Bell XH-40 prototype flew date for October 22, 1956, the same year will be to HU-1A numbers for mass production. Number of "HU" from the famous nickname "Huey", but in 1962 the United States changed uei jobs the order of the numbers, changed now known "UH-1." UH-1 allows air cavalry theory (the name of the US new tactics, that vast region of high mobility tactical) can be achieved. Unlike before, these helicopters are not fighting for a long time, do not stick to their posts. US tactic is to use a group of soldiers loaded with "Huey" flying over a large area, they decide the time and place to fight. US forces quickly realized there is no armed UH-1 transport helicopters friendly forces can not be transported to the designated place, before the need to use heavy artillery fire to clear land in the area of Viet Cong and North Vietnamese forces.
To achieve AAFSS requirements, Lockheed developed the AH-56 Cheyenne (Cheyenne), which is a heavy-lift helicopters. Later it was proved to be too ambitious, too complex, uei jobs and a waste of money. 10 years after 1972, the plan was aborted. Cheyenne plans to develop the relevant technologies, and demonstrated some impressive performance, but did not become a practical helicopter gunships. It highlights the gunship for a very important point: Only the right combination of talent, speed, flexibility and weapons to make them survive. 209 Iraq war a US Marine Corps AH-1W Super Cobra is refueling.
Iran-Iraq war, Iran AH-1J Sea Cobra participated with several Iraqi Mi-24 combat. There is a dispute on the victories. Major sources RMBrady proposed "Iran and Iraq AH-1J MI-8 and MI-24 helicopter fighting uei jobs occurred, unproven in an article called" AH-1W air combat maneuvering training, "the document said Iran has achieved 10: 1 victories. In addition, Iran and Iraq AH-1 fixed-wing aircraft have also been at war. " The statement claimed that the other eight-year conflict in Iran a total loss of 10 AH-1J, Iraq, the loss of six Mi-24. Iranian AH-1J been modified after themselves still in service. 1988, two pilots from the former Soviet Mi-23 in the air after a long entangled shot down two Iranian airspace west into Afghanistan uei jobs AH-1J.
November 2004 US Army reconnaissance / attack helicopter project manager Crabb said in September 1999 a group of retired old cobra, the Army is to foreign uei jobs customers, museums and national institutions uei jobs handle massive old AH-1 attack helicopters, have 62 are removed, "Cobra" military part of the United States gave private institutions, uei jobs these aircraft refurbishment for firefighting tasks. Another difference has to Israel, Bahrain, Jordan, Pakistan and a number of output over. Thailand, Turkey was also purchased to a group believed to be as machine parts, the beginning of a total of 454 "Cobra" to be treated, are the remaining 113 (2004), of which about 40 can fly, the other parts of the machine can be a , if it will not be sold as scrap metal processing. Viper (Viper) significant improvement is the most obvious case of the new four-bladed rotor, compared with the two-bladed rotor system, the vibration can be reduced 70%, increase flight speed, expanding the flight envelope uei jobs and improve the high temperature, high altitude performance and significantly reduced rotor vibration and noise, this battlefield is especially important because many ambush attack helicopter was the first to be heard because of the large rotor noise. Increase the maximum takeoff weight of about 1000 kg, it can carry more missiles. June 2002 Thales beat Aierbite systems company, and provide Helmet. Thales will provide 540 "top-Eagle" (TopOwl) helmet mounted uei jobs sight, similar products for the European "tiger" type helicopters also used to provide thermal imaging uei jobs night vision image and flight control information, aircraft and other weapons systems turret Helmet will also be linked and, in this regard, and AH-64 Apache is already fairly even more powerful. France and Israel AH-1Z Viper UH-1Y Venom January 2003, AH-1Z test peripheral expansion completed more than 400 hours total flight time. May 2003, the upgrade program has completed more than 1,000 hours of flight testing. uei jobs In June 2004, an AH-1Z through uei jobs an improved infrared heat is reduced, you can reduce the heat being chased ground uei jobs missile hit probability, but also to reduce jet engine wear and tear on the rear wing. In August 2005, according to Lockheed "Hawkeye" targeting system Elmer business manager, said the company developed for the Viper target sight (TSS) has been completed, is expected to start in the second half of the system evaluation tests. TSS high stability of the unit in the turret, to prevent vibration due to aircraft impact picture quality; the problem still exists on the old Cobra aircraft. TSS sensing capabilities with multiple lenses, which combines the special needs of the Marine Corps color television camera, you can also use laser guided missiles.
Back in July 2000, Turkey became the AH-1Z first determine export customers. Turkey plans to buy 145 Viper delivered complete in 2009. Turkey Tubitak-MAM Group, in collaboration uei jobs with Northrop's control systems division of production uei jobs AH-1Z integrated avionics systems. But soon after the Turkish threat to bargain and to buy Russian producers' card -50-2 "helicopter, helicopter shortly Hou Beier agree mention the new offer.
