The invention relates to shipbuilding and for the creation of máchovo-jet propulsion of surface and submarine vessels. In máchovo-jet propulsion combined two ways of moving in the water. This method according to the likeness of the fish and the method according to the likeness of squid. For this, apply the special design of the rolling body consisting of two parts, in the future, the rotor 1, with the front part 1 is made of a rigid material, and the rear part 2 of elastic and flexible material, for example, of rubber or other polymers. Connected the two parts to each other by bolts flush or otherwise. On the front, the hard part of the rotor (1) provides space for mounting cables, in the future, stretch marks, in points 4 and 5, and the drive rod 12 Fig in point 3, located at 1/3 length from the front of the hard parts of the rotor. These rods need two edges of the rotor to avoid bias during operation. On the front part of the rotor includes a shock absorber arrow-shaped form 14. The rotor is placed in the camera box section 2, and the camera can be expanded in the middle part pig on the thickness of the rotor. The camera is rigidly attached to the bottom of the ship so that between the bottom and the camera remained a gap necessary for the effective operation of the valve 8 figure 3. The levers 15 and 16 6 also rigidly attached to the bottom of the ship. Between the levers 15, 16 and the hard part of rotora currents 4, 5 are rope marks 6, 7 6.

The invention consists in that the rotor of a special design, located in the chamber of rectangular cross-section of figure 2, or in the cell and extended her middle part, to increase productivity pig, makes movements on an eccentric path. The water is forced out from the front of the camera in its rear part is as follows:

Figure 2: the Rotor is in the initial position. The beginning of the downward movement. In this position, stretch marks 6 and 7 are taut - see figure 6. The camera is schematically divided into four sectors for a complete description of the motion of the rotor along the lines A-A1 and B-B1.

Figure 3: At the beginning of the downward movement of the rotor is necessary to overcome the force of detachment from the top of the camera. What is provided plate-valve single acting 8. In the beginning of the movement it opens under the action of vacuum, and the water begins to flow through it in sector a-O-B, and then from the front of the camera and fills sector a-O-B. the Valve 9 is closed. The force F from the actuator acts on the front of the rotor so that the front end of the rotor reaches the bottom wall of the camera faster than the rear part of the rotor. At this point, the shock absorber 14 touches the wall. At the same time overlaps sector a-O-B1 front part of the rotor, and water under the action of force F starts italiasia in sector B1-A1 camera. For more stable operation of the rotor in this mode it is possible weighting of the rotor at the point 5 figure 1.

Figure 4: the end of the movement down. Hard, the front part of the rotor is pressed by the force F to the bottom wall of the camera. At this point all of the water sector a-O-B1 moved to sector B1-A1. Moreover, flexible, elastic back part of the rotor overlaps the sector B-O-A1 and prevents water from seeping from the Gaza B1-A1 in sector a-O-B, and then under the action of its own elasticity continues to push the water out of the sector B1-A1 outside the chamber in its rear part.

Figure 5: Force F changes its action on the opposite. The cycle continues to repeat in the opposite direction, that is, opens valve plate 9 and so on

Stretch marks 6 and 7 must be sufficiently long to ensure that the angle L was minimal, Fig.6, this will ensure a stable position of the rotor in the working area. Front stretch 6 holds the rotor in the working area at idle ship, and on the back stretch 7 transmitted part of the reactive force from the rotor. To convey the motion of the rotor can be from different drives: mechanical, hydraulic, and you can use the energy of the waves, equipping ships float system 13, Fig. Consider the drive from circular motion, Fig.7. Here is the obligatory condition that D is equal to N, 7, i.e. the diameter of the circular drive Rawa is the camera height H. As can be seen in Fig.7, the sector's circle especially loaded, because at this point occurs the water is forced out from the chamber. This sector is approximately equal to 60 degrees, so it is advisable to simultaneously use at least three cameras on one axis of the actuator, and thus to distribute the force F uniformly throughout the length of the circle, as shown in Fig.

Máchovo-jet propulsion pike can be placed under the bottom of the ship in a horizontal arrangement, Fig.9. Inside the ship, which is preferable for ships operating in shallow water or ice-breakers, the screws which are subject to deformation on ice figure 10. Can be operated in a vertical arrangement, for example, on submarines, 11. And, you can put the driver on a separate platform, this will allow the bottom of it to use as a separate unit, acting according to the laws of aerodynamics, using handlebars turn 10 and handlebars depth 11, Fig. The upper part of the vessel at sufficient speed will rise above the water and allow the whole structure to move without difficulty with a sufficient agitation of the water.

