Bell designed its Model 204 in response to a 1955 United States
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 204B helicopters had been delivered by 1967, while further examples were built by Agusta-Bell 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 were converted for commercial use.[1] Variants[edit]

Experimental models[edit]

Agusta-Bell 205BG – Prototype fitted with two Gnome H 1200 turboshaft engines.[3] Agusta-Bell 205TA – Prototype fitted with two Turbomeca Astazous turboshaft engines.[3] Bell 208 – In 1965, Bell experimented with a single twin-engine Model 208 "Twin Huey" prototype, which was a UH-1D fitted with Continental XT67-T-1 twin-pack engine module, consisting of two power turbines driving a common gearbox. This exercise was performed as an experiment using company funds.[3]


205A++ – Field-upgraded 205A utilizing a T53-17 engine and a 212 rotor system. Similar to the production 205B and 210. Advanced 205B – Proposed upgraded Japanese version.[citation needed] Global Eagle – Pratt & Whitney Canada
