The invention relates to the field of shipbuilding, and more particularly to the far East the surrounding devices, help reduce energy costs while creating a driving force to the vehicle.

Known rotary vane water jet (see U.S. patent N 4030442, published in 1977), containing vodoprovodny channel having the form of flat gap, a cylindrical recess in one side vodoprovodnogo channel, a rotor mounted in the cylindrical recess and photoproton channel, and at least one plate mounted in the rotor, the rotor plate mounted overlying vodoprovodny channel. This unit is adopted as a prototype.

As follows from the description of the invention the prior art, when the rotor plate is held in photoprotons channel moves the water, whereby the water is sucked through the inlet channel and is forced through the hole, creating a driving force on the vehicle. In the prototype flow in the channel is created at the moment of passing the plate in vodoprochnoi part of the channel. At the same time while passing the plate in a cylindrical recess of work to create flow in the channel are not made, although it takes power to overcome the resistance forces of interaction of the plate with water in cylindrically on the vehicle by creating a thread in photoprotons channel through the plate, interacting with water in a cylindrical recess during rotation of the rotor.

The goal is achieved in that the rotary vane jet-propulsion engine containing vodoprovodny channel having the form of flat gap, a cylindrical recess in one side vodoprovodnogo channel, a rotor mounted in the cylindrical recess and photoproton channel, and at least one plate mounted in the rotor, the rotor plate mounted overlying vodoprovodny channel, according to the proposed technical solution the rotor is installed with the minimum technological gap to the wall vodoprovodnogo channel, opposite the cylindrical recess in the rotor is made of a longitudinal slot, and a plate mounted for movement in the slots of the rotor, and the swept surface, formed by the longitudinal edges of the plate when the rotor has such a geometry that the length of its chord passing through the axis of rotation of the rotor equal to the width of the plate, and she swept surface equidistant the cylindrical wall niches and to have minimal technological gap.

The invention is illustrated by drawings, where:

Fig. 1 is a longitudinal section of the rotary vane vodopia the movement of the plate.

Rotary vane water jet contains vodoprovodny channel 1, which has the form of a flat slit (Fig. 1). In one of the walls of the channel 1 is cylindrical niche 2. In channel 1 and the recess 2 has a rotor 3 of circular cross section. The rotor 3 is installed with the minimum technological gappto the channel wall 1 opposite to the recess 2. The rotor 3 is made of a longitudinal slot 4. In slot 4 set plate 5 can move in the slots 4. The rotor 3 with the plate 5 are overlapped vodoprovodny channel 1. When the rotor 3 of the longitudinal edges of the plate 5 form a swept surface 6 (dashed line in Fig. 1). The length of the chord swept surface 6, passing through the axis of rotation of the rotor 3, the width of the plate 5. Swept surface 6 equidistant wall niches 2 and has the minimum technological gap p.

Schematic diagram of the device, providing the movement of the longitudinal edges of the plate 5 along the trajectory swept surface 6 shown in Fig. 2. Plate 5 at each end rigidly attached to the rod 7. The rod 7 has two wheel 8, which have the ability to our teams on the rim 9. Rim 9 equidistance swept surface 6.

Arrows U p the th n - the direction of movement of the plate 5 with the rod 7 in the slot 4 when the rotor 3.

Rotary vane water jet works in the following way. To create a translational motion of the vehicle drive (drawings not shown) rotates the rotor 3 in the direction of the arrow (Fig. 1). When the rotor 3, the plate 5 is rotated together with the rotor 3, and is moved in the slot 4 in the direction n. The longitudinal edges of the plate 5, moving form a swept surface 6. Moreover, when the rotor 3 cyclically one part of the plate 5 extends from the rotor 3 in the cylindrical recess 2, while its other part at the wall vodoprovodnogo channel 1, the opposite recess 2, is removed in the slot 4.

Schematic diagram of the operation of the device, providing the movement of the longitudinal edges of the plate 5 on the swept surface 6 during rotation of the rotor 3 shown in Fig. 2. This is achieved by a rigid connection plate 5 at each end with the rods 7, each of which by means of two wheels 8 rolls on the rim 9, the equidistant path swept surface 6.

Serving plate 5 of the rotor 3 in the cylindrical recess 2 in its movement interacts with the - otrejenie, creating a pressure drop. Thus, water is sucked through the inlet channel 1 and is pumped through the outlet channel 1. Formed thread in photoprotons channel 1, shown by arrows U in Fig. 1, implements the driving force on the vehicle.

You must ensure that when the rotor 3 both longitudinal edges of the plate 5 would be moved by one and the same trajectory swept surface 6. Therefore, the length of the chord swept surface 6, passing through the axis of rotation of the rotor 3 will be equal to the width of the plate 5. And for effective pressure difference, it is necessary that the trajectory swept surface 6 and the cylindrical wall niches 2 would be equidistantly and would have minimal technological gapp. Minimum technological gappbetween the longitudinal edges of the plate 5, which is moving on the trajectory swept surface 6, and a cylindrical wall niches 2 will minimize losses to create a pressure drop in the channel 1 from the flowing water in the gappbetween the longitudinal edges of the plate 5 and the wall 2 niches that will allow you to create a driving force on the vehicle with minimum energy consumption.

In the proposed rotary vane water jet due to the effective pressure difference in photoprotons channel 1 will allow you to receive driving force on the vehicle with minimum energy consumption the channel, having the form of flat gap, a cylindrical recess in one side vodoprovodnogo channel, a rotor mounted in the cylindrical recess and photoproton channel, and at least one plate mounted in the rotor, the rotor plate mounted overlying vodoprovodny channel, characterized in that the rotor is installed with the minimum technological gap to the wall vodoprovodnogo channel, opposite the cylindrical recess in the rotor is made of a longitudinal slot, and a plate mounted for movement in the slots of the rotor, and swept the surface formed by the longitudinal edges of the plate when the rotor has such a geometry that the length of its chord, passing through the axis of rotation of the rotor equal to the width of the plate, and she swept surface equidistant the cylindrical wall niches and to have minimal technological gap.
