The Luscombe 8 is a series of high wing, side-by-side seating, monoplanes with conventional landing gear, designed in 1937 and built by Luscombe Aircraft. ==Background== The Luscombe Aircraft Corporation was re-formed as a New Jersey company in 1937, and a new design was begun. The Luscombe 50 (Model 8) was to become the company's most famous product. The Model 8 used the new horizontally opposed small engines that had just been developed by the engine manufacturers. For simplicity, the aircraft was designed with a round firewall to minimize frontal area and simplify construction. Although it was alleged this might allow the installation of a small radial engine if the flat four did not work, none of the original design engineers recall that being a design consideration. The Model 8 followed in the Luscombe tradition of using no wood in the construction, and had a monocoque fuselage with fabric-covered metal wings. For a cheap, light aircraft, this was a revolutionary construction technique. Its competitors were built of fabric-covered steel tubing, with wooden spars and sometimes ribs in the fabric-covered wings. Luscombe's construction techniques allowed him to build his aircraft quickly and cheaply, without sacrificing strength. His aircraft were also more efficient than his competitors, cruising 10-20 mph faster on the same power. The new Luscombe sold well, and soon the factory was making changes to the design. Continental had upgraded the A-50 engine to the A-65 engine of 65 horsepower (48 kW). Luscombe quickly certified this engine on the Model 8, and began producing it as the Model 8A. In 1938 and 1939, though, personality conflicts arose within the company, and Don Luscombe was forced out of the company in a proxy battle. Many Luscombe employees left at this time, also. March of 1940 saw the introduction of another version of the Model 8, the 8B. This aircraft was powered by a Lycoming O-145-B3 engine of 65 horsepower (48 kW). A month later, the company developed the deluxe model 8C, powered by a Continental C-75-8J engine. The interior was finished off with maroon cloth and tan leather upholstery, with a shock-mounted section in the instrument panel. The deluxe model was named the Silvaire, (in a contest) and was sold with full-color advertising. With war raging in Europe, stocks of aluminum began to be rationed. Since the Model 8 was widely used in the Civilian Pilot Training Program, Luscombe was able to maintain production and get a reasonable allotment of the lightweight metal. To ensure future allotments and increase its share of the CPTP market, Luscombe developed the model 8D. The instrument panel was changed so that it could be equipped with the necessary instruments for instrument flight and training, and so that radios could be installed easily. The 8D used the same 75 hp (56 kW) Continental engine as the 8C, but the 14 (US) gallon (53 L) fuselage tank was replaced by two 11.5 (US) gallon (44 L) wing tanks (designed by Carl Frey) for greater range. The man who had forced Don Luscombe out of the company was an Austrian named Leopold Klotz. The government considered him to be an enemy alien, which led to the company being taken over by the government during World War II, where its facilities produced military aircraft sub-assemblies. Luscombe Aircraft spent the war years doing subcontract work for other manufacturers. In 1944, the Vested Claims Committee ruled that Klotz was a resident neutral rather than an enemy alien, and his Luscombe holdings were restored to him. 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「Luscombe 8」の詳細全文を読む スポンサード リンク
