Aerodynamic models for high-amplitude, low reynolds flapping airfoils

Abstract

In this thesis a new aerodynamic model of insect-like flapping flight for micro air vehicles has been developed. The New Predicted Aerodynamic Model (NPAM) was based on the model described by Weis-Fogh model in Energetics of Hovering Flight in Hummingbirds and Drosophila. In order to achieved the NPAM some variations were introduced regarding the geometry of the problem under study and also some improvements was done to the theory developed by Weis-Fogh. To have the required inputs for the model, a fitting from a DNS database for lift and drag coefficient, and aerodynamic efficiency was performed. Finally, the DNS database was also used to determine the accuracy and validity of the New Predicted Aerodynamic Model.
