sukhoi

Sukhoi Su-27 (NATO: Flanker) fighter aircraft which was originally produced by the Soviet Union, and designed by the Sukhoi Design Bureau. The aircraft is planned to be the main rival of new generation fighter aircraft of the United States (ie F-14 Tomcat, F-15 Eagle, F-16 Fighting Falcon, and F/A-18 Hornet). Su-27 has a reach far distances, the heavy weapons, and high agility. The aircraft is often referred to as a result of competition between Sukhoi with Mikoyan-Gurevich, because the Su-27 and MiG-29 shaped like. This is wrong, because the Su-27 aircraft was designed as interceptors and air superiority fighter distance, while the MiG-29 is designed to fill the role of supporting fighters at close range.

History

In 1969, the Soviet Union was informed that the United States Air Force has selected McDonnell Douglas to produce the design of experimental aircraft (which will evolve into the F-15). To face this future threat, the Soviet Union began a program of PFI (Perspektivnyi Frontovoy Istrebitel, "advanced tactical fighter plane") which is planned to produce aircraft that could compete with the United States draft.

However, the specifications needed to meet the requirements of this program on a single plane was too complicated and expensive. So this program is divided into two, namely TPFI (Tyazholyi Perspektivnyi Frontovoi Istrebitel, "advanced tactical fighter aircraft weight") and the LPFI (Legkiy Perspektivnyi Frontovoi Istrebitel, "advanced tactical fighter aircraft light"). This step is also similar to what the United States, where the United States began a program of "Lightweight Fighter" which will produce F-16. Sukhoi OKB was given TPFI program.

Sukhoi design first appeared as a delta wing aircraft T-10, which first flew on 20 May 1977. T-10 seen by Western observers, and given NATO reporting name Flanker-A. The development of T-10 encountered many problems, which resulted in the destruction of the aircraft when one of this falls on May 7, 1978. This incident then followed up with a lot of design modifications, which produces T-10S, which first flew on April 20, 1981. This aircraft also had difficulty, and fell on December 23, 1981.

Production version of this aircraft (Su-27 or Su-27s, with code Flanker-B NATO) begins to use the Soviet Air Force in 1984, but only used overall in 1986, as had hampered by production problems. The aircraft was used by the Soviet Air Defense Anti (Voyska PVO) and the Soviet Air Force (VVS). Use the V-PVO is as interceptors, replace the Sukhoi Su-15 and Tupolev Tu-28. And its usage in VVS is more focused on air interdiction, with the task of attacking aircraft fuel and AWACS, which is considered as an important asset of NATO air forces.

Aerodinamisasi basic design of the Su-27 is similar to the MiG-29 only bigger. This aircraft is so great that to alleviate the weight of the titanium materials are used (about 30%). no composite materials are used. Sayung wing backs together with extension of the fuselage at the leading edge and basically the delta-shaped wings, only the outer edge are cut to the wing tip missile rails. Su-27 is not a pure delta aircraft still retain a conventional tail shape, by using the vertical tail fins 2 on the outer side of both engines, and assisted with the 2 tail folded down to help lateral stability.

Lyulka turbofan engines AL-31F provide a very wide place, where the width is provided for security reasons and to ensure that air flow is not interrupted at the air intake openings. The room is created between the two machines also provide additional lift, thereby reducing the burden of the wing. Channel guide that can be mobilized in the openings allow air to enter the aircraft reaches a speed of Mach 2 +, and helps maintain engine airflow at the corner of the screen tinggi.Sebuah alpha filter is placed on the air intake openings to protect the engine from dirt during takeoff.

Su-27 is the first operational flight of the Soviet Union that uses flight control systems fly by wire, was developed based on experience in project Sukhoi OKB Sukhoi bomber T-4. This system combined with my burden is relatively low and the basic flight controls are strong, it produces exceptional aircraft lively, still easily controlled even at low speeds and decreasing sanagat high attack. In aerospace exhibition, the plane was able to demonstrate the maneuverability with the action "patukan cobra" (Pugachev Cobra) or dynamic braking - to maintain level flight at an angle of attack 120 °. Steering jets also spray at trial and was applied to the late models of Su-30MKI and Su-37, allowing the plane to turn sharply to almost zero turn radius, using the technique of the vertical somersault back into alignment movement and limited float plane nose facing upwards.

