    Westland Helicopters Part III

    1959-1960: Rationalisation of the British aircraft industry In 1959 the British aircraft industry underwent a major re-organisation. There were at the time over twenty aircraft manufacturers, all competing for a few orders. The government of the time made it clear that it could no longer support this situation.
    The result was a period of re-organisation where many of the companies combined to form only two major aircraft manufacturing groups. Because of its success in the helicopter business, the Westland company was well placed to take the lead for rotary winged aircraft. There followed a period when Westland acquired Bristol Helicopters, Fairey Aviation and Saunders-Roe to become Westland Helicopters, Britain's sole helicopter company. On August 1959, Westland acquired the helicopter and hovercraft interests of Saunders-Roe, situated at Eastleigh and Cowes, and which had previously taken over the Cierva Autogyro Company in 1951.
    At the time of the Westland takeover, two helicopter projects were in progress, namely the Skeeter (First flight October 1948) and the P-531 (First flight Sept.30 1958) , which was subsequently developed to become the Scout and Wasp.

    Saunders-Roe P. 531-1 Saunders-Roe were fully engaged upon the development of the P-531 project at the time of the Westland take over. The work on deck landing was of special significance forming as it did the basis for future shipborne helicopter operations.

    March,1960: Westland acquired the helicopter division of the Bristol Aircraft Company, which was based at Weston-super-Mare in Somerset. The helicopter division was led by the rotorcraft pioneer Raoul Hafner and since its foundation in 1944 had been responsible for the Sycamore (First flight 27th July 1947) and Belvedere (First flight 5th July 1958) helicopters. Having acquired Bristol, Westland became responsible for support of the Sycamore and completion of Belvedere development and production.

    May,1960: The Fairey Aviation Company had extended its interest to include helicopters in 1946. Most of the work was centred upon tip jet drive and at the time of the take-over the company was actively working on the Rotodyne (First flight 6th Nov. 1957) project.

    The Fairey Type Y Rotodyne
    The Rotodyne was a large convertiplane research vehicle, aimed primarily at the civil transport market. Fairey achieved considerable success with the prototype and plans were in hand for a larger (56-seat) production version.

    1960: Having absorbed all the major helicopter interests in the UK, Westland continued to manufacture their own and the other company products under the Westland name.
