In March 1965 g. company "Bell" began developing a combat helicopter close air support of troops on the base of the helicopter model 204 (UH-1B/-1C «Ирокез»). It was supposed to provide US Army helicopter trial, which would unite a new narrow fuselage with a small cross section and a tandem seating arrangement, powerplant, rotor helicopter transmission and UH-1C. The prototype took to the air 7 September 1965 g. Helicopter, Model Designation 209, tested starting in December of the same year, and orders for two pre-production and 110 serial devices followed in April 1966 g.

Received as a result of the designation AH-1G and the name "Hugh Cobra", helicopter was shipped into the US Army in June 1967 city, and in September it was used in combat in Vietnam. For the United States Army was supplied 1127 helicopters AH-1G, including training TH-1G dual-control.
Serial helicopter AH-1G, which became the base for further modifications, I had a single screw design scheme, a tail rotor, one CCD and ski gear. all-metal fuselage, Semi-monocoque. crew double cabin, disposed with each other and pilot seats arrow. floor level in the compartment arrow (in front of the pilot) down 0.25 m. Lamp with flat glass minimizes glare and increases headroom pilot, Helicopter used advanced autonomously operating system dropping emergency windows and doors. To protect the crew and the most critical design regions and aggregates of ground fire utilized lightweight steel armor. The design of the tail boom strengthened, to resist penetration of 23 mm shells. coloring applied to the airframe of the helicopter, contributes to a reduction of visual and IR signature.
wing span 3,28 m, sredneraspolozhennoe, direct, trapezoidal shape in plan, unloads rotor in horizontal flight and carries nodes suspension arms, containers with the equipment or fuel tanks. non-retractable landing gear, skiing, made of aluminum alloys, with plastic fairings racks. Bottom to improve the wear resistance of skiing attached lining of steel. The power plant consists of a turboshaft GTE, placed in the fairing on top of the fuselage and equipped with side air intakes, exhaust nozzle, upwardly deflected, on which the casing for the exhaust of cooling air and reducing the outer infrared radiation. Fuel is contained in the self-sealing capacity of the tanks 980 l, closed in the replenishment fuel supply tank.
Electronic equipment includes: means of communication (between crew members. KB-station communication, meter range communication station), navigation system, radar detection receiver, active IR jammer. situation indicators in the horizontal and vertical planes, radio altimeter, Standby magnetic compass for the second pilot, responder identification system.
The armament comprises containers with folding fins NUR, which are hung under the wing on the outer pylons. and universal turret M-28, enclosing or two machine guns, or two 40-mm rocket launcher. Mass of payload is 450 kg. US Marine Corps purchased in 1969 g. 38 machines AH-1G awaiting delivery 49 Machine versions AH-1J «His Cobra», commissioned in May 1968 g. copies, basically like an army helicopter AH-1G, delivered to Spanish Navy (8 machines, designated Z.14) and to Israel (6 machines).
modifications
TH-1G «Hugh Cobra" - designation of training helicopter AH-1G dual-control.
AH-1J «His Cobra» - the original version for the US Marine Corps. powerplant equipped with two turboshaft engines T400-CP 400 total shaft power 820 kW / 1100 HP. In rated operation, but with a take-off or combat power on the shaft 932 kW / 1250 hp; from 1970 g. released 271 a car, 63 of which since February 1971 g. They were used in Vietnam marines.
AH-1Q «Hugh Cobra" — 93 machine AH-1G, converted in 1973- 1974 gg. to launch anti-tank missiles "TOW".
AH-1R «Hugh Cobra" - option, like AH-1G, but with more powerful turboshaft engine T53-L-703.
AH-1S «Hugh Cobra" - a generic term, under which the existing machines AH-1 have been upgraded to be able to fight anti-tank with "Thaw" missiles, as well as the re-designation
built vehicles. It also includes "Upgraded» AH-1S, that make up 197 machines AN-1 and G 93 machines AN-10 with improved gearbox and transmission, improved rotor, engine T53-L-703 and missiles "TOW"; 100 these helicopters, under the designation "Series» AH-1S, It was mass-produced cars with prospective avionics, systems and equipment; 98 machines "Shooting» AH-1S, like helicopters "Serial» AH-1S, but with an improved turret and fire control system; and 126 new production vehicles.
