This study exploresthe interaction between a propellerand various framearm geometries,which are typically used in multi-rotor applications. The influence of the arm on the propulsiveperformance of the propelleris investigated by using commercial computational fluid dynamics (CFD) solver ANSYS Fluent 17in hovering flight. CFD results are validated for hover and vertical climb conditions with thrust and torque measurements conducted on a 16x4 carbon fiber propeller. Four different arm geometries (i.e., an Eppler arm, a cylindrical tube, a square tube, and a slotted square tube) are studiedto investigate their effect on the propulsive performance of the propeller and the complete propeller-arm configuration. Regardless of the geometry, the arm enhances the thrust generation of the propellerfor all propeller-arm distances considered in this study. However, the total thrust of the propeller-arm configuration is smaller than the single propeller case due to drag exerting on the arm. In this respect, the Eppler armconfigurationhas the best performance in terms of the total forcegenerationdue to relatively low drag of the Eppler profile. Thesquare arm configuration yields the highest thrust generation and propulsive efficiency for the propeller despite having the lowest total force generation.
