Su-27 is a fighter model
The Su-27 is a single-seater dual-engine all-weather air superiority heavy fighter developed by the former Soviet Union’s Sukhoi Design Bureau. Its main tasks are homeland air defense, escort, and maritime patrols. NATO gave the nickname “Flanker” (Flanker). The aircraft began development in 1969, first flew on May 20, 1977, put into batch production in 1979, and entered military service in 1985. The aircraft adopts wing-body fusion technology, a cantilevered single wing, with smoothly curved edge strips outside the wing roots, a normal layout with double vertical tails, and a wedge-shaped air inlet located at the front and bottom of the wing-body fusion. It has good aerodynamic performance. There are grid-type auxiliary doors at the bottom and side walls of the intake duct to prevent foreign objects from being sucked in during landing. The all-metal semi-monocoque fuselage, the nose is slightly downward, and a large number of aluminum and titanium alloys are used. The traditional three-beam wing. More than 4 degrees fly-by-wire control system, no mechanical backup, statically unstable design. The aircraft is mainly designed for the F-16 and F-15 of the United States to replace the Yak-28P, Su-15 and Tu-28P/128 interceptors. It has the characteristics of good maneuverability and agility, and long endurance. Can conduct beyond visual range operations. The “Pugachev Cobra” maneuvers completed by the aircraft showed its excellent flight performance and control performance, as well as good engine acceleration performance. The flight performance is higher than that of the third-generation fighter, but its on-board electronic equipment and cockpit Relatively speaking, display devices lag far behind and have no stealth performance. The aircraft has a variety of modifications, including Su-27P single-seater land-based, Su-27UB tandem two-seater trainer, Su-27K carrier combat/attack, Su-27KU parallel two-seater combat bomber, P- 42 (the aircraft specially modified by the Su-27, which created 31 official world records) and so on. By 1992, the CIS countries had equipped more than 300 Su-27 aircraft, and the aircraft currently produced are mainly for export.
The Su-27 fighter is a long-range fighter designed by the Russian Sukhoi Design Bureau. It was successively equipped with troops in 1986 and is currently the main combat aircraft of the Russian Air Force.
The aircraft has a length of 21.935 meters, a wingspan of 14.7 meters, a height of 5.932 meters and a maximum take-off weight of 29,000 kg. It is equipped with two turbofan engines with a thrust of 13,500 kg, with a total thrust of 27,000 kg and a maximum flight speed of 2.35. The radius is 1500 kilometers.
The Su-27 aircraft adopts dual vertical tail layout and advanced aerodynamic technology of wing-body fusion. The square binary air inlets placed on both sides of the fuselage have adjustable air inlet sloping plates and are equipped with more than four degrees of fly-by-wire control. system. Good aerodynamic shape and control quality can change the flight attitude of the aircraft in front of the nose. At the Paris Aerospace Exhibition in 1989, Pugachev drove the Su-27 aircraft with the tail forward and the nose tilted back. The maximum angle of attack was 110°-120°. Without stalling at 125 kilometers, it caused a sensation in the aviation industry of Western countries.
