SU-27

The Sukhoi Su-27 is a Soviet-origin twin-engine supermaneuverable fighter aircraft designed by Sukhoi. It was intended as a direct competitor for the large US fourth-generation jet fighters. The Su-27 was designed for air superiority missions, and subsequent variants are able to perform almost all aerial warfare operations.

Note

The Su-27's basic design is aerodynamically similar to the MiG-29, but it is substantially larger. The wing blends into the fuselage at the leading edge extensions and is essentially a cross between a swept wing and a cropped delta (the delta wing with tips cropped for missile rails or ECM pods). The fighter is also an example of a tailed delta wing configuration, retaining conventional horizontal tailplanes.

The Su-27 had the Soviet Union's first operational fly-by-wire control system, based on the Sukhoi OKB's experience with the T-4 bomber project. Combined with relatively low wing loading and powerful basic flight controls, it makes for an exceptionally agile aircraft, controllable even at very low speeds and high angle of attack. In airshows the aircraft has demonstrated its maneuverability with a Cobra (Pugachev’s Cobra) or dynamic deceleration – briefly sustained level flight at a 120° angle of attack.

The naval version of the 'Flanker', the Su-27K (or Su-33), incorporates canards for additional lift, reducing takeoff distances. These canards have also been incorporated in some Su-30s, the Su-35, and the Su-37.

The Su-27 is equipped with a Phazotron N001 Myech coherent Pulse-Doppler radar with track while scan and look-down/shoot-down capability. The fighter also has an OLS-27 infrared search and track (IRST) system in the nose just forward of the cockpit with an 80–100 km range.
