THE PURPOSE OF THE PROPOSED RESEARCH IS TO WIND-TUNNEL TEST A METHOD FOR IMPROVING THE PERFORMANCE OF AIRPLANE HIGH-LIFT SYSTEMS. DURING TAKEOFF AND LANDING COMMERCIAL AIRCRAFT UTILIZE HIGH-LIFT SYSTEMS SUCH AS SLATS AND FLAPS TO ENSURE THAT THE WINGS PROVIDE ENOUGH LIFT FOR SAFE OPERATION AT THE RELATIVELY LOW SPEEDS OF THESE PHASES OF FLIGHT. IMPROVED HIGH-LIFT PERFORMANCE AFFECTS THE TAKEOFF FIELD LENGTH CLIMB RATE AND LANDING APPROACH SPEED.
