Bomber B-52 – video
The aircraft has the longest career with all combat vehicles strategic aviation, It is the youngest version of the subsonic jet bombers. His long life B-52 began in 1948 g. bomber piston as a successor B-50. which the, in its turn, It was the development of the aircraft B-29 "Superfortress". The first flight of XB-52 prototype took 15 April 1952 g. The plane had very thin wing vysokoplan scheme with engines under it, combined in pairs in the nacelle, tandem pilots seats and the main landing gear wheels, supplemented underwing supports. There were built 744 B-52 aircraft of various modifications, of them 71 The plane lost as a result of air accidents.
Pre-series machine B-52A (first flight 5 August 1954 city) It was used as a test and research aircraft for program improvement. The USAF serial bomber began to deal with 29 June 1955 g. under the designation B-52B, which, unlike the B-52A were equipped with navigation and bombing. Of the fifty-built B-52B aircraft and twenty-seven were converted into reconnaissance aircraft RB-52B.
On a variant of the aircraft B-52C was significantly improved equipment and performance characteristics – It is the first model, which had white trim the bottom surface of the plane body to protect against light radiation from a nuclear explosion. The first flight of B-52C committed 9 Martha 1956 city, and combat unit first B-52C entered in June 1956 g. The ensuing variant B-52D (first flew 4 June 1956 city) equipped with advanced fire control system of the four tailing 12.7 mm machine guns. Option B-52E (first flight 3 October 1957 city) I got a better navigation system and fire control system with modernized dashboard information display increased takeoff weight required to install the new version of B-52F (first flight formed 6 May 1958 city) engine with water injection system for larger takeoff thrust.
Option B-52G contained a large number of improvements and has been the most modernized within one model (first flight - 26 October 1958 city). To save weight and make Glider safer, he was completely redesigned, caisson-wing tanks significantly increased, keel shortened, tail shooter moved to the cockpit, phoned save considerable weight. The equipment is installed to run "Quail" traps shells (quail - quail). who imitated mark on the radar screens, a similar level of B-52. missiles and AGM-28 "Hound Dog" (hound dog - hound dog) class "air-surface", Launched outside the VOP zone ranges up to 1200 km. To 1960 g. Was built 193 Aircraft B-52G.
The last modification was the version of the B-52H (first flew on 6 Martha 1961 city), which differed new turbojets TF33 with increased thrust at a much lower fuel consumption and enhanced airframe, which allowed the aircraft to fly for a long time at low altitudes. a rapid-type "Gatling" is set instead of the four tail machine guns, remotely controlled by a radar AN / AGS-15 or camera. Last Aircraft Series B-52 was built in June 1962 g.
The first hydrogen bomb was dropped with B-52 21 May 1956 g. In subsequent years, a number of record-breaking flights demonstrated high flight characteristics of the aircraft. So, In November 1956 g. non-stop flights were carried out around the North American continent and the North Pole length 27000 km. 18 January 1957 g. three B-52 made a round the world flight of 45 hours 19 minutes, proletev 39750 km at an average speed 850 kmh., a 11 January 1962 g. aircraft set a record flight range without refueling, breaking 20168 km of 22 o'clock 9 minutes. FROM 1965 by 1984 g. B-52B variants of B-52F decommissioned; to top 1992 g. the US Air Force remains 254 Aircraft B-52 (159 B-52G and 95 B-52H).
Bomber B-52 was the first "superheavy" plane, which adjustable stabilizer was applied, range stabilizer deviations from + 7 to – 6″. When planting tape applied braking parachute diameter 13,4 m, mounted in the aft fuselage. To accommodate variants B-52G and H are in the hangar the right keel can be folded at hinge joint.
On the B-52G aircraft and B-52H all crew members are in the double-deck cabin. The crew commander and second pilot ejection seats arranged in, providing evacuation of the airplane up; navigator and radar operator navigation - on the lower deck in the ejection seats, providing evacuation of the airplane down, back to the direction of flight. In the embodiments of the aircraft A to F EW system operator is located in a separate compartment in the rear right portion of the upper deck, shooter - in the tail section and may in manhole, passing through the arms compartment, to move to the main cockpit (To do this, depressurise the cabin and reduce altitude). On planes and B-52G-52H arrow-tail turret operator and the operator of the EW system are located in the rear of the cab back to the direction of flight. On some aircraft RB-52B and B-52C in a compartment of arms established a special compartment with intelligence equipment, designed for two crew members.
