Abstract
We investigate the efficiency of a thrust vectoring system utilizing a set of vanes designed to create forward force at a minimum loss in net thrust, placed in both a stand-alone propeller configuration and a propeller-in-wing configuration. Both static and wind-on force-based experiments were conducted at the University of Dayton Low Speed Wind Tunnel (UD-LSWT) with off-the-shelf R/C propellers. A square propeller sheath was incorporated for static testing and a propeller-wing integrated setup was the focus of wind-on experiments. Sensitivity analysis was conducted to determine the effect on thrust vectoring of vane tilt angle and propeller placement with respect to the upper surface of the integrated wing. Static test results indicated notable improvement in vane performance when placing the vane system in a wing as compared to the stand-alone sheathed design. Thrust vectoring was achieved, along with subsequent changes in pitching moment, by increasing vane deflection angle. Wind tunnel test results of the integrated propeller-in-wing system indicated successful thrust vectoring below the advance ratio of 0.3, which is practical for most relevant applications. Sensitivity analysis results revealed that the case of the propeller exposed to the flow freestream outperformed that of the propeller embedded in the test wing in overall efficiency, though the embedded featured a better thrust vectoring capability. © 2021, American Institute of Aeronautics and Astronautics Inc, AIAA.
