EN The main purpose of this article was to study flaps application influence on airfoil, which flies in the wing in ground effect with lift, and drag coefficients changes. Wing in ground effect occurs in the direct proximity of ground, it makes lift coefficient higher than in free stream flight, also decreases drag coefficient. WIG effect craft can be an alternative for traditional aircraft, but also for marine transportation. The article presents wing in ground effect creation mechanism description with height coefficient explanation, also presents experimental analysis of lift coefficient with reference to height coefficient. Airfoil with flaps simulation and for free stream flight. Application of flaps makes the wing in ground effect more efficient by lift coefficient rise, what provides also to drag coefficient rise. Flaps provide to absolute pressure rise under the airfoil. It allows to fly slower without lift force change or to make aircraft start shorter without risk of stall. The article shows also conditions and results of Ansys Fluent software simulation for NACA M8 airfoil for angles of attack equal to: 0°, 6°, 10° for three different cases: free stream flight, wing in ground flight with the clear wing, wing in ground flight with flaps, and conditions of analysis convergence.
