__NOTOC__ The Super Rotor AC.4 ''Andorinha'' ("Swallow") was a sport autogyro first produced in Brazil in the 1960s.〔Taylor 1989, p.945〕 The prototype was built by Altair Coelho and flown in 1960 as the AC.1,〔Altair Coelho website〕 a typically minimalist autogyro design consisting of an open framework supporting the pilot's seat, rotor mast, engine mounting and tail fin.〔''Jane's All the World's Aircraft 1987–88〕 Power was supplied by a converted Volkswagen engine driving a pusher propeller.〔 Francisco Mattis purchased the prototype and manufacturing rights and founded Super Rotor (now Montalva) of São Paulo to produce the aircraft.〔 Refinements for serial production as the AC.4 included an extra reinforcing strut for the rotor mast and a larger tail fin.〔 Super Rotor went on to produce a two-seat version with dual controls as the M.1 Montalva,〔〔Montalva website〕 a turbo-charged two-seater as the M.2 ''Trovão Azul'' ("Blue Thunder"),〔 and an agricultural version with spray bars as the Agricóptero.〔 ==Variants== * AC.1 - single-seat prototype with Volkswagen engine * AC.4 Andorhina - single-seat production machine with Volkswagen engine * M.1 Montalva - two-seat trainer version of AC.4 with Volkswagen engine * M.2 Trovão Azul - two-seat high-performance version with turbocharged Santana engine * Agricóptero - agricultural version 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「Super Rotor Andorinha」の詳細全文を読む スポンサード リンク
