HELICE DE SEPARATION D'EAU, A MONTAGE AVANT

A FRONT-MOUNTED WATER-SEPARATION PROPELLER

Abrégé français

L'invention concerne, sur la base de la loi de la séparation dynamique de l'eau, un nouveau type d'hélice de séparation d'eau à renfort, à montage avant, mis au point pour augmenter la vitesse de rotation d'une cuve, par réduction de la résistance côté eau et par augmentation de la force d'avancement. Ladite hélice comprend deux parties. La partie extérieure comporte un tube affluent(1), un trop-plein de débordement (2) plat et mince, gauche, et un trop-plein de débordement (2) plat et mince, droit, ainsi que des raccordements vissés (6). La partie intérieure comprend un élément de renfort (4) et son axe (5). Les deux parties peuvent être remplacées indépendamment l'une de l'autre.

Abrégé anglais

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 (1), a left thin, flat gushing gutter (2), a right thin, flat gushing
gutter (3), and screwed connections (6), of which interior includes a booster
(4) and its axle (5). Both parts can be changed independently.

CLAIMS
1. A type of front-mounted booster, water-separation propeller, of which the
feature lies in
its composition of an influence tube, a left thin and flat gushing gutter, a
right thin and
flat gushing gutter, a booster and its axle, screwed connections. An influence
tube, a left
thin and flat gushing gutter, a right thin and flat gushing gutter and screwed
connections
compose the external part of this invention; and a booster and its axle
compose the
interior part of it. This inventive installation will be attached on the
vessel with screwed
connections.

mentioned in
claim1, the invention consists of the feature that the two thin, flat gushing
gutters, of
which the directions are open toward side back of the vessel.
3. According to the front-mounted booster, water-separation propeller above-
mentioned in
claim 1 or 2, the invention consists of the feature that the direction of the
influence tube
is open toward right front of the vessel.
4. According to the front-mounted booster, water-separation propeller above-
mentioned in
claim 1, 2, and 3, the invention consists of the feature that the sum of the
areas of the
outmost cut-off planes of two gushing gutters is equal to the area of the cut-
off plane of
influence tube.
5. According to the front-mounted booster, water-separation propeller above-
mentioned in
claim 1, 2, 3, and 4, the invention consists of the feature that external part
of this
invention which is composed of an influence tube, a left thin and flat gushing
gutter, a
right thin and flat gushing gutter and screwed connections, is an
independently
changeable part.
6. According to the front-mounted booster, water-separation propeller above-
mentioned in
claim 1, 2, 3, 4 and 5, the invention consists of the feature that the
interior part which is
composed of a booster and its axle is an independently changeable part.

A FRONT MOUNTED WATER-SEPARATION PROPELLER
TECHNICAL FIELD
This invention refers to a new type of water-separation propeller that will be
installed in front
of the vessel.
BACKGROUND OF INVENTION
Nowadays, there is no dynamic installation in the field of ship's propeller,
by which the
frontal resistance may greatly reduce and the advance force 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 resistance from water. Its frontal
resistance from water
amounts to more than 80% of the total resistance. Therefore, it is less
effective to raise the
vessel's speed by the means of either changing the external structure of the
vessel or singly
enhancing the advance force.
is CONTENTS OF INVENTION
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 and its axle, and screwed
connections. The 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-lilce gushing gutters to the side back
of the vessel.
This gushing high-speed water can largely push the vessel forward. Meanwhile,
with the raise
of speed of the vessel, the frontal resistance from water increases, the
gushing water with
high speed from both sided-gutter s will forms into a water-separation force
in front of the
vessel, as a result 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
change the
current configuration while attaching on the vessel. Compared to the current
technology in
this area, it fills the blank with front-mounted water-separation propeller.
It may also play an
energy-conservation, environment-protection role.

BRIEF EXPLANATION OF ATTACHED DIAGRAMS
Diagram 1 is a cross-sectional view of the structure of this invention, in
which,
1= influence tube, 2= left thin, flat gushing gutter, 3= right thin, flat
gushing gutter, 4=
booster, 5= axle of booster, 6= screwed connection.
From attached diagram, you may find the propeller of this invention consists
of influence
tube 1, left thin, flat gushing gutter 2, right thin, flat gushing gutter 3,
and screwed
connection 6, being as the external part of this invention, and booster 4,
axle of booster 5,
being as the interior part. Screwed connections are the parts of attaching
this invention on the
front of vessel.
In this invention, this propeller will start to push the vessel when the
flowing speed in the
influence tube 1 is higher than the speed of vessel, and the efficiency of
water-separation and
advance will increase with the ratio of the flowing speed in the influence
tube 1.
