DEVICE FOR REDUCING HYDRODYNAMIC RESISTANCE OF BOTTOM OF VESSEL ON COMPRESSED PNEUMATIC AIR FLOW Russian patent published in 2018 - IPC B60V3/06 B63B1/38 B60V1/04 

FIELD: transportation.

SUBSTANCE: invention relates to the field of creating vehicles using a dynamic air cushion, and applies particularly to small vessels on a pneumatic flow. Proposed device reduce the hydrodynamic resistance of the bottom of the vessel on a compressed pneumatic air flow, containing the bottom, made of parts at different angles, the steering wheel, the longitudinal air intake channel of the injection device in the form of an impeller, air from the nozzle of which is supplied under the bottom of the vessel, pneumatic channels, characterized in that the bottom is located between the side skegs at some distance above the lower support ends of the skegs, while the longitudinal air intake channel in the form of a nozzle has its continuation in the direction of the expanding bottom of the vessel with skegs, between which is formed a closed pneumatic channel with a rectangular bottom, also located at some distance above the lower supporting ends of the skegs, ending without reaching the stern, which comes from a source of compressed air, the bottom of a closed pneumatic channel located between the skegs, which is made to follow the shape of the bottom of the case, is made along the entire length with transverse exhaust channels at an angle of 30°–60° towards the stern, however, they are made with additional inclined planes, divided in the middle part by a horizontal axis of rotation attached to the walls of the exhaust channels, in addition, the upper part of the inclined plane inside the closed pneumatic channel has a visor directed towards the air flow, with the possibility of closing the transverse exhaust channels in the bottom of the closed pneumatic channel, and the lower part is made with a visor directed towards the stern, with the possibility of adhering to the lower part of the bottom, in addition, the rotative axes of the inclined planes are interconnected by levers for moving the inclined planes in the vertical plane simultaneously using the hydraulic control drive.

EFFECT: technical result is to improve the operating characteristics of the vessel.
