FIELD: transport.
SUBSTANCE: invention relates to ship building and may be used as propulsor for various overwater and underwater vessels. To create water-jet propeller reversible gear pump. Outside water is delivered to each pump section via suction channels in vessel hull which channels are changed to be water-jet in reverse mode. Discharge channels of sections are combined into at least one water-jet nozzle and changed into suction channel for outside water in reverse mode, and the water-jet nozzle is equipped with adjustable head piece to change reaction force of water-jet stream. To accelerate executed manoeuvre the vessel fore end has additional gear pump which has discharge water-jet trumpets positioned perpendicular to vessel axis.
EFFECT: high travel speed and manoeuvrability, lower acoustic power, higher vessel survivability.
