The invention relates to the field of shipbuilding and can be used in the construction of auxiliary propulsion.

Known auxiliary propulsion system, designed for the movement of the vessel at low speed and which includes a propeller mounted on the vessel with a rotating mechanism (see Applebees and other "Means of active management of ships". Leningrad, Izd. "Shipbuilding", 1969, str, RES). The disadvantage of this complex is a great additional hydraulic resistance created by this complex, with the main propulsion due to the absence of shield-recess.

Closest to the claimed invention to the technical essence and the achieved result is an auxiliary propulsion system swimming facilities, consisting of a propulsion system extension propulsion of the hull vessels and shield-recess (valve cover that covers the cutout in the body and restoring the continuity of the plating) (see Applebees and other "Means of active control by the courts. Leningrad, Izd. "Shipbuilding", 1969, str, RES and str, RES). A disadvantage of the known designs is the increased hydraulic resistance vessels in its motion, as the shield-recess nominated together with auxiliary propulsion complex in sweat is the fluid during operation of this complex remains in the stream.

The purpose of the present invention is to reduce the hydraulic resistance of the auxiliary propulsion complex and increase the total thrust.

This goal is achieved by the fact that in the known auxiliary propulsion complex swimming facilities, consisting of a propulsion system extension propulsion of the hull vessels and shield-recess, it is equipped with an additional system of nomination, kinematically connected with the shield-recession and located inside swimming facilities. Introduction to the design of the auxiliary propulsion complex additional system extension allows after advancement of the mover in flux return shield-recess in its place (flush with the casing and thereby to reduce the hydraulic resistance of the thruster in the thread. This is particularly important when the auxiliary propulsion system is used as the primary failure of the main propulsion. In this case, the auxiliary propulsion complex requires bringing vessels to repair base. The smaller hydraulic resistance of the auxiliary propulsion complex, the greater will be its total thrust and the greater the distance will be able to go swimming tool. To exclude the hydraulic resistance from the introduction of advanced the system of nominating the latter is located inside the swimming tools.

The main view of the proposed design outside (shown dotted) and operating conditions shown in the figure with the following symbols:

1 - body swimming facilities;

2 - propulsion;

3 - extension system propulsion of the body;

4 - shield-recess;

5 - additional extension system;

6 - cover of propulsion;

7 - zone propulsion;

8 - shaft propulsion.

The proposed auxiliary propulsion system swimming means consists of a propulsion 2, accommodated in the housing 1. Idle mover is in zone 7, which is closed by the shield-recession 4 and the lid 6 of the propulsion device, arranged flush with the shell plating. Translation auxiliary propulsion complex in a working state using system 3 extension propulsion of the body. Shield-recess 4 kinematically associated with the additional extension system 5 located inside the housing 1 swimming facilities.

Auxiliary propulsion system operates as follows. In the off position the mover 2 is in zone 7, which is closed by a cover 6 propulsion and shield-recession 4. When you receive the command to translate complex in its working position the shield recess 4 is shifted by means of the optional system extensions 5 and propulsion 2 extension system 3 displays the I in the stream. Further, the shield-recess 4 additional extension system 5 is returned to its original position, leaving open only the location of the output shaft 8 of the housing 1. After work the mover 2 is removed in zone 7 in reverse order: extended shield-recess 4 additional extension system 5, the mover 2 extension system 3 is returned to the zone 7 and the shield-recess using the system 5 is installed flush with the surface 1 swimming facilities.

When using the supporting ring complexes propulsion to reduce the amount of area 7 may optionally be entered rotator. In this case, in the off position the mover 2 is placed horizontally, not vertically, parallel to the direction of motion of swimming facilities. For other types of propulsion their promotion of the hull vessels can occur without rotation of the propeller, which will be located in the housing vertically.

The use of the proposed solution can significantly reduce the hydraulic resistance of the auxiliary propulsion complex and thus increase its total thrust.

Auxiliary propulsion system swimming facilities, consisting of a propulsion system extension propulsion of the hull swimming among the STV and shield-recess, characterized in that it is provided with an additional extension system, kinematically connected with the shield-recession and located inside swimming facilities.
