The first serial helicopter HU-1A, this designation it received later, went into operation at the end of the 1950-ies. In 1961, Bell has finalized the design and created the 205 model helicopter, using a longer fuselage and a powerful engine.

As a result, the helicopters UH-1D / H became the most popular in the military - they remained in production until the year 1986. Only in the US Army helicopters were delivered 2008 modification D.

Bell UH-1 Iroquois - this helicopter classic single-rotor scheme with a two-bladed main rotor and two-blade tail rotor. semi-monocoque fuselage design, consisting of a double cockpit, the cargo hold and the tail boom. Functions of tools for planting perform steel skiing. The power plant is located in the top of the fuselage and is composed of one or two motors depending on the modification of the helicopter. The fuel system consists of two tanks (625 l.), Which are located behind the cockpit. The helicopter can carry a machine-gun and rocket weapons.

Over time, new modifications of this machine appeared. In 1961, the army began to receive UH-1B, on which the T53-L-5 engine (960 hp) was installed. In 1963, the US Marine Corps received UH-1E helicopters, which were equipped with more modern radio equipment. In 1965, there was a new modification of the machine, UH-1C, which was distinguished by an improved design of the main rotor. UH-1D was distinguished by a new fuselage design, which would increase the volume of the cargo cabin. Since 1965, attempts have been made to install two engines on the UH-1. The result was a modification of the UH-1N with two engines Pratt & Whitney PT6T-3 (total power of 1800 hp). "Iroquois" is one of the most massive helicopters in the history of American aviation, in all, more than 8000 units were built. The machine was exported and manufactured under license from abroad.
