Abstract
Based on the law of dynamic water-separation, in this invention, a new type of front-mounted booster water-separation propeller has been designed to raise a vessel's speed by reducing resistance from water and increasing the advance force. It's composed of two parts, of which the external includes an influent tube, a left thin, flat gushing gutter, a right thin, flat gushing gutter, and screwed connections, of which interior includes a booster and its axle.
Both parts can be changed independently.
Both parts can be changed independently.
Description
A hRON'I'-MOUN'T'ED WATER-SEPARA'T10N PROPELLER
'TECHNICAL FIELD
'1'lrls IIlVelrtl()lr refel'S to a new type of wafer-separation propeller that will be installed in front of the vessel.
13AC'.1~(.ItOtINU OF INVENTION
Nowadays, there is no dynamic installation in the field of ship's propeller, by which the frontal drag may greatly reduce and the advance forge may increase, as to raise the vessel's speed. It's known that the density of water is over 800 times higher that of air. When a vessel is navigating, it encounters drags from water. lts frontal drag from water amounts to more than 80°,% of the total drag. 'I'lrereCore, it is less effective to raise the vessel's speed by the means of either changing the external structure of tloe vessel or shyly enhancing the advance force.
(.."ON'I'ENTS OF INVI~NTION
This new type of propeller is composed of an influent tube, a left thin, flat gushing gutter, a right thin, flat gushing gutter, a booster acrd its axle, and screwed connections.
Ttre booster sucks the water through the influent tube right from the front of the vessel, and then conveys the water with high speed by both wing-like gushing gutters to the side back of the vessel. This gushing high-spec;d water can largely push the vessel forward. Meanwhile, with the raise of speed of the vessel, the frontal drag from water increases, the gushing water with high speed from both sided-gutters will forms into a water-separation force in front of the vessel, as a re:;ult of reduce of resistance. Moreover, this gushing water may become turbulence to reduce.
the useless efficiency caused by the induced-flow.
'this inventive design is structurally simple, costly low, ensuring no need to eharr~;e the current coni7guration while attaching on tire vessel. Compared to the current technology i:u this area, it fills the blank with front-mounted water-separation propeller. It may also play an enerty-conservation, environment-protection role.
BRIEF EXPLANATION OF ATTACHED DIAGRAMS
Diagram I i1 a cross-sectional view of the sinrcture of this invention, in which, i influence tube, 2== left thin, flat gushing gutter, 3=-= right thin, flat gushing gutter, 4= booster, 5= axle of booster, fi-- screwed cotrlrection From att<rched diagram, you may find the propeiier of this invention consists of influence tube l, left thin, flat gushing gutter 2, right thin, flat gushing gutter 3, and screwed connection G, being as the external part of this invention, and booster ~, axle of booster 5, being as the interior part.
Screwed connections are the parts of attaching this invention on the frUrlt of vessel.
In this invention, this propeller will start to push the vessel when tire flowing speed in the influence tube 1 is higher than the speed of vessel, acrd the efficiency of water-separation and advance will IIlCreirSe wltll the ratio of the Ilowing speed in the influence tube 1.
