The Reggiane Re.2007 was thought to be an Italian fighter aircraft designed in 1943 by Roberto Longhi. Longhi himself spread the word on his design and construction of a jet aircraft prototype during the war. ==Design== Roberto Longhi, one of the most prominent Reggiane aircraft designers, in a letter to the Italian aviation magazine JP4, dated May 1976, stated that Regia Aeronautica Major Antonio Ferri asked him to study an engine option for the Reggiane Re.2005. The requirement was to install a supplemental Fiat A.20 engine behind the cockpit, driving a compressor, in order to improve the Daimler-Benz DB 605 main engine output, giving the airplane a speed of above . It was also planned to use a tail exhaust to achieve more thrust. The proposal was filed as ''Project R'' by Regia Aeronautica ''Stato Maggiore'' (HQ), but remained only a paper project, as, according to Longhi, the aircraft would have had problems with its center of gravity.〔 One alternate possibility was to obtain turbojet engines from Germany, but despite requests from Antonio Alessio and Count Giovanni Battista Caproni, the Germans delivered only a wooden mock-up for dimensional tests to Reggiane.〔 After the war, Longhi tried to conduct experiments with two Junkers Jumo 004 engines that were left in Udine airport after the German defeat. These extremely valuable jet engines were delivered to Italy in 1945 as spare parts for a small Luftwaffe high speed reconnaissance flight, equipped with three Arado Ar 234 ''Blitz'', when the nearly impossible to intercept German twin-jet planes participated to the Italian Campaign. Unfortunately for Reggiane's designers, the engines were purchased by Angelo Ambrosini, another Italian aircraft manufacturer.〔 Some Re.2007 drawings were made only after the war by airplane designer Pellizzola, but were not followed-up.〔 Those Re.2007 drawings were based on a speculative reconstruction derived from a Reggiane engineer's description.〔 The drawings were notable for the futuristic (for 1943) swept wing, which only became common on fighter planes in the 1950s, although the Germans had used them on both the Me262 jet and Me163 rocket fighters. Rumours about a partially built airframe with technical sketches, both sent to the United Kingdom and the United States for studies, were published in some Italian books and magazines, but are now considered highly improbable. 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「Reggiane Re.2007」の詳細全文を読む スポンサード リンク
