The Effect of Morphing Force on Aerodynamic Performances of TM Wing

Abstract:

Twist Morphing (TM) wing is one of biomimetic MAV design that highly depends on morphing force actuation. Despite of vital morphing force influenced, the effect of morphing force variation on the aerodynamic performances of TM wing was not fully comprehended due to high complexity of fluid-structure interaction (FSI) behaviour. To elucidate the effect of morphing force influence, a series of TM wing with different morphing force intensity was used here to elucidate the effect of morphing force on C_L, C_D, and C_M distribution. Fully coupled Ansys-FSI method was employed in this study. C_L and C_M results showed that TM wing with higher morphing force configuration had induced better static stability and higher C_L distribution. However, TM wing also promoted earlier AOA_stall incidence and higher C_D penalty than the baseline wings. These situations turn out to be greater in the TM wing cases with higher morphing force configurations.
