Title:
WATER JET TYPE PROPULSION SYSTEM FOR MARINE VESSEL
Document Type and Number:
Japanese Patent JP2009126509
Kind Code:
A
Abstract:

To provide a water jet type propulsion system to directly pressurize and jet sea water, etc. by high pressure by combustion of fuel by using the sea water and water existing in the circumference of a marine vessel as a main power transmitting medium, to extensively improve thermal efficiency of the high speed navigation marine vessel, to increase application of it to the low speed navigation marine vessel and to establish it as a power source of high thermal efficiency.

The incompressible and high density sea water or the water is used as the power transmission medium with pressure energy as a standard, used for supply and compression of air for combustion, both of the sea water and the air are divided in an engine working under high pressure, combustion of the air and jetting of the sea water are thermally separated and made to work, and energy transmission is carried out by pressure between both of them. Concretely, pressurization of the sea water and compression of the air are carried out by a centrifugal pump after the sea water and the air are mixed, they are separated after they are taken in the water jet engine working under high pressure, the high pressure air is delivered to a combustion chamber provided on an upper part in the middle of a high pressure accumulator water pipe to move the sea water to a jetting port, high pressure of high pressure combustion gas generated by burning the air with fuel is directly transmitted to the sea water and the high pressure sea water is jetted.
