FIELD: marine propellers. ^ SUBSTANCE: proposed marine propeller belongs to propellers with reciprocating working member-piston and is used on surface ships and habitable submarine ships. Operation of propeller is based on principle of motion of sea mollusk squid using pulse reaction jet of water. Used as drive for working member-piston is engine working both on hydraulic fluid and on compressed air delivered from high-pressure bottles. Engine is installed on watercraft hull in fore, midship and aft sections for controllable turn in horizontal or vertical plane, thus ensuring motion of watercraft in any direction. ^ EFFECT: possibility of continuous creation of thrust; simplified construction; absence of propeller shaft and rudder; enhanced ecology of water area. ^ 1 dwg |
