APPLICATION OF ARTIFICIAL CAVITIES (AC) TO DECREASE HYDRODYNAMIC RESISTANCE OF HIGH-SPEED VESSELS

There the calculating method to choose the bottom lines of high-speed vessel, which provide for the formation of AC in two given speeds, has been created. The field of effective use of AC has been extended for the speed range, which is characteristic for the high-speed displacing vessels and for ones of transient conditions. The results have been used in design of three high-speed vessels. The AC application allows to decrease the power of propulsion system by 15 - 25% or to increase the vessel speed by 5 - 10%Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
