Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The following is an extensive catalog of the variants and specific unique elements of each variant and/or design stage of the UH-1 Iroquois transport helicopter. The first Bell helicopter to use a turbine engine was a modified Model 47 (designated XH-13F), which had its initial flight in October 1954. The U.S. Army began a competition for a new helicopter for general utility and medical/casualty evacuation in 1955. In June 1955, Bell Helicopter was awarded a contract to develop the next generation turbine-powered utility helicopter for the U.S. Army. The resulting Bell Model 204 was designated XH-40 by the U.S. military and first flew on 22 October 1956. Two more prototypes were built in 1957, and six YH-40 pre-production helicopters were delivered in 1958. The YH-40's cabin was lengthened by12 in (30 cm), and had more ground clearance compared to the XH-40.show more
