The LH-10 Ellipse is a two-seat light aircraft kitplane designed by LH Aviation of France. It is a low-wing single-engine pusher configuration with a tandem seating arrangement, and is constructed of composite materials.〔(【引用サイトリンク】LH Aviation )〕〔Bayerl, Robby; Martin Berkemeier; et al: ''World Directory of Leisure Aviation 2011-12'', page 63. WDLA UK, Lancaster UK, 2011. ISSN 1368-485X〕 The plane is marketed in a surveillance configuration as the Grand Duc (eagle-owl). == Development == The LH-10 Ellipse was conceived by Frenchman Sébastien Lefebvre, starting as an engineering grande école (university) project to conceive "a small plane with different design and performance than available for private pilots". This led to the founding of the company, LH Aviation, in May 2004. As a surveillance plane, Sébastien Lefebvre conceives of the plane as an alternative to drone UAVs, the latter being costly to operate especially near airport. The Ellipse aims to "deliver 80% of the range of drone missions for 20% of the cost".〔 The potential of the plane for surveillance and military missions led the investment fund ''Magellan Industries'' to become a shareholder in LH Aviation. The Ellipse was thus further developed in collaboration with Thales as a modular platform for civilian and military missions with different equipment systems including day and night vision, rocket launching, and on-board communication systems.〔 The LH-10 Ellipse is a low-wing, tandem two-seat light kit aircraft, powered by a 100 hp Rotax petrol engine in a pusher-prop configuration. Its low weight and unusual configuration is designed to deliver a very high cruising speed with exceptional fuel economy.〔 This high speed and a relatively high 50-knot stall speed will exclude it from the UK Microlight or US LSA categories, so a full single-engine private pilot license will be the minimum license requirement to fly it in these countries, which are not the immediate target of the manufacturer, anyway. At the 2008 Farnborough Airshow LH-Aviation said that for the future they would be looking into LSA/ELA compliant production, possibly for the US. In February 2010, the aircraft began a series of tests required to achieve the French CNSK standard (an acromym for ''Certificat de Navigabilité Spécial Kit'', the French kitplane certification). The company reported that "all construction documents have been validated in December 2009 by the French and English authorities." 〔Air et Cosmos n°2206 - February 19, 2010 - pp.14〕 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「LH Aviation LH-10 Ellipse」の詳細全文を読む スポンサード リンク
