Wind/Gust/Wake Sensing and Suppression with Aircraft Formation Flight
Birds fly in V or echelon formations for energy saving as well as enemy defense. The follower bird usually flies in the wakes generated by the leader bird. However, it is unclear how exactly birds interact with the wake vortices during close formation flight. Small UAVs offer ideal platforms for further understanding of the interaction between the aircraft and the flow field such as wake vortices generated by the leader aircraft. Such researches could potentially lead to significant fuel saving of commercial flights and help decreasing the waiting time at airport terminals.
Optical flow has been used by insects and birds for navigation functions such as obstacle avoidance, speed regulation, landing, etc. It also has big potentials to support small UAVs for short-range navigation in GPS-degraded or GPS-denied environments.
