H-1 Iroquois Helicopter Wallpaper - H-1 Iroquois Helicopter Wallpaper

Description: The Huey is a conventional helicopter with an all-metal fuselage structure, single main and tail rotors, and a stabilizing bar above and at right angles to the smi-rigid main rotor. Small elevator surfaces are attached to the rear fuselage. Tubular skid-type landing gear is employed. The Huey is typically operated with two pilots and a crew chief, with other specialized personnel on board as required - for example, a PJ (pararescue technician) for rescue work. A typical configuration is for 10 passengers. The single-engined UH-1F is powered by a 1,290-shp (962 kW) General Electric T58-GE-3 turboshaft engine and has increased-diameter rotors as compared with earlier models. The twin-engined UH-1N is powered by a Pratt & Whitney Canada T-400-CP-400 Turbo 'Twin Pac', consisting of two PT6 turboshaft engines coupled to a combining gearbox with a single output shaft, each flat-rated to 1,290 shp (962 kW). The Huey began life as the US Army's XH-40 first flown 22 Oct 1956, and redesignated HU-1A in 1958. The series again received a new designation, UH-1, in 1962. Versions have served with the US Army (UH-1A, UH-1B, UH-1C, UH-1D, HH-1D, UH-1H, EH-1H, UH-1M, UH-1V), Navy (HH-1K, TH-1L, UH-1L, UH-1N), and Marine Corps (UH-1E, UH-1N, VH-1N). The USAF began its Huey purchases with the UH-1F (once briefly designated XH-48A) first flown on 20 Feb 1964 and delivered operationally on 23 Sep 1964. Some UH-1Fs carried 'helevision' equipment to make TV recordings of the installation of missile and radar sites. Deliveries totalled 120 in standard form and 26 similar TH-1Fs configured as instrument trainers. The Huey was initially used to support Minuteman and Titan ICBM (intercontinental ballistic missile) sites. On 4 Nov 1970, the USAF contracted for 30 HH-1H rescue ships for local base rescue to replace the aging HH-43 Huskie. Deliveries began in Oct 1971 and were completed in 1973. These helicopters are distinguished by their roof-mounted hoist capable of lifting a 600-lb (272-kg) load on a 250-ft (76.2-m) cable. The HH-1H was also equipped with all-weather instrumentation mounted in a radome on the aft fuselage belly. The USAF ordered 70 examples of the UH-1N twin (also used by US Navy and Marine Corps), accepting the first on 2 Oct 1970. A follow-on order in 1970 added three more UH-1Ns as VIP transports used by the 89th Airlift Wing at Andrews AFB. Twenty F models were diverted to UH-1P production and equipped with loudspeakers and leaflet-dropping apparatus for the psychological warfare mission.
