FIELD: vessels and other watercrafts.
SUBSTANCE: method is intended for obtaining additional pressure of gas lubricant under the bottom for high-speed ship on compressed airflow. Vessel has a body with a propulsion plant creating pressure of air under the bottom and moving the ship. Bottom is made of parts arranged at different angles and equipped with longitudinal pressure channels in form of hollow pipes from light aluminum alloy. Channels are connected at ship nose by means of pipe with source of all hot flue gas of ICE exhaust pipe to form high-pressure water cavern, which is connected to output of all flue gas with pressure channels, ends of which are plugged from stern part. Mixing of dissimilar high-pressure active media coming out behind the stern is formed under the ship bottom. ICE operation is combined with operation of high-pressure injector in the form of impeller in compressor mode, which creates high-pressure gas-pressure jet coming out of impeller nozzle. Between the expandable bottom skegs to form a closed air channel with a rectangular short bottom towards the interface of the main open air channel of the housing bottom, the closed pneumatic channel above its lower short bottom is connected at a certain distance to the upper bottom rigidly, which is a continuation of ship hull bottom towards open pneumatic channel, with distribution gas chamber, including gas line, connected to ICE gas-slave pipes, supplying from distributing gas chamber, exhaust gases enter into longitudinal pressure gas pipelines in the form of small streamlined pipes-editions arranged in rows and parallel to each other along the bottom of main pneumatic channel, ends of which are plugged, and in their lower part there are exhaust slots supplying exhaust gases to lower open water bearing surface, on both sides from lateral skegs inside in longitudinal direction and above their support ends there are small streamlined forms of pipe-editions with slots, and are connected additionally to distributing gas chamber.
EFFECT: higher seaworthiness and ship speed.
