An experimental study on aerodynamic effect of lateral blowing for flat delta wings with three different planforms and a rectangular wing has been conducted. Lateral blowing is realized by injecting a pair of jets parallel to the trailing edge of the wing. Experiments have been conducted in the wind tunnel of Kyushu University under a test condition of free-stream velocity V∞=20m/s, Reynolds number Re=2.6×105 and 5.3×105, and jet momentum coefficient Cμ=0.07. Results show that increase of lift due to lateral blowing in all wing types is obtained over a wide range of angle of attack. The lift-increase ratio of flat delta wing with small sweepback angle and the rectangular wing is larger than that of the other wings in high angle of attack region. We could investigate aerodynamic effects of lateral blowing on the flat delta wings with various planforms and rectangular wing.
