The Sukhoi Su-17 ( Russian Сухой Су-17 , NATO code name Fitter ) is a single-jet fighter-bomber that was developed in the Soviet Union during the Cold War . The single-seat aircraft with pivoting outer wings of the Sukhoi family is a further development of the Sukhoi Su-7 B, which in turn emerged from the Su-7.
development
The first production version was the Su-17M, the last version the Su-17M-4. The main difference is the wings of variable geometry, which reduce the landing and take-off speed and increase the range. In contrast to pure swing-wing aircraft such as the MiG-23 and MiG-27, only the outer wings of the Suchoi swing.
The Su-17 was presented to the public in 1969 and entered service in 1971. In the long production phase from 1970 to 1990 there were numerous variants of the basic type. As export versions, the Su-20 and the Su-22 were created based on the Su-17. These were delivered to the Warsaw Pact states and ten other states.
The Su-17 has a single engine that is built into the fuselage of the aircraft. In the prototype and the first pilot series, the AL-7F-1 with 7,000 kg afterburner thrust at sea level was still used. From the first series the AL-21F-3, delivering 11,200 kg of thrust at sea level, was used.
The wings are placed slightly below the center line of the fuselage. The swivel blades can be swiveled manually in a range from 28 ° to 62 °. The wings have continuous slats at the leading edge. Power-controlled ailerons and one-piece slotted flaps are attached to the outside at the rear edge. The slotted flaps are partially retracted into the wing box when the wing is pivoted back. To improve the flow on the wings, two boundary layer fences have been installed per area.
The high profile of the cockpit and the “ridge” that runs along the top of the fuselage between the cockpit and the horizontal stabilizer are striking.
Alongside the MiG-27, the Su-17 represented the backbone of Soviet front- line aircraft in the 1970s and 1980s . Compared to similar aircraft, the Su-17 has a relatively short range, which is why it was intended for use in fighter-bombers near the front.
An aircraft with the designation Su-17 was developed in OKB Suchoi as early as 1949, see:
