Abstract
We continue our study on the aerodynamic investigation of two propellers mounted partially overlapping and in tandem configurations. In the previous study, the force-based experiment was conducted in both positive and negative staggered configurations. The current study implements smoke flow visualization and Particle Image Velocimetry (PIV) techniques to further investigate the propeller flowfield in tandem configuration. All experiments were conducted at the University of Dayton Low-Speed Wind Tunnel (UDLSWT) in the open-jet configuration. A decrement in back propeller inflow angle was observed in the flow visualization experiment and confirmed by the PIV measurement. By applying the propeller performance prediction model developed in the previous study, the changes in the back propeller thrust generation in tandem configuration were predicted. © 2025, American Institute of Aeronautics and Astronautics Inc, AIAA.
