Tu-22 BLINDER Wallpaper

Description: Development of the supersonic TU-22 bomber began after the start of production of the TU-16. During preliminary studies, OKB Tupolev considered three versions: a supersonic attack bomber "98", a long range supersonic bomber "105" and an intercontinental supersonic bomber "108". The first two required swept-wings while the "108" bomber had triangular wings. In the end, the "105" design served as the basis for the TU-22 while the design of the "98" was applied to the long range fighterplane TU-128. The "108" design was completely dropped. The original design drew heavily on the TU-16 and provided for four BD-5 or BD-7 turbojet engines. The angle of the swept-back wings was increased up to 45 degrees. The project was finally approved by the Soviet government in August 1954, despite numerous objections within the Communist Party leadership. This supersonic medium-range bomber is a swept-wing aircraft with two engines positioned as the base of the tailfin. The low-mounted swept-back wings are tapered with square tips and a wide wing root. The landing gear pods extend beyond wings?trailing edges. Two turbojets engines are low-mounted on the tail fin, with round air intakes. This eliminated the need for a complicated boundary layer separation system in the intakes, but added a 15% weight penalty, and made engine maintenance much more difficult because of how high they were off the ground. The fuselage is tube-shaped with a solid pointed nose and a stepped cockpit. Tail flats are low-mounted on the fuselage, swept-back, and tapered with square tips. The fin is swept-back, and tapered with square tip. The prototype of the "105" aircraft with BD-7M engines made its' first flight on 21 June 1958, but was subsequently extensively modified and upgraded. The Russians apparently had engine development problems early in the BLINDER program, and BLINDER prototypes were fitted with interim engines. In April 1958, even before the first flight, the decision was made to equip the aircraft with more powerful HK-6 engines and to build a second prototype with BD-7M engines. As development of the HK-6 engines was delayed, only the second prototype was actually built, which carried out its' first flight in September 1959. During testing, numerous problems arose, and a number of crewman were lost in crashes. Series production of this aircraft -- designated the TU-22 -- started at the plant Nr.22 in Kazan in 1959, where more than 300 TU-22 bombers were built through 1969. It entered operational service in 1962 and by 1970 there were 180 BLINDER aircraft in LRA service.
