AbstractInsect flight is often investigated in tethered animals, while free-flight studies show behavior in a more natural context. However, approaches that analyze wing and body motion in unrestricted flight are relatively seldom due to technical challenges. The aim of this PhD thesis was to capture and analyze time-resolved kinematic data of both wings and body in freely flying fruit flies (Drosophila melanogaster). Independent from specific maneuvers, correlations between wing motion, body posture and body motion were calculated, showing that correlations between wing and body kinematics are mostly small. The best correlation was found between wing tip velocity squared (proportional to flight force production) and the vertical acceleration of the body´s center of mass. The results also show how body motion changes wing kinematics relevant for force production (wing tip velocity, angle of attack). Further experiments using transgenic fruit flies demonstrated the significance of reduced flight muscle mechanical power on voluntary take-off behavior, resulting in changes in wing kinematics and reduction of body velocities and muscle mass-specific lifting power.dc.description.abstract
