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.
