The Tupolew Tu-82 ( Russian Туполев Ту-82 ) was a Soviet bomber aircraft from the second half of the 1940s and in this capacity the first jet-propelled aircraft of the OKB Tupolev equipped with swept wings .
history
The Project 82 emerged as a parallel draft Tu-14 and was based like this on the Project 72 , which in turn resulted from a requirement of the Air Force for a twin-engine jet bomber from the beginning 1946th The fuselage was largely similar to the Tu-14, had a glazed bow and attached pilot's cockpit and a manned defense post in the stern. Overall, the Tu-82 was kept about four meters smaller in length and wingspan. The two-spar wings used had a sweep of 35 ° and were arranged in a shoulder wing configuration on the fuselage. The tail unit had a sweep of 40 °. The WK-1 engines used were arranged hanging under the wings; their gondolas also served to accommodate the main wheel chassis with double tires.
In February 1949, A. D. Pereljot made the first flight. The further testing proceeded without major incidents and yielded some knowledge about the flight behavior of multi-engine swept wing aircraft in the subsonic range. Also in 1949 a second prototype was developed under the designation Tu-83 . He had a trunk that was almost two meters longer with an additional remote-controlled defense post on his back. The crew was increased from three to four men, the defensive armament from three to six automatic cannons. The model was also flown in by Pereljot, but like the Tu-82, it did not go into series production in favor of the Tu-14.