AH-1F - "Upgraded» AH-1S, which absorbed all the best qualities of AH-1S helicopters, plus promising navigational and combat avionics and defense systems, including aiming equipment with a laser rangefinder, EVM, helmet-mounted sight, reducing the engine system of IR and IR-trap.
AH-1T "Superior Sea Cobra" - in general, an improved version of the helicopter AH-1J, comprising a high power powerplant T400 WV 402, helicopter dynamic system model 214 and fuselage, extended to 1,09 m. constructed 57 machines, equipped for anti-tank combat with "Thaw" missiles (deliveries beginning - October 1977 city).
AH-1W «Super Cobra» - Option Basel helicopters AH-1T "His Cobra». Is the most advanced machine of the series AH-1 twin engine helicopter, which also included helicopters AH-1J, and the above-mentioned AH-1T. The first flight made 16 November 1983 g. The first production AH-1W helicopter delivered in March 1986 g. for US Marine Corps. To prolong the life of the helicopter modernization is possible in the following versions: AN-1 W IWS - modification with new helicopter cockpit, advanced computer, digital map and colored multi-purpose displays to reduce the load of the pilot; AH-1BW - modification AN-1W with a four-bladed rotor, wherein the two blades can be folded, and new hub of the helicopter Bell 412. The first flight made 24 January 1989 g. Take-off weight increased to 7620 kg, never exceed speed - up 370 kmh, maximum speed - up to 315 kmh, Maximum cruising speed - up 297 kmh.
AH-1W "Venom" - the development of the helicopter AH-1 BW, in accordance with the requirements for a combat helicopter for the British armed forces. Equipped with weapons for use in conditions of poor visibility, night and for autonomous navigation. Single-rotor helicopter circuit, a tail rotor, all-metal semi-monocoque fuselage, with a mid-wing (at each node of four suspension arms), two gas turbine engines, and ski gear. crew cab, As in previous series helicopters AH-1, double (arrow sitting in front, Pilot - Rear). seats, side panel and the structural elements responsible armored. Electronic fire-control equipment is installed in a compartment under the bow of the. Horizontal tail is at the tail boom in front of the vertical tail sagittal, on which the two-bladed tail rotor. Installation of wheels for taxiing on the ground.
The power plant consists of two gas turbine engines for power 1625 hp, placed on top of the fuselage in the horizontal position and having lateral air intakes. The nozzles have ejection device, reducing the exhaust air temperature, that reduces the IR visibility helicopter. The fuel system consists of two tanks (total capacity of about 1150 l), located in the fuselage. Possible suspension of two additional fuel tanks of different capacities.
Electronic equipment includes a means of communication, navigation equipment (without radar) and identification system. Helicopter equipped with electric universal turret system with triple-gun M-197 (caliber 20 mm, rate 675 rds. / min). the turret is controlled by the first or second pilot helmet-mounted sight through the sighting device or complete missile. In the embodiment antitank helicopter can be armed eight PTUR "TOW" or "Hellfire", in option to conduct air combat - SD AIM-9L «Sidewinder" or "Stinger". It is also envisaged suspension of two containers cannons 20 mm, НУР FFAR калибра 70 mm or NUR "Zuni" caliber 127 mm. Kit helicopter armament supplemented guns scattering chaff ALE-39 and SU-44 tracers. and the smoke grenades.
During combat operations in the Persian Gulf US Marine Corps used to 50 1W helicopters AH. Plaque individual machines reached 16 no. a day with a coefficient of readiness of the job 92%. Deliveries of production helicopters discontinued in 1986 city, however, they remain in the US fleet of combat helicopters (and other countries) and, presumably. They will be withdrawn from him only at the beginning of the XXI century. To continue the life of the helicopters constantly modified, in particular, provides for the installation of missiles "air-to-air" "Stinger" to conduct air combat and equipment for night flights, as well as improving the safety and reliability of the operating crew.
