Design considerations and modeling of a small and low altitude solar powered UAV

The final goal of this study is to develop a small and low altitude solar powered UAV. In the first step, the main design parameters were considered and the dynamic modeling was carried out. For the small size and low altitude operation, the design parameters were derived from the literature study. The fundamental aerodynamics of the selected airfoil was investigated. The energy consumption for mission profile and level flight are estimated according to the various altitudes. The flight motion equation by Lagrange-Euler was derived.
