Apex fences are applied to improve low-speed aerodynamic characteristics of 60 deg. delta wing model. The longitudinal forces and moment acting on the thin delta wing with apex fences (Apex fences are used hinged to the delta wing upper surfaces along the leading edges at angles of 45,90 and 135 degrees.) are measured by using universal multi-component sensor and static pressure distribution on the upper surface is also measured by using pressure transducer with pressure scanner. Combination of total-pressure distribution maps and longitudinal force and moment measurements provide information on the three-dimensional nature of the vortex structure induced by apex fences.
