Aeroelastics Flight Dynamics Coupling Effects of the Semi-Aeroelastic Hinge Device

A recent consideration in aircraft design is the use of folding wing-tips with the aim of enabling higher aspect ratio aircraft with less induced drag, but also meeting airport gate limitations. This study investigates the impact of floating folding wing-tips on the aircraft flight dynamics. It is found that a floating wing-tips aircraft has similar handling qualities with respect to an aircraft with no wing extension.
