<p>The invention relates to shipbuilding engineering, in particular to reverse steering devices for a water-jet propulser which can be used for controlling small vessels operating, for example, on shallow areas of rivers. The inventive reverse steering device for a water-jet propulser comprises a stream directing duct which is arranged upstream of a nosepiece and is provided with input and output branch pipes, with side reversible channels and with a steering mechanism located at the output of the branch pipe. The invention is characterised in that the steering mechanism is embodied in the form of several parallel rotatable blades, the total surface area of which is equal to the surface area of the output duct, each blade being provided with a rotary actuator which is dependent or independent or in part dependent on the other blades.</p> |
