Files in this Data Supplement:
- Supplemental Figure S1
-
Fig. S1. Shapes of three plates: (A) rectangular, (B) triangular and (C) delta-shaped for a duck's feet.
- Supplemental Figure S2
-
Fig. S2. Trapezoidal (blue solid line) and sinusoidal (red dashed line) angular velocity programs.
- Supplemental Figure S3
-
Fig. S3. Shape effect on thrust generation for (A) trapezoidal and (B) sinusoidal angular velocity program cases (Re=19,720). Note that the y-axis value in these graphs is not the thrust coefficient, but the thrust measured by a load cell.
- Supplemental Figure S4
-
Fig. S4. Comparison of non-dimensional impulse for the Re=19,720 and Re=140 cases in the (A) trapezoidal and (B) sinusoidal velocity programs.
