N2 - Interactions between UAV propellers and other objects are investigated with respect to their mutual influences using a Vortex Lattice Model for all considered bodies, which are coupled with a Free Wake Model. To increase overall calculation performance the mirror method commonly used for the prediction of helicopter ground effects is modified and applied to the obstacles. The wake vortex sheets are furthermore able to separate and subsequently flow around an obstacle. Wake vortices are possibly reunited after obstacle passage. This procedure greatly enhances the computational accuracy and enables the consideration of more complex obstacles. The model is embedded in the "Synthesis and Analysis Rotor Environment" (SARF) data framework which provides a flexible and dynamic simulation environment that reduces manual work on the creation of the geometric mesh.
