Experimental and Computational Investigation of Propeller-Wing Aerodynamics during Transitional Flight Mode

Abstract

Transition flight in VTOL is challenging as the aircraft experiences wing stall, large propeller induced moments (1), uneven wing load distributions (2), unsteady effects (3,4), and (in the case of small UASs) low-Re dynamics (5-19). While research has shed light on the unsteady aerodynamics of wings undergoing translation-rotation (20-27) and the effect angle-of-attack has on the performance of propellers (28), there is a lack of fundamental understanding of the effect of unsteady kinematics on propeller flow behavior and performance, the interactive effects between the propeller and wing when combined, and the impacts of the complex motion and flow dynamics on the propeller-wing system performance.
