Planetary Exploration Using Biomimetics An Entomopter for Flight on Mars A set of 3D cases was run with the same conditions as of the 2D case, and for the same angles of attack. A triangular mesh with 119,105 cells was used. The meshing was much denser near the airfoil surface than in the previous mesh. Figure 3-59 shows the airfoil with the new grid. Figure 3-59: Airfoil with New, Finer Triangular Mesh To determine the effect of thickness on the lift and drag coefficients, another set of cases was run for an infinitesimally thin airfoil. Figure 3-60 shows the airfoil used for these cases. Eight cases were run with the same conditions as used previously and given in Table 3-5.

Chapter 3.0 Vehicle Design 3.3 Wing Aerodynamics The lift and drag coefficients obtained for the thick and thin airfoils were compared. Figure 3-61 shows a comparison of the C L values and Figure 3-62 shows a comparison of the c d values.
