Description
Technical field
The present invention relates to marine propeller technical fields, and in particular to a kind of straight wing rudder of novel ship.
Background technique
Straight wing rudder is also known as voith schneider propeller, is a kind of driving tool of ship, is suitable for tugboat, ferry boat, minesweeper.
Straight wing rudder is on a special flat disk, and that installs several vertical flat disk planes is rectangle blade substantially, these paddles
Leaf can not only be rotated with flat disk, moreover it is possible to pass through operating mechanism own rotation.In the specific position of disk, blade own rotation is
Along angular speed normal direction, and then rotating in other positions is along angular speed direction, so that only in the paddle of blade disk specific position
Leaf just generates biggish thrust, and the blade of other positions does not generate thrust substantially.The motive force that can produce any direction, makes
Ship pusher can be pushed away with side, pusher and any cant, and can non-stopping switching direction of propulsion.Mobility is adapted to want
High naval vessel is sought, such as tugboat, ferry boat and minesweeper.Its propulsive efficiency is lower than drving sprial paddle propeller.Main application at present
It in port tug, needs to carry out the complicated occasion frequently changed direction, has screw propeller combination tail vane can not
The effect of analogy.
But the structure of straight wing rudder causes its thrust direction not pass through its rotation center, but along rotating cylinder tangential direction, cause
The straight wing rudder thrust in two sides generates unbalanced moments, turns to hull.When hull adjusts course, which navigates to ship
Row influences less, but when hull keeps navigating by water forward along course, will lead to hull off-course, make hull course unstable.
Thus need to solve the problems, such as that straight wing rudder thrust generates unbalanced moments.
Chinese patent CN205931204U, publication date on 2 8th, 2017, a kind of Double-motor direct wing all direction propeller peculiar to vessel,
