PROPULSION UNIT FOR HIGH-SPEED TRAVELING ON MARINE RAILWAY

摘要

The present invention relates to a propulsion unit for high-speed driving on an underwater track. Disclosed is the propulsion unit for high-speed driving on the underwater track comprising: a main body in which components are built in, a hollow unit is formed in a shaft direction inside the center, a front end part is sealed, and a rear end part is opened; a fuel chamber formed at the inner front end of the main body and in which the propulsion unit is bui a nozzle assembly for covering the rear end of the main body and increasing the fluid speed of discharged combustion gas; and a pipe exposed to the outside by penetrating through the center of the hollow unit and the nozzle assembly.