Máchovo-jet propulsion pike does not create turbulence as the two streams of water, separated by a rotor in the process, are formed in one laminar through the back, the elastic part of the rotor so that the propulsion is silent, what is necessary is IMO in the operation of submarines.

Máchovo-jet propulsion pike is expected to have a higher efficiency than the screw propeller, so as not throws water in hand, and all submitted to the chamber the water throws back.

Máchovo-jet propulsion pike explains theory of flight of a cockchafer, which between the abdomen and the corneal wing creates a similar reactive power.

The disadvantages of propulsion can be attributed to the complexity of the organization of movement of the ship back, but applying modern thruster means, this disadvantage can be minimized. Or, given the simplicity of the design of the mover, to have the same opposite direction, in which the main mode of movement will be closed.

Known water jet SU 1466986 A1 B63H 1/02 containing the wafer placed in the chamber of rectangular cross section, open the ends. The plate is in the first third is associated with cravings. The plate is pivotally attached to the flap. In addition, a special mechanism is reversible code, provided podpruzhineny latches mounted on the side walls of the chamber from the side of the fore and aft edges of the plate and alternately interacting with them. This thruster has a low operating characteristics because of the uncertainty of the mode of operation of the engine at initial stage and depends on the flow velocity. Passive role for the of Rilke only hinders laminarinase water movement, and in the case of reflux water in front of the camera can rasklinilsja between the top or bottom wall. The reverse is possible only with considerable complexity of the design. Springs and latches only reduce the tightness of the camera and minimize the reactive power.

As the closest analogue patented another mover EN 2122505 A 27.11.98 B63H 1/36, and EN 2152332 C1 from 20.05.99 containing attached to the hull chamber of rectangular cross-section with open ends and located in her plate, one end of which is pivotally attached to the thrust, with the possibility of rolling the camera in the plane orthogonal plates and a complete seal to the opposite plates of the camera and the other end of the plate - off camera, and the camera itself is pivotally attached to the housing or the bearing surface of the vehicle, with the possibility of transferring the camera swinging movements. Luggage mover can be divided into several chambers lesser height, each cell of which is a plate connected with cravings. This thruster has serious disadvantages: 1. When moving rigid plate across the stream at its edges formed vortex swirling flow. When the length of the plates they will SAG under the elasticity of the water, which will greatly reduce the reactive component and reduce efficiency due to reduction of weight drop is m working environment. 2. About turning the camera, when the extreme values of the rotation angles will be created vortex swirling flow, which causes the unsteadiness of the flow, disruption of the flow. Between the camera and the hull is formed stagnant zone, filled with vortices, resulting in dramatically increases drag. All these shortcomings can talk about the low efficiency of such propulsion.

Offer máchovo-jet propulsion pike does not have these disadvantages, since the rotor has a special design and front hard part is doing only useful work, pushing out from the chamber water. Rear flexible and elastic part of the rotor is also doing useful work. At the end of the movement on the water is forced out the front part of the rotor it covers the back area and prevents the ingress of water in the front area, and further under the action of its own elasticity continues to push water out of the camera. Role is also required in the rear part of the rotor so that the two split rotor streams combine into one laminar, after passing water through the working area of the rotor, and it completely eliminates turbulence, so the driver does not generate noise. Not unimportant is the role of a shock absorber, preventing the knocking at the moment of contact of the rotor chamber walls. Luggage rectangular or extended in its Central part, for which helicene performance does not create any significant resistance. The camera is equipped at the top and bottom walls of the valves is to avoid large effort at the time of separation of the rotor from the lower and upper walls. To hold the rotor in the working area there are rope marks, and on the back stretch transmitted part of the reactive force from the rotor. Tension or weakening of stretch marks, you can adjust the efficiency of the rotor. Location propulsion on ships can be both horizontal and vertical, depending on the destination. The rotor can be driven by any drive: mechanical, hydraulic, and you can also use the energy of the waves Fig using the float device 13. You can use combo drive when entering the port to operate ship's propulsion system, and in the open sea to use the energy of the waves that will lead to a great saving of fuel.
