| Abstract: | Birds are able to control their perching and landings manoeuvres very well, during these manoeuvres the covert feathers lift up. In literature it has been shown this lifting can have an influence on the flight characteristics of the wing. Research on this topic aims to provide a valuable insight into how these aeroelastic devices function and what kind of influence they have on the aerodynamics of the wing. Most research done is on the static case, this work instead focuses on flapping manoeuvres. This work tries to find out how the lifting of covert feathers influence the airflow over the wing. This is done by using Particle Tracking Velocimetry and analyzing the movement of the Leading Edge Vortex for a wing with imitated covert feather flaps. By looking at how different design parameters for these imitated flaps influence the flight characteristics in the static case, a flap is chosen. Through these methods a flap was found that for the static case had an improvement of 35 % at an angle of attack of 18°and higher. Using Particle Tracking Velocimetry it was found that for this flap the detachment of the Leading Edge Vortex is delayed by approximately 100 ms . |
