(54) MOTOR VEHICLE

FIELD OF THE INVENTION The invention relates to shipbuilding, in particular to ship propulsion devices.

Known propulsion and steering device of the vessel, containing two jet propulsion, installed in the aft end of the vessel, each of which has a jet tube, the output of which is equipped with a balance wheel and two reverse deflectors, forming side channels 1.

A disadvantage of the known device is that the maneuverability of the vessel in reverse gear is significantly impaired compared to forward travel, since when maneuvering in reverse gear, the thrust assault and steering force decrease due to the part of the water flow from the propeller in the slot formed between the feather a rudder and jumper separating both pipes, as well as throwing the stern of the vessel when reversing from forward to the rear and back.

The purpose of the invention is to increase traction in the reverse and improve; ship maneuverability.

The goal is achieved by the fact that the propulsive-steering device of the vessel is made with a drainage channel connected between them and the drainage channel communicated with them, formed by two lateral vertical walls parallel to the center plane of the vessel, and

10 rear inclined wall, conjugated to the stern and bottom of the vessel.

Fig, 1 shows the stern of the vessel along the diametral plane, the section; in fig. 2 - propulsion and steering device,

Propulsion and steering device of the vessel contains two jet tubes 1 with side vertical plates 2,

installed pipe end 1, g-screws, 3 reversing deflectors 4,5,6 and 7, two balavsiry rolls 8 common drainage canap 9 and two lateral channels 10. The common drainage channel 9 is formed by vertical walls 12 and 13 and an inclined wall 14. The stern tip of the vessel has a valance 15 and lower platforms 16. The propulsion propulsion device at the rear of the vessel operates as follows: Е130М. Through the pipes 1, the screws 3 direct the water flows to the reversing deflectors 4,5,6 and 7, the steering wheels 8 divide each stream into two parts, which are bounded above by valving 15 and below by the bottom platforms 16. Turning backwards and passing through channels 9, 10 and 1, the divided streams provide the vessel with reverse gear. When maneuvering in reverse, the rudders 8 are shifted to the On board position. Water flows from pipes 1, reflecting from the rudders 8 and deflectors 4 and c. .:. : a, t; then: with c; lal The gap between the rudder 8 and the end of the pipe 1 is blocked by the plate 2. Thus, both water flows, created by propellers, are fully involved in creating the steering force. The use of this invention in pusher tugs makes it possible to create a sea-going vessel with increased thrust and improved maneuverability in the rear ode, which makes it possible to operate it while driving heavy duty crews on rivers with limited dimensions of the channel. Mula of the invention The propulsive-steering device of the vessel, containing two jet propulsion units, installed in the stern end of the ships, each of which has a propulsion tube, at the exit of which install a balance steering wheel and two reverse deflectors, forming lateral channels, characterized in traction effort on the back way and improvement of the ship maneuverability, it is made with a drainage channel between the water cannons and the drainage channel formed with them, formed by two lateral helixes. second wall, the mating of kormoksh woodcarving and bottom of the vessel.
