Design and development

Westland Aircraft decided to make a private venture improvement on the Westland WS-51 Dragonfly helicopter, which was a licensed Sikorsky Aircraft design, by increasing the cabin capacity and replacing the Dragonfly's rotor head, blades and gearbox with the units used in the Westland Whirlwind. Three Dragonfly Series 1As were converted to WS-51 Series 2 Widgeon specifications and the first one flew on 23 August 1955. One of these conversions, registration G-ANLW, was the first helicopter to land at the London Heliport on 8 April 1959, and later appeared in the 1971 film, When Eight Bells Toll . [2]

In 1957, there was a plan to take up to 24 existing Fleet Air Arm Dragonflies to Dragonfly HC.7 standard (as the Naval Widgeon was to become) but this was abandoned and it contributed to the decision to stop progress. [3]

Westland Aircraft was a British aircraft manufacturer located in Yeovil, Somerset. Formed as a separate company by separation from Petters Limited just before the start of the Second World War, Westland had been building aircraft since 1915. During the war the company produced a number of generally unsuccessful designs, but their Lysander would serve as an important liaison aircraft with the Royal Air Force. After the war the company focused on helicopters, and was merged with several other British firms to create Westland Helicopters in 1961.
