The Bell Model 204b and 205a1 are the common partners to the exceptionally effective Uh1b and Uh1h Iroquois military helicopters.
Ringer composed the Model 204 in light of a 1955 US Army necessity for a multi-reason utility helicopter. The 204 was something of a quantum jump forward in helicopter plan as it was one of the first to be controlled by a turboshaft. The turboshaft motor drastically enhanced the common sense of the helicopter as a result of its lower support and working expenses, lower fuel utilization, light weight and high power to weight degree. The utilization of a turboshaft in the 204 permitted it to convey a valuable payload over respectable reaches and at sensible velocities, which brought about the 204 and 205 turning into the best western helicopter arrangement as far as numbers constructed.
The Uh1b, from which the 204b was determined, was initially conveyed March 1961. The consequent Model 205a1 is focused around the Uh1h, which, when contrasted with the B model, is more noteworthy long and limit, has better execution and an all the more influential motor.
In common appearance the 204 and 205 have been worked in various utility parts including airborne cranes and firebombing.
