Abstract
In a wind tunnel experiment a morphing wing with span extension and camber morphing was investigated. The considered aircraft is an unmanned aerial vehicle (UAV) with a span of 4 m. During the investigations a half wing model was analysed with pressure and structural measurement. The half wing model has three different morphing mechanisms. The focus is on the morphing leading edge concept, which will be shortly described with the main objectives. First of all the morphing leading edge will be described. Afterwards the results of the wind tunnel measurement for pressure distribution, balance and deformation measurement will be presented and discussed.
