AERODYNAMIC VESSEL Russian patent published in 2007 - IPC B60V1/14 B60V3/06 

FIELD: shipbuilding; dynamically supported vessels.

SUBSTANCE: proposed vessel has hull with navigator and passenger compartments, main engine mounted inside fore part of hull, propulsors for vertical lifting which are kinematically linked with main engine, cruising engine mounted inside aft part of hull and kinematically linked with two horizontal motion propulsors and control mechanisms. Vertical lift propulsors are similar in construction; each disk of these propulsors has lower smooth surface. Upper surface has alternating concentric half-round troughs and concentric half-round ridges. Each concentric half-round ridge is divided into several parts and each part has bevels at the front and at the rear with through vertical passages in between them; longitudinal axis of each of them lies at angle relative to lower surface of disk and in parallel relative to rear bevel of ridge standing in front of it. Height of concentric half-round ridges and depth of concentric half-round troughs are equal to radii of similar circles whose centers lie in one line which is equidistant from lower surface of disk. Two horizontal motion propulsors are similar in construction. Each propulsor is made in form of horizontal hollow cylindrical housing with reduction gear mounted in center; reduction gear has front and rear horizontal shafts on which front and rear groups of variable-pitch propellers is secured. Air propellers are mounted at some distance from one another. Diffuser mounted in rear part of hull is turned away from air propellers by its wide part.

EFFECT: simplified construction of cruising engines; increased lifting force of vertical lift engines.
