The Rutan Model 61 Long-EZ is a homebuilt aircraft with a canard layout designed by Burt Rutan's Rutan Aircraft Factory. It is derived from the VariEze, which was first offered to homebuilders in 1976. The prototype, N79RA〔(FAA REGISTRY N-Number Inquiry Results )〕 of the Long-EZ first flew on June 12, 1979. ==Design== The Long-EZ was a clean-sheet scaled up redesign of the VariEze predecessor. Changes from the VariEze included a larger main wing with modified Eppler 1230 airfoil and less sweep—the canard uses the same GU25-5(11)8 airfoil as the VariEze—larger strakes containing more fuel and baggage storage, slightly wider cabin, and the ability to use a Lycoming 108 hp engine with no nose ballast. Plans were offered from 1980 to 1985. As of late 2005, approximately 700 Long EZ's are FAA registered in the USA. In January 1985, it was announced that plans for a new canard were being offered, to eliminate "rain trim change" that had been experienced by Long-EZ pilots.〔"Long-EZ Canard Update", The Canard Pusher Vol. 43, January 1985.〕 This trim change is usually a nose down trim change experienced when flying into rain requiring a small aft force on the stick to maintain altitude, which is easily trimmed out, using the bungee trim system. The new canard was designed with the Roncz R1145MS airfoil, which produces considerably more lift than the original GU25-5(11)8 airfoil. This enabled the new canard to be designed with less span, reducing wetted area and thus drag. The new canard has a negligible rain trim and the rain only adds 2 knots to the stall speed. The aircraft is designed for fuel-efficient long-range flight, with a range of just over .〔 〕 It can fly for over ten hours and up to on 52 gallons (200 liters) of fuel.〔Rutan Long-EZ Owners Manual, Second Edition - October 1983〕 Equipped with a rear-seat fuel tank, a Long-EZ has flown for 4,800 miles (7,700 kilometers). The pilot sits in a semi-reclined seat and controls the Long-EZ by means of a side-stick controller situated on the right-hand console. In addition to having an airbrake on the underside, the twin tail's wing-tip rudders can be deflected outwards to act as auxiliary airbrakes.〔 In 1996 Burt Rutan Awarded TERF Inc. the job of publishing the plans for the Long EZ and other of his aircraft under The Rutan Aircraft Factory CD ROM Encyclopedia for the purpose of further assisting new builders and maintenance for existing builders.〔"Rutan Aircraft Factory Encyclopedia: Volumes 1, 2 & 3", Terf Inc., 1996.〕 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「Rutan Long-EZ」の詳細全文を読む スポンサード リンク
