Abstract
The influence of distributed suction on the hydrodynamic drag and some boundary layer characteristics on a body of revolution were investigated experimentally in a test basin. The results obtained permitted making a conclusion about the possibility of an essential reduction in the hydrodynamic drag (1.5–2-fold) and the level of velocity fluctuation (10–30 dB) in the boundary layer by using suction of small quantities of water through a porous skin (6.10−4 discharge coefficient).
