In aircraft design, a chine may be one of several features: *On a fuselage of any aircraft, a chine is the longitudinal line of sharp change in the cross-section profile *In seaplane design, a hard chine 〔Angled chine, different from soft (rounded) chine〕 is the longitudinal line of sharp change in hull cross-section, meeting of bottom plane with lateral panel, as in the hull of a powered planing boat. *The longitudinal sideways extensions of a chined-shaped fuselage are usually called chines ; this kind of fuselage is also called "chined fuselage", "chined forebody", "chine shaped forebody".〔NASA-aiaa-98-2725 ''Impact of fuselage cross-section on the stability of a generic fighter'' uses "chined-shaped fuselage cross section, chined forebody, fuselage with ... included chine angle" expressions. NASA CR 189641 and AIAA 2008-6228 use "Chine forebody and Chine fuselage"〕 The usual appellation is "chine" or sometimes strake.〔 This article discusses this type of chine. ==Configuration== A chine shaped fuselage may be described as a fuselage featuring sideways extensions, or long extensions of the wing roots along the fuselage. Chines first appeared on the Lockheed A-12 precursor of the SR-71 Blackbird, where they formed forward extensions of the wing roots along the fuselage sides into which they blended.〔 The Lockheed Martin F-22 Raptor has chines that lead to the leading-edge extensions that are blended into the engine air intakes. A small horizontal surface forming a fillet between the main wing root and the fuselage, more usually called a Leading Edge Root eXtension (LERX) or Leading Edge eXtension (LEX), is also sometimes called a chine. 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「Chine (aeronautics)」の詳細全文を読む スポンサード リンク
