Carried out in the TsAGI T-107 subsonic wind tunnel (test section diameter dwt = 2.7 m) has been the experimental investigation of sub-sonic flow (M=0.2-0.74; Re=3.3·10^6 -9.4.10^6) about a large-scale half-model (span 1.67 m, chord 0.73 m) of a swept untapered wing ex = 35°) equipped with a local bound-ary-layer suction.
