Description
本出願は、2006年11月21日に出願の独逸国特許出願第10 2006 055 090.0号、および2006年12月4日に出願の米国仮特許出願第60/872,704号の出願日の利益を主張し、それらの出願の開示は本明細書において参照することにより援用される。
遷移領域とウィングレットとの間の円滑な接続を提供するために、この領域において、曲率における局所的な低減を有することは有利である。本発明の利益は維持されるので、遷移領域の幅方向寸法の50%から90%に亘る、翼の接続部付近において、低いレベルまたはゼロレベルから最大にまで、局所的な上反角の曲率が増加する遷移領域を提供することができる。
