Abstract

The geometric twist characteristic on twist morphing MAV wing has significant influence on its aerodynamic performances. Higher geometric twist magnitude induces higher lifts and drags generation. However, in order to determine the geometric twist performance, a detail analysis has to be carried out to extract the local angle of attack (AOA) value on each wing cross section. Thus, current works introduces a new method in extracting the local AOA value on a twist morphing MAV wing. The method manipulates the automated coordinate generation produced by Ansys software and combined the generated coordinates with manual determination of local AOA magnitude. Based on the analysis executed on a twist morphing wing sample, 30 local AOA values were obtained from 30 wing cross sections. By using the local AOA value at the root chord and wing tip, the geometric twist magnitude or twist intensity for a twist morphing wing is determined. Based on a selected twist morphing MAV wing sample, the local AOA extraction method able to calculate the wing geometric twist at ϵ = 12.5°.
