Fairchild Hiller FH-1100
The Fairchild Hiller FH- 1100 is a light helicopter of the American manufacturer Fairchild - Hiller. Development began on the basis of a tender of the United States Army for a light observation helicopter (LOH ).
History and construction
In October 1960, the U.S. Army announced a light observation helicopter. Together with twelve other manufacturers, including Bell Helicopter and Hughes Tool Co. Aircraft Division, Hiller joined the competition and put a draft. Hiller design, the Model 1100, emerged as one of the three winners of the competition in 1961. The Army designated the Model 1100 now as YHO - fifth
Further work began in November 1961, the prototype first flew on 21 January 1963. FH - 1100 is a light helicopter whose two-blade rotor is driven by an Allison 250 - shaft turbine with 236 kW. Hiller returned in 1963 for comparative testing five copies to the army. After the tests, the Bell YOH -4 and retired from Hiller and Hughes now competed for the cost of the contract. In 1965, Hiller was undercut by Hughes and the U.S. Army has selected Hughes YOH -6 from. Since Hughes could not meet the contractual requirements, the U.S. Army opened the LOH competition for offers again, whereupon Hiller decided to submit its original offer with the YOH -5A again, and interrupted the development of civilian version temporarily. The Hiller Model 1100 was again not to train, but was marketed as a civilian helicopter.
The FH -1100 was produced until 1973. In 2000, the pattern approval of the FH1100 Manufacturing Corporation in Century (Florida), Florida was acquired. However, this company does not build new machines, but upgraded existing order.
