| Summary: | The study of wing with varying aspect ratio is critical in the development of the morphing wing for Unmanned
Aerial Vehicle (UAV). A morphing wing permits a change in the camber, aspect ratio, wing twist and wing
sweep while simultaneously supporting structural wing loads. UAV with this wing design will be able to carry
out multiple objectives mission. This paper investigates the effect of aspect ratio on the stability of the
longitudinal and lateral motions of UAV. The poles of the motions are calculated and root locus for the motions
are plotted to validate that the variable aspect ratio (VAR) wings sustain stability during symmetric changes in
wing span. Preliminary study on the stability of a generic UAV shows that it remains stable for values of aspect
ratio from 3 to 10. |
