A design method and analysis tool of an UAV propeller based on Blade Element Momentum Theory (BEMT) for low-Reynolds number flow is presented. BEMT is completed with 3D equilibrium-implementation, a post-stall model and swirl velocity considerations to improve the accuracy of the results. An open-source code, JBlade, based on BEMT is used to obtain performance curves in off-design cases for a given propeller. Finally, the results are analyzed for a UAV Hirrus propeller. This methodology can be used successfully in the preliminary design phase of an UAV propeller, whose data can then be used as input in an optimization method. [ABSTRACT FROM AUTHOR]
