Title:
A JET PROPULSOR
Document Type and Number:
WIPO Patent Application WO/2006/133606
Kind Code:
A1
Abstract:
A jet propulsor is provided with helical blades or guiding grooves on the inner wall to increase the friction of fluid, so that the loose fluid is pressurized to converge and twist, which forms the interior pressure and generates great thrust. In addition, there is less air in the fluid, and the friction of bubble is small, so the noise can be greatly decreased. Since the invention don’t adopt the conventional propeller as the thruster, the cavitation can be avoided, the fluid drag problem is also prevented. Therefore the thrust can be greatly increased.
