Abstract

Neutral buoyancy craft of architecture according to which all the necessary for its guidance, navigation and control forces act exclusively on part A (2.1) which locates between the craft's extreme front and the Drag's application center D as the surrounding flow's axis is parallel to the craft's longitudinal axis and its direction from its front portion towards its back. The part A (2.1) which may be an independent part connected to the rest of the craft by means that ensure the effective transfer of powers from the one part to the other allowing also the relative rotation between the two parts by 360 degrees around the craft's longitudinal axis.
