The Su-27. A photo. History. Characteristics

 

 

The Su-27 is a multi-purpose all-weather fighter of the Soviet, and later Russian production. It is highly maneuverable flying machine of the fourth generation, developed by the Sukhoi Design Bureau for the total air superiority. The project worked at different times such designers: NS Chernyakov, MP Simonov, AI Knyshev and AA Kolchin. The first OP soared in 1977 year, and five years later the Su-27 entered service of the country. This is the main military aircraft of Russian Air Force.

Since the end of 60-x, in various advanced countries began the race to create a multi-role fighters. The first attack of the USA, trying to create a continuation of the famous F-4C «Phantom." They became established firm "McDonnell Douglas» F-15 «Eagle». In the Soviet Union did not want to retreat and decided to give an adequate response in the form of PFI. Towards a new competitive projects made three OKB Sukhoi Institute did not participate. The engineers were busy going projects: Su-15, Su-17, Su-24, Su-25, T-4 and stowaways LA. But, beginning with 1969 years, engineers from OKB already faced with the development of aircraft such as the perspective of front-line fighter.

The project took into account many factors, not only the advantages of the conquest of the air, but also a factor of possible opponent - F-15. Also included tactics recognized at the time the melee maneuver type. In 72 year there were two scientific and technical meetings with representatives of Yakovlev, Sukhoi and Mikoyan. Representatives Mikoyan carried the proposal to establish the two fighters: light and heavy. Each of them had to perform different tasks.

Began construction of the first prototypes. T-10-1 - OP engines AL-21-F-ADA made its first flight in May 77 year as a test pilot Vladimir Ilyushin. The aircraft was tested for stability, handling and overall performance. The second prototype of the T-10-2, built in a year, came off for long. Once in pitching, construction collapsed because of the enormous congestion. Unfortunately, the test pilot Yevgeny Solovyov died.

T-10-3 developed taking into account the installation of AL-31F, but their unavailability led to the late first flight - 1979 year. The fourth prototype had installed the same experimental radar "Sword". At the end of the year 79 for trial operation were allowed three copies. Initial batch of aircraft was produced at the plant in Komsomolsk-on-Amur. After some time, it was produced five Su-27-type T-105. They are, in addition to flight testing, began to test the service.

In parallel with the development of the Su-27 received timely information about the F-15 American production. According to reports it became clear that the Soviet fighter considerably inferior overseas. These experiments showed that in 1976, the manufacturers of electronic equipment could not meet the scribed their weight and size limits. Radar did not meet all of the specified parameters. It was decided to design the aircraft from the beginning, not leading up to series production.

At no time was designed a new prototype. T-10S-1, piloted by VS Ilyushin took off in April 1981 years. Almost all components have been designed from scratch. The same is affected and the fuselage, for example, initially first wing samples was similar to MIG-29, and a new T-10S it was given a tapered shape. Keely have built on each side of engine, nose landing gear pushed back by three meters. Brake pads located on the bottom of the fuselage, first, the new design they have arranged for the cockpit. Began to open up the canopy. Changed the contours of the bow. The number of nodes on the suspension of missiles increased from eight to ten.

Created a new aircraft not only inferior, but in some situations, and exceeded the overseas competitor. But the engineers did not stop there, as the fighter continues to undergo modernization.

The mass production of the T-10S hit the 1981 year. To him also began to mass-produce the engines AL-31F factories MMPP "Salut" in Moscow and Ufa MPO. The Soviet Air Force planes began delivering in 1982 year. A formal decision of the Government adopted the Su-27 23 entered August 1990 years. During the adoption of the Air Force plane named Su-27S and called in air defense interceptor (Su-27P). It is not used as assault aircraft.

The glider is designed for an integrated circuit such as aerodynamic. Wings seamlessly interface with the fuselage and form a one-piece carrier body. They swept - 42 degree. Aerodynamic characteristics have improved by equipping the root burls great sweep and flap. Sagging helped to increase the aerodynamics at overspeed. On the wing flaperons placed in charge of the simultaneous execution of the functions of flaps and ailerons. The plumage is composed of horizontal type tselnopovortnogo stabilizer. It, in turn, includes two deflectable console. In the symmetrical position, they perform the function of the elevator and the control cores in the differential.

The airframe consists of bow, middle and rear fuselage. The nose is presented in the form of semi-monocoque, the average includes two tank compartment Garrott, right and left of center compartments. To the rear of the nacelle are central tank and the tail boom.

The total weight is reduced by extensive use of titanium - about 30%. Practically not used composite materials. Most modifications horizontal tail often set ahead. This aircraft is the first production aircraft of Soviet production with the presence of wire control system in the longitudinal channel. FBWCS has a maximum speed and precision that solves the problem of rapid reaction during flight.
