AS-17 "") anti-ship missiles at a time. When performing the task of pressing the enemy air defense system (SEAD), 6 KH-31P / -31PM / -31PD high-speed anti-radiation missiles can be mounted once, or KH-58U (AS-11 "Kirt") / - 58USHK Radiation missile. Su-34 can also mount Russia's full range of non-guided bombs and rockets and retain Su-27 standard GSH-301 30mm machine gun. In the machine gun, in the right side strip of the front body, the maximum radio range is 1500 per minute, and the bomb is 150. The 12 weapons of Su-34 can mount up to 8 tons of ammunition, and 9 tons can be hung in overload, but the intake is reduced.

Estate System

Su-34 The most important avionics system is the head of V004 radar, manufactured by St. Petersburg, Heritz Holdings, 1250 × 850 The mime fixed antenna, in addition to meteorological and navigation, also provides a wealth of empty and empty mode. Radars optimized for remote detection and tracking ground and sea surface goals, and the target coordinate can then be booked in precision-made missile drugs. The radar is 150-200 kilometers directed at the small radar cross section (RCS) ground target, and the detection distance of the target of the fighter size is 120 kilometers. When mounting the R-77-1 active radar, the radar can attack two air targets simultaneously in the air mode, and 4 can be attacked simultaneously in empty peer mode.

Secondly, the "Plate" TV / laser optoelectronic system manufactured by the Ural Optical Instrument Factory, which allows the weapon system official to discover and track ground / sea objects during the day and night. "Pratan" can also carry out laser irradiation for laser-made bullets, providing target instructions for photoelectric missile drugs and unmissive missile drugs. "Platte" is built into the front body, there is a vesicable sensor window at the front fuselage and engine air intake port, which can be incorporated with the body, flush with surface to reduce resistance. The sensor assembly also includes a high magnification television camera from the laser range finder / indicator, the maximum detection distance under the optimum visibility conditions is 10 km. The sensor performs front and lower view through three optical glass.
