The two-dimensional numerical simulations using unsteady Reynolds-averaged Navier-Stokes are performed to investigate the aerodynamic performance of SD7062 airfoil with a 0.30c single-slotted flap at cruise, takeoff, and landing conditions for various angles of attack corresponding to pre-and post-stall regimes. The time-averaged aerodynamic characteristics of the configurations are compared to the different angles of attack results and other configurations. The maximum lift coefficient value of 3.302 is obtained with 35(degrees) flap deflection for landing condition (L-2 configuration) at alpha = 14(degrees). The flow is fully attached to the flap for all deployed flap configurations except L-3 configuration at the stall angle of attack. The gap sizes from 0.010c to 0.037c with constant overlap size of -0.004c and 40(degrees) flap deflection at landing condition alpha = 0(degrees) and alpha = 12(degrees)are analysed to achieve the optimum gap size. It is found to be 0.016c.
