We continue our study on the aerodynamic investigation of two propellers mounted partially overlapping and in tandem configurations. In the previous study, the rear propeller was placed above the plane of the front propeller (negative stagger). The current study placed the rear propeller beneath the plane of the front propeller (positive stagger). Different vertical and horizontal spacings, incidence angles with respect to the freestream, and advance ratios were tested experimentally at the University of Dayton Low Speed Wind Tunnel. Thrust and torque were measured separately on each propeller. A significant increment in the power required of the tandem propeller system was observed when compared to the results in the previous study under negative staggered conditions. A higher loss in system efficiency at small forward flight speeds is also observed due to propeller wake interaction. The advance ratio at which this performance loss occurs is affected by the propeller spacing and incidence angle. © 2024 by Jielong Cai, Sidaard Gunasekaran, Michael OL.
