The ARV Super2 is a British two-seat, strut-braced, shoulder wing, tricycle landing gear light aircraft designed by Bruce Giddings.〔"Pilot" magazine, June 1985 page 6〕 Available either factory-built or as a kit, it was intended to be both a cost-effective trainer〔Green 1987, pp 26-27〕 and an affordable aircraft for private owners.〔''Flight International'' 6 April 1985, pp. 13–14.〕 Later called the "Opus", it gained US Federal Aviation Administration Light-sport aircraft approval in February 2008.〔Johnson, Dan (2102), (Opus Aircraft LLC ), retrieved 17 March 2012〕〔Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 67. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X〕 About 35〔Moss, Roger (January 2010), (ARV2 ), retrieved 17 March 2012〕 aircraft were produced in the 1980s before the Isle of Wight-based company went into liquidation.〔(OPUS ARV Super 2 (United States), Aircraft - Fixed-wing - Civil ). ''Jane's.com''. Jane's Information Group. 19 February 2010. Retrieved 9 September 2010.〕 Subsequently there have been a number of attempts to restart production, all unsuccessful, of which the most recent was by Opus Aircraft. In November 2013, Opus Aircraft announced that its assets had been auctioned off successfully, adding: "We hope to see our plans continued and to see the all-aluminum plane flying by 2015".〔(【引用サイトリンク】title=Opus Aircraft )〕 ==Design and development== Richard Noble, the world 1983 land speed record holder and UK entrepreneur, identified a gap in the market for a low-cost lightweight two-seat trainer, after expensive product-liability lawsuits in the USA had driven the major American general aviation manufacturers temporarily to abandon production of such aircraft. Noble established a factory at Sandown on the Isle of Wight to build the ARV Super2 aircraft, with the first prototype flying on 11 March 1985.〔 The factory used some novel manufacturing techniques, including British ALCAN's "Supral"〔 (a superplastic aluminium alloy), adhesives (to reduce rivet count and save weight), and a bespoke new British engine, the Hewland AE75. These innovations gave the ARV an empty weight 40% lower than the Cessna 152,〔Blech 1986, p.47.〕 making the Super2 both cheaper to buy and to operate. The manufacturer claimed it could reduce pilot training costs by 25%〔 The ARV Super2 is a side-by-side configuration two-seater with a shoulder wing for improved visibility.〔"Pilot" magazine February 1986 pages 32-33〕 The wing is swept forward 5° to maintain correct center of gravity balance.〔 The wing area is a small , giving a wing loading of 11.9 lb/ft² (58.1 kg/m²).〔 The forward sweep may also promote a spanwise airflow inwards towards the root, thereby reducing the likelihood of a wingtip stall. The ARV's tapered fibreglass wingtips help to reduce drag from wingtip vortices. The ARV is constructed mainly of aluminium alloy, with fibreglass wingtips, cowlings and canopy frame.〔〔"Pilot" magazine, June 1985 pages 5-6〕 The cockpit is a stiff monocoque of "Supral" alloy for lightness and improved crash protection. Aft of the cockpit bulkhead, the ARV is conventionally built, with frames, longerons and a stressed skin forming a semi-monocoque. Skin sections are both glued and riveted. The aircraft has twin control sticks, and all controls are pushrod, except the rudder, which is cable-linked. Both flaps and trim are mechanically operated. The rudder pedals control a steerable nosewheel, but the hand-operated disc brakes are not differential and do not contribute to steering.〔 The AE75 engine, a 〔〔 inverted three-cylinder water-cooled two-stroke unit with dual ignition and a 2.7:1 reduction gearbox,〔"Air Pictorial" magazine April 1986〕 was specially developed for the ARV by Hewland from their existing two-cylinder microlight engine. The AE75 engine has a TBO of only 800 hours, and, in the absence of continuing factory support, many ARVs have had their AE75s replaced with engines such as the Rotax 912, the Rotax 914, or the Jabiru 2200.〔Civil Aviation Authority (United Kingdom), (GINFO Search Results ), retrieved 15 December 14〕 Three ARVs were originally manufactured with the MidWest twin-rotor wankel engine.〔"Pilot" magazine April 1994 page 22〕 The Super2 gained airworthiness certification in July 1986,〔 and soon after entered production. In November 1985, Noble had reached an agreement to supply ARV parts to Canada's Instar Aviation, where the aircraft was intended to be assembled for the North American market. Transport Canada had agreed to certify the aircraft based on it "meeting UK criteria", but in the end these Canadian production plans came to nothing.〔"Canadian Aviation" magazine December 1986〕 Originally, ARVs were available either as kit-built aircraft (subject to PFA Permit), or factory built (and subject to the CAA Certificate of Airworthiness). In the spring of 1990 Aviation Scotland Limited was to restart production and in 1993 that company intended to set up another facility in Sweden to build ARVs.〔Purdy, Don: ''AeroCrafter - Homebuilt Aircraft Sourcebook, Fifth Edition'', page 174. BAI Communications, 15 July 1998. ISBN 0-9636409-4-1〕 In the late 1990s the aircraft was sold in kit form in the USA as the Highlander by Highlander Aircraft Corporation of Golden Valley, Minnesota.〔 In 2004, the CAA reclassified all ARVs as PFA (now LAA) Permit aircraft. The ARV Super2 was originally intended to be aerobatic, but the Isle of Wight factory closed before CAA clearance was obtained, so aerobatics remain prohibited. Also, the factory had planned to develop a four-seater version, wing-tip tanks and floats.〔"Pilot" magazine February 1996 page 34〕 Opus Aircraft upgraded some specifications for the aircraft, increasing the Vne to and increasing the gross weight to . The company intended to equip the aircraft with the Rotax 912UL or 912A of . 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「ARV Super2」の詳細全文を読む スポンサード リンク
