Structural features of the Su 27 fighter

<> "Su-27 fighter.

The Su-27 is a single-seat twin-engine all-weather air superiority heavy combat aircraft developed by the Sukhoi Design Bureau of the former Soviet Union, and its main tasks are territorial air defense, escort, and maritime patrol. The nickname given by NATO is:"Flanker"（flanker）.The aircraft began to be developed in 1969, made its first flight on May 20, 1977, was put into mass production in 1979, and entered the army in 1985.

There are many members of the Su-27 series fighter family, and the main models are Su-27 (early air force type), Su-30 (ground attack type upgraded on the basis of Su-27), Su-33 (aircraft carrier-based type), Su-35 (multi-functional fighter) and so on.

Key data Members: 1 to 2 people; Length:; Wingspan:

17450kg；Maximum take-off weight: 33000kg; Maximum fuel load: 9400kg (internal); Maximum external load:

8000kg；2 Russian-made Al-31 series turbofan engines; 10 external hardpoints: 2 wingtip hardpoints, 4 lower wing hardpoints, 4 belly hardpoints.

Development history The development of the Su-27 fighter began in the 1970s, and the first Su-27 prototype, the T-10-1, left the factory in early 1977, and was tested by test pilot Ilyushin on May 20 of that year at the Rukovsky Flight Test Center near the city of Ramenskoe.

At the beginning of 1978, the T-10-1 was first photographed by American reconnaissance satellites, and because of the mistake of Rukovsky for the Raminsky base, the Americans called this never-before-seen aircraft the Ram-K. In 1978 the T-10-2 appeared, but crashed soon after due to a malfunction of the fly-by-wire system. A total of 10 T-10s were built, and the handling used a fly-by-wire flight control system, which was different from previous Soviet-made aircraft.

Equipment. The Soviet Union and Russia built 680 Su-27s, which only refer to the Su-27 and do not include later derivative models. In addition to the Su-27, Russia is armed with 19 Su-30, 28 Su-33, 30 Su-34 and 11 Su-35.

Ukraine has 80 Su-27s inherited from the former Soviet Air Force, and after years of negotiations, India has replaced 40 Su-30MKIs with more powerful AL-31FP engines, avionics, canards, and thrust vectoring nozzles. Hindustan Aeronautics has also received a production licence to produce an additional 140 flights by 2020.

The Su-27 fighter, codenamed "Flanker" (Flanker), is a single-seat, twin-engine all-weather heavy fighter designed by the Sukhoi Design Bureau during the Soviet era.

The Su-27 fighter is a heavy fighter designed and manufactured by the Soviet Union, and the imaginary enemy is the US F-15 fighter. In the 60s of the 20th century, the United States successively launched the development program of F-15 and F-16 fighters, so the Soviet Union also began to launch the Future Front-line Fighter Program (PFI) in 1969.

The Su-27 fighter is tall and powerful, and because it has a traditional horizontal tail, it is not a real delta-wing aircraft. In addition, there are a pair of vertical rear wings on the outside of the engine's gear grip and a pair of tail fins that extend downward for added lateral stability.

The Su-27 fighter has a very smooth aerodynamic shape and excellent maneuverability, and it is still equipped with the first practical application of the Su-Ru Fool Finger Link's wire-by-wire flight control system, with relatively low wing load and strong basic flight control, the aircraft is extremely flexible, even at extremely low speeds and high angles of attack. At the Paris Air Show in 1989, the Su-27S surprised the audience with a very difficult Pugachev Cobra maneuver, which brought great shock to the aviation industry.

Basic parameters: production quantity: 680 aircraft.

Captain: m.

Maximum range: 3530 km.

Machine height: m.

Maximum speed: 2500 km/h.

Wingspan: Slag with rice.

Ceiling: 19,000 meters.

The Su-27 fighter is a heavy fighter designed and manufactured by the Soviet Union, the imaginary enemy is the US F-15 fighter, in the 60s of the 20th century, the United States has launched the development plan of the F-15 and F-16 fighters, so the Soviet Union also began to launch the future front-line fighter program (PFI) from 1969.

The Su-27 fighter is tall and powerful, because it has a traditional horizontal tail, so it is not a real delta-wing aircraft, in addition, there is a pair of vertical tails on the outside of the engine, and a pair of tail fins that extend downward to increase lateral stability, the aircraft uses two Lyulka Al-31F turbofan fan engines with large spacing to provide better safety, and there are filters in the air intake tract to prevent foreign objects from being sucked into the engine during takeoff.

The aerodynamic shape of the Su-27 fighter is very smooth, the maneuverability is excellent, and it is still equipped with the first practical application of the Soviet Union's wire-borne flight control system, along with the relatively low wing load, and strong basic flight control, the flexibility of the aircraft is extraordinarily good, even at extremely low speed and high angle of attack can still be controlled, at the 1989 Paris Air Show, the Su-27S made a very difficult Pugachev Cobra maneuver, which shocked the audience and brought great shock to the aviation industry.

1. In terms of the shape of the aircraft, the Su-30 is larger than the basic Su-27, and as a long-range interceptor and combat training aircraft, the Su-30 aircraft mainly has the basic type, type, and type.

2. It is different from the external layout. The cockpit of the Su-30 aircraft is set up as a tandem two-seater nose, and the upper left side of the nose is equipped with a hydraulically retractable aerial refueling head and night air refueling lights, and the lidar is on the right compared with the Su-27 aircraft.

3. From the perspective of the cockpit layout, there are two big differences: one is the addition of the pilot's cabin life system; Second, the rear compartment has added a ground precision strike control handle and a guidance display system to meet the operational requirements of ground attack.
