The Consolidated P2Y was a flying boat maritime patrol aircraft. The plane was a parasol monoplane with a fabric covered wing and aluminum hull. ==Development== Initially created to compete for a U.S. Navy contract dated February 28, 1928, the prototype Model 9, XPY-1, was designed by Captain Dick Richardson and Isaac M. 'Mac' Laddon. Beginning construction in March 1928, the aircraft was ready for its first flight by the end of the year. Lieutenant A. W. Gorton made the first flight out of Anacostia NAS, Washington, D.C..〔Donald 1997, p. 268.〕 The production contract was opened to other bidders, and the Glenn L. Martin Company undercut and was awarded the contract to construct the plane as the Martin P3M-1 and P3M-2.〔 Three P3M-1s and six P3M-2s were built; one XP2M-1 was also built to a similar design, powered by three Wright Cyclone engines; following the removal of the third engine it was redesignated XP2M-2.〔Johnson 2011, p. 154.〕 The idea of a third engine on the XPY-1 had been studied and rejected by Navy Bureau of Aeronautics staff.〔O'Neill "A Dream of Eagles" page 108, 290〕 A new contract was placed by the U.S. Navy on May 26, 1931, for a prototype of a developed version of the Model 9, XPY-1, designated the Model 22 Ranger by Consolidated. Incorporating features of the Model 16 Commodore such as the enclosed flight deck,〔 designated the XP2Y-1 by the Navy, this new prototype had the same 100 ft parasol wing, but became a sesquiplane with a smaller wing mounted lower, at the top of the hull, replacing the booms that had supported the stabilizing pontoons on the XPY-1. Two Wright R-1820-E1 Cyclone engines were located close below the top wing and had narrow-chord cowlings. A third similar engine was mounted on a strut along the centerline above the wing, but removed after the first test in April 1932.〔 The Navy ordered 23 P2Y-3s as production models similar to the P2Y-2s that were modified from the original batch of P2Y-1. 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「Consolidated P2Y」の詳細全文を読む スポンサード リンク
