AERODYNAMIC CRAFT Russian patent published in 2006 - IPC B60V1/14 B60V3/06 

FIELD: shipbuilding.

SUBSTANCE: proposed aerodynamic craft has hull, propulsors for horizontal motion actuated by cruise engine, propulsors for vertical lift located in through vertical passages of hull and control system for steering the craft in space. Novelty of invention consists in form of each propulsor of vertical lift: propulsor has cylindrical body closed with grates at the top and at the bottom; vertical shaft mounted inside body is used for securing upper and lower pressure wheels; lower wheel is lesser in diameter. Each pressure wheel is made in form of bush secured on vertical shaft and connected with rim by means of spokes. Secured on upper surface of rim are air intakes whose inlet openings are open in way of rotation of pressure wheel; rim body has vertical passages according to number of air intakes; each vertical passage is made in form of Laval nozzle. Radial blades of straightening apparatus are located below each pressure wheel.

EFFECT: improved aerodynamic properties.