Marine version of the Flanker (better known as Su-33), using kanard for additional lift, reducing takeoff distance (very important for ships that operate from aircraft carriers without catapults system, the Admiral Kuznetsov). Kanard is also used in some Su-30, Su-35, and Su-37.

In addition to agility, Su-27 uses a large internal volume for storing fuel in large numbers too. In excess configuration for maximum distance, the plane was capable of carrying 9400 kg of internal fuel, however, with the burden of such a limited maneuverability, and the normal load is 5270 kg.

Su-27 armed with a cannon-Shipunov GSH Gryazev-30-1 caliber 30 mm at the base of the wings, and has a hook 10 to the missile weapons and other weapons. Standard missile weaponry to combat air-to-air missile is a mixture of Vympel R-73 (AA-11 Archer) missiles and Vympel R-27 (AA-10 'Alamo'), the last weapons have a version diperjauh mileage and infrared control model . Flanker variants is more sophisticated such as Su-30, Su-35, and Su-37 can also carry missiles Vympel R-77 (AA-12 Adder).

Su-27 has a head up display, high contrast and can adjustable sights mounted on the helmet, which, when paired with R-73 missiles and agility of a very high plane makes this aircraft one of the best aircraft for short range air combat.

Radar Su-27 proved to be a major problem in the development of the Su-27. Initial request of the Soviet Union was very ambitious, hoping to ambush Traffic and multi-target distance of 200km to monitor the size of a bomber aircraft (RCS 16 square meters for a Tu-16). This will exceed the detection ability of the APG-63 radar from the F-15 (approximately 180km to the target RCS to 100 square meters) and the ability of Su-27 radar is approximately equivalent to phased array radar Zaslon weighing 1 ton used in the aircraft MiG -31.

Although the Su-27 is considered to have amazing agility, the plane was not yet widely used in the actual petempuran. Use of this aircraft is worth called on Ethiopia-Eritrea War, where the planes Sukhoi Su-27A Ethiopia used to protect the bombers and MiG-21 MiG-23. In war, the planes Su-27 is able to destroy four Eritrean MiG-29.

One of the pilots who managed to shoot down your opponent is Tolossa Aster, who became the first African woman to win an air battle.

Around 680 Su-27 is produced by the Soviet Union, and 400 used by the Russians. Former Soviet countries that have this plane is 60 aircraft with Ukraine, Belarus with about 25 aircraft, Kazakhstan with about 30 and has ordered another 12 aircraft, and Uzbekistan with 25 pieces.

China received 26 aircraft in 1991, and 22 more in 1995. Then in 1998 they signed a contract to license production of 200 aircraft with a Shenyang J-11. Vietnam has 12 Su-27SK and has ordered 24 more. 8 Ethiopia has 27A and Su-2 Su-27U. Indonesia has 2 Su-27SK and 2 Su-30MKI and has ordered 6 more. And Angola has received about 8 Su-27/27UB. Mexico plans to buy 8 Su-27s and 2 aircraft Su-27UB training. [1]

The United States also allegedly had a Su-27 Flanker B and one Su-27 UB. Three aircraft are entered as civil registration, and one of them arrived in the United States using Antonov-62 aircraft.

Indonesia (TNI-AU) began using Sukhoi-27 family in 2003 after the cancellation of the contract purchase 12 Su-30MKI units in 1996. Contract year 2003 include the purchase of 2 units of Sukhoi-27SK and 2 units of Sukhoi-30MK worth 192 million U.S. dollars without weapons package. Four years later the MAX 2007 event in Moscow Department of Defense announced the purchase contract for junior fashion Sukhoi-3 units and 3 units 27SKM Sukhoi-30MK2 worth 350 million U.S. dollars.
