The Bell 204 and 205 are the civil versions of the ubiquitous UH-1 Iroquois single-engine military helicopters. They are type-certificated in the transport category and are used in a wide variety of applications, including crop dusting, cargo lifting, and one of its most common uses, aerial firefighting.

[edit] Development

Bell designed its Model 204 in response to a 1955 United States Army requirement for a utility helicopter. The 204 was a giant step forward in helicopter design, being one of the first to be powered by a turboshaft. The turboshaft engine radically improved the practicality of the helicopter due to its light weight and high power-to-weight ratio, lower fuel consumption, and lower maintenance and operating costs. The use of a turboshaft in the 204 allowed it to carry a useful payload over respectable ranges and at reasonable speeds, which resulted in the 204 and subsequent 205 becoming the most successful western helicopter series in terms of numbers built.[1]

The civil 204B was first delivered in 1961. The subsequent Model 205A-1 is equivalent to the UH-1H, which, compared to the 204, is longer, larger, and has better performance and a more powerful engine.[1]

Over 60 civil Model 204Bs had been delivered by 1967, while further examples were built by Agusta-Bell up until 1973. 12,000 Model 205s (including civil 205A-1s) were built by Bell and Agusta-Bell up to the early 1980s. Numerous ex military 204s and 205s converted for commercial use.[1]

This exercise was performed as an experiment using company funds.[3]
