Abstract

Potential of energy extraction from onflow inhomogeneity in spanwise direction was investigated theoretically. Trajectory optimization was performed for a 5 meter span UAV with morphing capability as well as without it. Results show that energy extraction from inhomogeneity in spanwise direction is of little practical relevance compared to gust soaring. Morphing can be effectively used for drag reduction and stabilization while flying in a turbulent windfield.
