Flow on the airfoil with deploying microtabs was performed to investigation aerodynamic performance airfoil modified with microtabs. Computer Fluid Dynamic (CFD) simulation has already been conducted to study the effects of heights deploying tab to the aerodynamic performance characteristics of airfoil sections. The aim of this study was performed to determine the effect of tab heights under variations of angle of attack againt the behaviour of stall airfoil and determine the effect of tab heights on the lift coefficient (CL) and drag coefficient (CD) on tab heights of 1.1% C, 2,2% C and 3.3% C for upper and lower surfaces airfoil. The angle of attach airfoil was from -4° to 32° with interval 2 0 . From the results of CFD simulations showed that the addition of microtabs on the airfoil Wortmann FX63-137 for the lower surface had the effect of increasing the lift force and lift coefficient, the increase occurred consistently and stall occurred at an angle of 26° for tab heights of 1.1% C and 2,2%C while the tab height of 3.3% C a stall occurred at an angle of 20°. For upper surface, microtabs caused a decrease in lift force and stalls occurred at angle of 22° for all tab heights. The drag coefficient also increased under the increasing angle of attack with highest value was at tab height of 1.1% C of 2.542 and an angle of attack of 28 0 , while on the lower surface the largest drag coefficient was at a tab height of 3.3% C of 2.73.
