The Boeing 7J7 was a short- to medium-range airliner proposed by American aircraft manufacturer Boeing in the 1980s. It would have carried 150 passengers and was touted as the successor to the successful Boeing 727.〔 It was initially planned to enter service in 1992.〔 This was intended as a highly fuel-efficient aircraft employing new technologies, but it was cancelled when the price of oil dropped during the 1980s. ==Design and development== The 7J7 was planned to include advanced technology and electronics, such as: * fly-by-wire flight control system by Bendix * glass cockpit by Honeywell utilizing LCDs * advanced integrated avionics suite〔 * widespread use of high-strength composites such as carbon-fiber〔 * two General Electric GE36 UDF rear-mounted advanced technology contra-rotating unducted fan (propfan) engines.〔 The sum of all these features promised better fuel consumption by more than 60% compared to any existing large passenger aircraft technology at the time. "Efficiency" was the key theme. The 7J7 was to have a twin-aisle〔 (2+2+2) seating configuration, giving an unprecedented wide and spacious cabin for its class, with no passenger more than one seat from an aisle. 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「Boeing 7J7」の詳細全文を読む スポンサード リンク
