Design and development
On 14 May 1953, the Sukhoi OKB was reopened and initially tasked with copying the American F-86 Sabre fighter. Events 1264 - Battle of Lewes: Henry III of England is captured in France making Simon de Montfort the Year 1953 ( MCMLIII) was a Common year starting on Thursday (link will display full calendar of the Gregorian calendar. Sukhoi ( Сухой) is a major Russian manufacturer famous for its fighters OKB is a transliteration of the Russian acronym for "Опытное конструкторское бюро" - Opytnoe Konstructorskoe Byuro, meaning The United States of America —commonly referred to as the WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout [1] By the summer, the OKB began work on a swept-wing tactical fighter for establishing air superiority over the battlefield (frontovoi istrebitel, фронтовой истребитель, front-line fighter in Soviet terminology). The first prototype, designated S-1, was designed to use the new Lyulka AL-7 turbojet and it was the first Soviet aircraft to utilize the all-moving tailplane and a translating centerbody, a movable cone in the air intake for managing airflow to the engine at supersonic speeds. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout For other uses see Supersonic. The term supersonic is used to define a speed that is over the Speed of sound ( Mach 1 [2] The aircraft also had a dramatic wing sweep of 60°, irreversible hydraulically boosted controls, and an ejection seat of OKB's own design. In Aircraft, an ejection seat is a system designed to rescue the pilot or other crew of an aircraft (usually military in an emergency [1]
The S-1 first flew on 7 September 1955 with A. Events 1251 BC - A Solar eclipse on this date might mark the birth of legendary Heracles at Thebes Greece. Year 1955 ( MCMLV) was a Common year starting on Saturday (link displays the 1955 Gregorian calendar) G. Kochetkov at the controls. Fitted with an afterburning version of the AL-7 engine after the first 11 flights, the prototype set a Soviet speed record of 2170 km/h (1,170 knots, 1,350 mph, Mach 2.04) in April 1956. The AfterBurner is a lighting solution for the Game Boy Advance system that was created by Triton-Labs Mach number (\mathrm{Ma} or M (generally ˈmɑːk sometimes /ˈmɑːx/ or /ˈmæk/ is the speed of an object moving through air or any Fluid [2] The prototype was intended to be armed with three 30 mm Nudelman N-37 cannon and 32 spin-stabilized 57 mm (2. The N-37 was a powerful 37 mm Aircraft Cannon used by the Soviet Union. 25 in) unguided rockets in a ventral tray. [2] The second prototype, S-2, introduced some aerodynamic refinements. Testing was complicated by the unreliable engine and S-1 was lost in a crash on 23 November 1956, killing its pilot I.

Sokolov. [1] The aircraft entered service as Su-7 in 1959, although it saw only limited operational use.
On 31 July 1958, Soviet tactical aviation (Frontovaya aviatsiya, фронтовая авиация) tasked Sukhoi with developing a ground-attack version of the Su-7. Events 30 BC - Battle of Alexandria: Mark Antony achieves a minor victory over Octavian 's forces but most of his army subsequently Year 1958 ( MCMLVIII) was a Common year starting on Wednesday (link will display full calendar of the Gregorian calendar. The resulting S-22 retained the basic layout of its S-2 predecessor, incorporating primarily structural refinements for high-speed low-altitude operations. It first flew in March 1959, and began entering service in 1961 as the Su-7B. [2]
A total of 1,847 Su-7 and its variants were built, of which 691 were exported. [1]
Operational history
The Su-7 saw combat with Egypt in the Six Day War in 1967 and the War of Attrition. Background Suez Crisis aftermath The Suez Crisis of 1956 represented a military defeat but a political victory for Egypt The War of Attrition (מלחמת ההתשה حرب الاستنزاف was a Limited war fought between the Israeli military and forces of the Egyptian Republic The Indian Air Force had lost 19 Su-7s in the 1971 war with Pakistan.
Operationally, Su-7s were hampered by high takeoff and landing speeds dictated by the thin, highly-swept wing. The landing speed of 450 km/h (245 knots, 280 mph) combined with poor visibility from the cockpit and lack of an instrument landing system made for difficult operations, especially in poor weather. The Instrument Landing System (ILS is a ground-based Instrument approach system that provides precision guidance to an Aircraft approaching a Runway [3] In 1961-1962, Sukhoi experimented with blown flaps on S-25 but the benefit was too small to warrant implementation. Blown flaps are a powered Aerodynamic High-lift device invented by the British on the Wings of certain Aircraft to improve low-speed JATO rockets tested on S-22-4 proved more useful and were incorporated into Su-7BKL. JATO may also refer to the group Jews Against the Occupation. Attempts to improve takeoff and landing performance eventually resulted in the Sukhoi Su-17. WikipediaWikiProject Aircraft.
