title = "Experimental investigations of an elasto-flexible morphing wing concept",
abstract = "This paper discusses the design and testing of an elasto-flexible morphing wing configuration allowing massive variation of the wing planform. The wing structure consists mainly of an articulated leading edge spar over which an elastic skin is spanned, forming the actual aerodynamic surface. The configuration of the leading edge spar, actively controlled, sets the overall planform of the wing whereas the elastic membrane just passively deforms under aerodynamic loading. A wind tunnel half model of the wing was tested at three different wind speeds. Results from force measurements show the dynamic pressure dependency of the aerodynamic characteristics due to the high flexible wing construction. Also, the comparison of the drag polars of three different configurations of the wing show that planform morphing effectively provides significant variation in lift and drag characteristics, thus allowing to improve aerodynamic efficiency over a variety of missions.",
