FIELD: shipbuilding.
SUBSTANCE: vessel on a compressed air flow comprises a body with a propulsion unit which generates air pressure under the ship bottom. Bottom is made of parts arranged at different angles, at that bottom is equipped with side skegs equipped inside longitudinal pressure channels made in the form of hollow through pipes from light aluminum alloy. Housing comprises a propulsion unit in the form of a coaxial impeller connected to an internal combustion engine, wherein the coaxial impeller screws are of left and right rotation and the angles of attack of the blades are equal and of the opposite sign. On the inner cavity of the closed housing around the coaxial impeller there is additionally fixed an annular nozzle in the form of straightening device from inside. Inner walls of annular nozzle are made in form of cascading longitudinally oriented grooves around coaxial impeller and directed towards convergent nozzle. Straight grooves in annular nozzle form gap between ends of blades and inner surface of annular adapter. Along the diameter of the circular nozzle towards the narrowing of the closed body with the nozzle, the profile of the straight grooves is outlined with at least one single-threaded grooves of the coaxial impeller straightening and blown by the compressed air flow with the possibility of coinciding opposite rotation. In front part of both sides of ship hull on flat bottom side there are niches above parking waterline with automatic control of short interceptors, made in the form of plates of wing shape of aerodynamic profile and attached in niche to axis of rotation in niche with possibility of extension. Nose part is equipped at the front with a rotary interceptor with a sharp front edge. Ship's hull turns into a bottom short version with a height decreasing to zero at the waterline limit.
EFFECT: vessel on compressed air flow has simple and reliable design and is easy to maintain.
