Abstract
The efficiency of a lifting surface depends, among various things, on the downstream wake. In addition, the overall efficiency of an aircraft is strongly influenced by the wake of the lifting surfaces itself. This effect is evident if we consider the topic of propeller-based vehicles, which is nowadays widely gaining momentum in the community. Due to this increasing interest in the electric distributed propulsion for urban air mobility and UASs, it is relevant to find a fast yet reliable tool, to evaluate the performance of such propellers. Nevertheless, analyzing the flow field downstream of the propeller is a complex and time-demanding task, especially in the early stages of the design process, where an incorrect evaluation of these effects may have repercussions on many aspects of the project.
This thesis proposes a relatively fast yet accurate algorithm to evaluate the flow field downstream of the propeller, based on the Vortex Particle Method, which became popular in the early 90s
