Abstract
Experimental results of subsonic flow over a straight wing model are described. On the surface near the leading edge a local separation bubble exists, and besides, downstream the separation of turbulent boundary layer in the trailing part of a wing is observed. A three-dimensional vertical structure of flow is noted using visualization. By means of hot-wire measurements the quantitative data on distribution of mean velocity of flow above a wing, as well as on amplitude and frequency spectra of pulsations are obtained. P. 493-498
