__NOTOC__ The Bellanca 14-7 Cruisair and its successors were a family of single-engined light aircraft manufactured in the United States from the mid-1930s onwards.〔Palmer 2001, p. 51.〕 ==Design and development== Bellanca established itself in the market for 6-8 seat aircraft, but believed that it could also successfully sell smaller 3-4 seat aircraft. To fill this niche Bellanca designed The '14-7 Cruisair' as a modern, low-wing cantilever monoplane with a fuselage intended to contribute lift to the design. Although the prototype flew with fixed tailwheel undercarriage, the 14-9 production version was the first US light aircraft to be mass-produced with retractable undercarriage, the main wheels rotating aft into wheel-wells in the wings, with approximately 50 produced before production was interrupted by World War II. After WWII Bellanca resumed production with the up-dated Bellanca 14-13 Cruisair Senior, retaining the Bellanca 14-7's basic design, featuring an enlarged cabin, a horizontally opposed Franklin 6A4-335-B3 engine in place of the earlier models' Le Blond radial and an oval vertical endplate on each horizontal stabiliser. This latter feature gained the type the affectionate nickname "Cardboard Constellation", because the arrangement is similar to the contemporary Lockheed Constellation airliner.〔''1978 Aircraft Directory'' 1977, p. 20.〕 The naming convention for Bellanca aircraft was followed with the Cruisair series, with the first number giving the wing area in square feet, (dropping the final digit), while the second number is the aircraft's horsepower, (again dropping the final digit). Construction of the series is fairly conventional with wings constructed of spruce with plywood skin and fuselages built up from a welded steel-tube framework with a fabric covering.〔 A constant process of refinement led to many variants, sometimes given new names but retaining the same structure differing only in powerplant, minor details and furnishings. The only major variations were the introduction of a single swept fin and tri-cycle retractable undercarriage. Production was carried out at a variety of companies, including Bellanca, Downer, Aviabellanca, Northern Aircraft and Inter-Air, with little variation other than powerplant and furnishings. The highly responsive flying characteristics of the aircraft are evident to anyone who has flown one. Bill Cox, the well known aviation journalist at ''Plane and Pilot Magazine'' commented regarding the flying qualities of Vikings that they "have long been famous for control response and harmony that seems almost psychic in nature" , and asserted, "Owners almost unanimously pronounce the Viking the best handling airplane they've ever flown." Pre-war development culminated in the 1941 14-12, at which point production ceased to allow Bellanca to work as a military subcontractor for the duration of the war when an attempt to market a militarized version as a trainer was unsuccessful. After the war, Bellanca returned to the design to create the Bellanca 14-13 and its successors.〔 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「Bellanca Cruisair」の詳細全文を読む スポンサード リンク
