Abstract

FIELD: shipbuilding; water-jet propellers for river and seagoing vessels and motor boats. SUBSTANCE: jet propeller has two loops to use energy of compressed air waste gases of engine-driven compressor. First loop is provided with jet nozzle and mixer in whose center elbowshaped air nozzle is mounted. Second loop has water and waste gas supply passages; jet nozzle with head is secured on end of this loop. Air supply passage is provided with nozzle assembly; passage feeding water to centrifugal pump is provided with damper which changes flow rate of water in turning the lever and shaft. EFFECT: increased reactive thrust; enhanced efficiency of propeller.

Предполагаемое изобретение относится к судостроению, в частности к гидрореактивным движителям, и может быть использовано на судах речного и морского флота, а также на моторных лодках. Целью предполагаемого изобретения является увеличение реактивной тяги за счет использования энергии сжатого воздуха и отработанных газов мотокомпрессора, а также повышение КПД движителя. С целью использования энергии сжатого воздуха и отработанных газов мотокомпрессора, реактивный движитель выполнен двухконтурным, при этом первый контур имеет реактивное сопло и смеситель, в центре которого установлено коленообразное воздушное сопло, второй контур содержит каналы подвода воды и отработанных газов, а на конце его закреплены реактивное сопло с насадком, в канале подвода газов установлен сопловой аппарат, а в канале подвода воды к центробежному насосу установлена заслонка, которая изменяет расход воды при повороте рычага и валика.The alleged invention relates to shipbuilding, in particular to jet engines, and can be used on ships of the river and navy, as well as in motor boats. The aim of the proposed invention is to increase jet thrust due to the use of energy of compressed air and exhaust gases of the motor compressor, as well as increasing the efficiency of the propulsion device. In order to use the energy of compressed air and exhaust gases of a motor compressor, the jet propulsion device is double-circuit, with the first circuit having a jet nozzle and a mixer, in the center of which a knee-shaped air nozzle is installed, the second circuit contains water and exhaust gas supply channels, and a jet is fixed at its end nozzle with nozzle, a nozzle apparatus is installed in the gas supply channel, and a damper is installed in the water supply channel to the centrifugal pump, which changes the water flow rate when the lever is turned and roller.
