【 摘 要 】

Capitalizing on the basic fundamental principles, the Fluid Dynamics and Flight Mechanics of a semi-spherical Coand MAV configurations are revisited and analyzed as a baseline. A mathematical model for a spherical Coand MAV in hover and translatory motion is developed and analyzed from first physical principles. To gain further insight into the prevailing flow field around a Coand MAV, as well as to verify the theoretical prediction presented in the work, a computational fluid dynamic CFD simulations for a Coand MAV generic model are elaborated. The mathematical model and derived performance measures are shown to be capable in describing the physical phenomena of the flow field of the semi-spherical Coand MAV. The relationships between the relevant parameters of the mathematical model of the Coand MAV to the forces acting on it are elaborated subsequently.
