Title:
JET PROPULSION SYSTEM OF SHIP
Document Type and Number:
WIPO Patent Application WO/2012/093499
Kind Code:
A1
Abstract:
Propulsion systems in conventional ships utilizing a screw system have already reached the limits of improvement of the screw and also the limits of hydrodynamic improvement of the bow portion, and aircraft have achieved a much higher propulsion force and increases in size with the invention of the jet engine over the propeller. However, the project of using jet engines in ships was problematic because fuel cannot burn under water. However, noting that the mass of water is a thousand and several hundred times greater than that of air, if a certain degree of volume increase can be achieved, a power conversion is possible that is commensurate with the expansion energy of the explosive air of the fuel. An additional important advantage of this design is the decreased water resistance at the bow.
