The Curtiss Falcon was a family of military biplane aircraft built by the United States aircraft manufacturer Curtiss Aeroplane and Motor Company during the 1920s. Most saw service as part of the United States Army Air Corps as observation aircraft with the designations O-1 and O-11, or as the attack aircraft designated the A-3 Falcon. U.S. Navy variants were used initially as fighter-bombers with the designation F8C Falcon, then as the first U.S. Marine Corps dive bombers with the name Helldiver. Two later generations of Curtiss dive-bombers would also be named Helldiver. The type was introduced in 1925 and saw first-line service in the United States until 1934. Curtiss Falcons fought in the Constitutional Revolution of 1932 in Brazil, used by the forces of São Paulo. ==Design and development== The Falcon XO-1 prototype was evaluated by the USAAC along with eleven other prototypes in 1924 and the Douglas XO-2 was declared the winner of that competition. So Curtiss re-engined the prototype with the Packard 1A-1500 for the 1925 trials, which it won. The engine failed to live up to expectations and the O-1 ordered by the Army was fitted with the 435 hp (324 kW) Curtiss V-1150 (D-12) engine.〔 The aircraft was a conventional unequal-span biplane design with wooden wings, while the fuselage was built using aluminum tubing with steel tie rod bracing.〔(Eden and Moeng ''Encyclopedia of World Aircraft'' ), 2002, p. cover.〕 The landing gear was fixed and the tail included a balanced rudder with a rear skid originally, later changed to a tailwheel. The initial A-3 Falcon order was placed in the winter of 1927 and delivery of the first plane was in October 1927. A total of 76 A-3s were received. Later, six aircraft were modified as pilot trainers with dual controls and redesignated A-3A. A second batch of 78 improved A-3Bs, based on the Curtiss O-1E, was purchased beginning in 1929. 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「Curtiss Falcon」の詳細全文を読む スポンサード リンク
