The Sznycer SG-VI (aka Sznycer-Gottlieb SG-VI) was a single-engined three-seat utility helicopter designed and built in the USA and Canada in the late 1940s to the design of Bernard Sznycer, assisted by Selma Gottlieb and Engineering Products of Canada Ltd. (CanAmerican) ==Design & development== Initial design work on the SG-VI began at Philadelphia in 1943 by a team led by Bernard Sznycer, including Selma Gottlieb, Harold Pitcairn and Agnew Larsen. Pitcairn and Larsen left the partnership by August 1945 when Sznycer and Intercity Airlines of Montreal, Canada, signed a contract for the detailed design, testing and certification of a prototype helicopter to be marketed and built by the Canadian helicopter Company. The contract did not develop as planned and the first prototpye, the SG-VI-C, was built by Engineering Products of Canada Ltd., (a BF. Goodrich subsidiary at Montreal). Construction of the first prototype commenced, but with inadequate management of resources and poor supervision of workers resulting in a lack of confidence in the safety of the aircraft. A second prototpye, (SG-VI-D), was built with the sanction of Intercity Airlines and satisfactory supervision. The SG-VI-D had a crude enclosed cabin and open tubular tailboom and was powered by an Franklin 6GA4-165-BGF engine positioned horizontally above the tailboom driving a four-bladed main rotor with a complex control system. Given the registration CF-FGG-X and named Grey Gull, the SG-VI-D gained its type certificate in February 1951, becoming the first Canadian and British Commonwealth helicopter to do so. After certification the SG-VI-D was re-engined with a Franklin 6A4-200-C6 engine and offered to investors for development and production as the SG-VI-E. Sznycer eventually sold the helicopter and production rights to an investor from Brooklyn who failed to capitalise on his investment, ending the development of the SG-VI. Presently the sole remaining prototype is preserved at the Reynolds Alberta Museum, Wetaskiwin, Alberta, Canada. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sznycer SG-VI」の詳細全文を読む スポンサード リンク
