초록

Ducted fan UAVs that are able to vertical take-off offer a higher static thrust/power ratio for a given diameter than open propellers. In this study, we have analyzed the fluid calculated using the Ansys Fluent in the actuator which is based on a three-dimensional flow field measurements. The duct cross-section has implemented a NURBS curve can be determined only by adjustment point curve. NURBS curve has implemented the curve of the duct cross section using the open library OpenNURBS. The highest thrust is generated when the culmination of outside wall for duct.When the trailing edge of airfoil shape for duct cross-section in 1mm cutoff, the highest thrust occurs in the duct.
