Abstract

We continue our study of a powered wing’s response to streamwise gusts and investigate its performance. A full span aspect ratio 2.67 wing model with different propeller installation locations was subjected to streamwise gusts of varying reduced frequencies in the University of Dayton Low Speed Wind Tunnel (UD-LSWT). A range of angles of attack between -10 to 20 degrees under both steady and unsteady conditions were tested. An increment in the lift coefficient and pitching moment coefficient response was found at higher reduced frequency for the powered and unpowered wings. At low angles of attack, the differences in powered and unpowered wing’s responses are nearly identical across all reduced frequencies. The peak CL and CM occur at different phase angles at different reduced frequencies. However, at higher angles of attack, the deviation between powered and unpowered CL increases with increase in reduced frequency. This deviation is caused by the added energy to flow around the wing by the propeller, which prevents flow separation. However, the deviations also depend on the location of the propeller along the wingspan and its advance ratio. © 2024 by Lucas Duncan, Jielong Cai, Sidaard Gunasekaran.
