Aerodynamic performance of a penguin-inspired biomimetic aircraft wing was numerically evaluated using delayed detached Eddy simulation, where the SST K-ω model was applied as Reynolds-averaged Navier–Stokes (RANS) model. At a Reynolds number of 5 × 105, penguin-inspired biomimetic aircraft wing exhibits the flow separation characteristics after 20 deg angle of attack (AOA). Penguin-inspired biomimetic aircraft wings promise better performance compared to almost all the aerofoils if we only consider the stall effect; as for almost all the baseline aerofoils, the stall occurs at around 10–16 deg AOA. The maximum drag coefficient obtained was 0.35 for 30 deg AOA, the maximum lift to drag ratio was 7.8 at 10 deg AOA, and the aerodynamic efficiency is expected to be maximum at that point. Moreover, compared to baseline NACA0012 aerofoil, for 15, 20, and 25 deg AOA, the penguin-inspired biomimetic aircraft wing offers 30.43%, 65.94%, and 33.16% higher lift to drag ratio, respectively.
