Abstract

PURPOSE: To change over forward and backing only by revolving rudders, by each rotating a front rudder plate and a rear rudder plate independently and at arbitrary angles.
CONSTITUTION: Water current 7p formed by means of a propeller 2p is discharged to a port rear portion along a front rudder plate 4p revolved at an angle β1 centering around a rudder shaft 3p and a rear rudder plate 5p revolved at an angle θ1, thrust works to a hull 1 and the hull 1 goes ahead. In this case, the forward speed of the hull 1 can be reduced by symmetrically rotating the rudder plates. When steering angles β, θ are made large, the lowering of speed is large; when said steering angles are made small, the lowering of speed is small. Since the front rudder plate and the rear rudder plate can each be revolved independently and at arbitrary angles as mentioned above, forward and backing can be changed over only by rotating the rudders.
