The Hermanspann Chinook is an American mid-wing, two-seat, experimental research glider that was designed and constructed by Fred Hermanspann and Art Penz. ==Design and development== The Chinook and its improved variant, the Chinook S, have been used to study the effect of rain on airfoils and also stall dynamics.〔 The aircraft is predominantly made from aluminium with the cockpit area made from fiberglass. Its span high aspect ratio wing employs a Wortmann FX67-K-170/17 airfoil. Glidepath control is via hydraulically operated trailing edge flaps that deflect 80°. The landing gear consists of hydraulically retractable nose gear and main gear. The vertical stabilizer is highly swept.〔 The improved Chinook S features an improved wing tip design, system and structure refinements and a BRS-1200 ballistic parachute. Only one Chinook was constructed and it was registered with the US Federal Aviation Administration in the ''Experimental - Amateur-built'' category.〔〔 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「Hermanspann Chinook」の詳細全文を読む スポンサード リンク
