Evaluation of Effect of Taper Ratio on Aerodynamic Characteristics of MAVs

In this investigation، a numerical method based on potential flow for aerodynamic analysis of morphing MAVs has been developed. At first، results of this method are validated with experimental data and then، effect of taper ratio in range 0. 3 to 3. 0 on aerodynamic characteristic have been studied. Results show generally increasing taper ratio، whether is the range of zero to one or bigger one، cause increasing lift coefficient and improving performance of the MAVs. The only disadvantage of taper ratio of bigger one is appearing large pitching moments. Of course، in MAVs is negligible due to the small size. In this study، also a mechanism for creation of different taper ratios has been discussed.
