The Sukhoi Su-17 ( Russian Сухой Су-17 , project designation R ) was the name of a fighter aircraft project at the end of the 1940s . Had the machine been successfully tested, it would most likely have become the first mass -produced Soviet supersonic aircraft.
development
Pavel Sukhoi began construction work in 1948. He planned the Su-17 as a middle- wing aircraft with very strongly swept wings (50 °) and a very small fuselage cross-section. As a special rescue system, for the first time in the history of military aviation, the machine received a detachable nose section next to the catapult seat, which in the event of an emergency would have been separated from the aircraft by pyrotechnic charges and, together with the pilot , would have come to earth as an escape capsule on parachutes . A model was completed in December 1948 .
In the summer of 1949, flight tests were to begin, but the ZAGI , which was responsible for safety issues, refused to allow the Su-17 to operate because of concerns about the single-spar wings. Since the OKB Sukhoi had been dissolved around the same time , this aspect could no longer be changed and the Su-17 was handed over to the flight test institute of the aviation industry. A few more attempts were made there with the rescue system until the Su-17 was used for fire attempts and was destroyed in the process.
Pavel Sukhoi used the Su-17 as a template for the Sukhoi Su-7 , which marks the beginning of the well-known fighter-bomber series from the Sukhoi design office.
A swing-wing fighter-bomber was later given the serial designation Su-17 .
