STRAKE SECTION IMPACT ON HYBRID-DELTA-WING AERODYNAMICS

D. Sedlacek╣, C. Breitamter╣; ╣Technical University of Munich, Germany

Highly-agility aircraft often consist of a nonslender main wing and a slender strake.Thus, two vortices form and interact with each other. In this study, the influence of the strake-length of a triple-delta and a double-delta wing on the vortex systems is analysed. For this investigation, force and moment measurements, particle image velocimetry and oil-flow visualization were conducted.