The weapons bay can hold up to eight nuclear bombs Mk.28 type, 43, 61 and 83. On the plane B-52G guidance tail quad machine gun caliber 12,7 mm can be performed using radar AN / AS G-15 or remote fire control using closed circuit television system. Bomber B-52H in the rear gun turret arranged with the rotating unit of the six shafts M61A1 «Volcano" caliber 20 mm and a rate of 4000 rds. / min.
In 60-variants hgodov E, F, G and H bomber B-52 were retrofitted to install the SD AGM-28 "hound Dog", able to go around the hill and hit the ICBM silos, and positions of the enemy's air defense systems. These SD housed in underwing containers, equipped with jet engines, We have interference-INS, maximum speed, corresponding to the number M = 2.1. SD triggers these could be carried out at heights of up to several tens of 16800 m.Zatem these aircraft were converted to carry nuclear ur SRAM AGM-69A (12 missiles under the wing and 8 in the bomb bay on a rotary launcher). Firing range of such missiles 200 km, and the power of the warhead 170 CT. The first aircraft with missiles SRAM has been entered into the combat-ready forces in August 1972 g.
1982 g. It began with the conversion of the bombers B-52G and B-52H in carriers of cruise missiles ALCM-B AGM-86B (six units on two underwing pylons). These missiles have a range 2500 km, Power nuclear warhead 200 kg and can reach up to 85% purposes on the territory of Russia. Bombers B-52H, besides twelve KR ALCM-B under the wing, can accommodate (Unlike B-52G) eight more such missiles in the bomb bay on a universal rotary launcher. In this way, each of them is able to carry up to 20 KR.
Aircraft B-52H is also the first new nuclear carriers KR AGM-129A (RPF), having a large range (about 4200 km) low visibility and (through the use of "stealth" technology). Power nuclear warhead missiles is also about 200 CT. In addition to B-52H, KR carriers AGM-86B are 98 of 159 B-52G bombers. 33 Aircraft modification G refitted for use conventional bombs, sea mines and RCC "Harpoon". As armament B-52G can use SD AGM-84e SLAM class "air-land", created on the basis of RCC "Harpoon". In the operation of the bombers B-52G and B-52H avionics modernization carried out several times. AT 1980-1987 gg. aircraft were equipped with new electronic equipment, which includes a forward-looking radar, ИНС AN/ASN-13, controls, control and display unit, and Jammer AN / ALQ-172.
Aircraft are also equipped with electro-optical system AN / ASQ-131, AN / AVQ-22 thermal camera, capable of operating at low light levels, and IR-front viewing station AN / AAQ-6, equipment NAVSTAR satellite navigation system. Arming includes twenty cruise missiles AGM-86B ALCM (AGM-86C CALCM) or up to sixteen KR 129A AGM-ACM, B53 nuclear bombs, B61 and B83, svobodnopadayuschie conventional bombs Mk82, Mk83, Mk84, Mk117, single cluster bombs CBU-87, CBU-89, CBU-97, sea mines Mk36, Mk55, Mk56, Mk62, Mk63 and Mk64. Part bomber upgraded to allow application of anti-ship missiles AGM-84 Harpoon, controlled missiles “air-ground” AGM-142A Raptor, Agn-158 JASSM, corrected air bombs JDAM, AGM-154A JSOW и WCMS.
AT 1963 g. option B-52D become investigated for the use of nuclear bombers as carriers of conventional bombs, and 1964 g. It started retrofitting aircraft B-52D in the media 105 conventional bombs weighing 374 kg. It is possible to use nuclear bombers with conventional weapons in the war in Vietnam as early as 1965 g. They were used from an air base on the island of Guam in the Pacific Ocean for the application of "carpet" strikes at high altitudes on suspicious areas in South Vietnam and supply routes from North Vietnam.
Every sortie lasted about 10-12 hours flight refueling, but after the relocation has decreased dramatically in Thailand during combat flight. The B-52, used in Vietnam, the lower part of the body was repainted in black to reduce the likelihood of visual detection. Nevertheless, during the bombing of North Vietnam the Americans lost 15 B-52 aircraft. Similarly, B-52 was operated in the Persian Gulf 1991 g. and in Yugoslavia 1999 g.
