Abstract

A power device, the prototype for which can be found in any reaction device, for example a hydraulic propeller. The latter can be modified by means of an arrangement, in the flow direction, of a reasonable number of partitions with openings, in the form of, inter alia, meshes or fabrics, since the thrust is determined by the level of pressure on the parts of the structure and the partitions make it possible to substitute a single pressure drop at the exit by a reasonably large number of smaller drops, and because the flow rate is determined by only one reasonably small drop, it becomes significantly less. Furthermore, circulatory movement of a working fluid can be brought about in at least one chamber, where the flow is directed toward the centre by blades on one wall in order that jets having a raised pressure level collide; on the other wall, airfoil-shaped blades have a tangential orientation in order to swirl the flow as it moves from the centre at a reduced level of pressure. This design makes it possible to avoid outward expulsion of the working fluid by virtue of connecting a low pressure chamber to a high pressure chamber via a pump.

Description

POWER DEVICE.

A variety of power devices are known that create power due to the reaction of the jet. For example, engines or propellers jet or jet. Among jet engines, detonation engines can be distinguished. For example, "pulsating detonation engine" according to patent RU 2432483 C1.

Until now, a prerequisite for obtaining force from a moving liquid or gas was considered to be dropping some of them at the highest possible speed. And the reactive force was calculated precisely through the ejection velocity, for example, through the Tsiolkovsky equation. Rare and not noticeable were references to the fact that the reactive force is obtained due to the resulting force from the pressure of the liquid or gas on the transverse direction of the received force of the area of the parts of the device structure, for example, a jet engine. Therefore, patent RU 2116223 C1 is not actually known, where it is indicated that the force appears from the pressure of the medium. In particular, the aircraft flies when exposed to a pressure drop on the wing, which “disappears” at small distances from the wing. As well as the weight of a moving water skier is not felt after a few centimeters. The increased efficiency of detonation engines is caused by a reduced flow rate at a fairly high pressure level.

This invention allows to reduce the flow rate of the medium, for example through a water jet, so that it becomes possible to dispense with the release of liquid or gas. Those. channel from the exit direct again to the entrance.

The power device contains parts of the structure with different levels of medium pressure over an area transverse to the received force. For example, in the form of cavities alternating in the direction of the received force, separated by various kinds of constrictions, for example, membranes with holes or grids of at least three through which the medium flows. In another way, this can be done in the form of at least one cavity, the walls of which have at least one scapular guiding apparatus. To create a higher level, on the wall surface, of pressure, the blades have a direction to a center for organizing a collision of jets, and for a low level, to another surface, they have a tangential direction to create a rotational movement. Such surfaces may define one or more cavities. One of the options for the device can be performed in the form of a cavity with scapular devices and tangential approach, and exit to alternating cavities. A cavity with a lower pressure is connected by a channel to a cavity of a higher pressure.

The drawing illustrates the invention.

Here in figure 1 shows the simplest version of the sequential arrangement of the cavities.

Figure 2 - option with the tangential motion of the medium.

In Fig.Z is a view along section BB on a scapular apparatus creating an increased level of pressure.

Figure 4 is a view along section B-B of the blade apparatus creating a reduced pressure level.

The device contains cavities with liquid or gas, on the surface of which forces from the pressure of the medium act. They can be arranged sequentially along the direction line A of the received force. Those. first there is a cavity 1 (Fig. 1) with an increased level of pressure of the medium, then a cavity 2, then 3, then 4, then 5, etc. To create an increased level of pressure in the cavity 1, a pressure device in the form of a pump or screw 6 can be installed. The cavity 1 is limited by the surface of the wall 7, on the one hand, and the surface of the wall 8, on the other. The latter has one or more holes 9, which reduce the total surface of the wall 8, in comparison with the wall 7. The next cavity 2,3, 4,5, etc. also limited by walls 10,11,12, etc. with holes, for example 13, which can be so small that the walls are made of nets or special fabric. Alternatively, one or more cavities can be made as shown in Figs. 2,3 and 4. Here, 14 and 15 are the walls of the cavity 16, with different pressure levels. On the wall 14 there is a scapula 17, and on the wall 15 one or several scapular devices 18 located at different radii. The scapula 17 has one form, mainly directed, in the direction of flow, towards the center (Fig. 3), and scapulae 18 already have a different look, for example, in the form of wing profiles with a tangential direction (Fig. 4). At the outlet of the cavity 16, the same system of cavities 19 can be installed as in FIG. 1, and the supply can be tangentially through the channel 20. The implementation of the power device according to this invention eliminates the emission of matter outside by connecting the output and input parts through the channel 21 ( figure 1).

During operation, a liquid or gas, for example, with a screw 6, is supplied with increased pressure into the cavity 1 (Fig. 1) or into the cavity 16 (Fig. 2). Then it flows through the holes in walls 9, 10, 1 1, 12, etc., or in system 19. The described construction creates a resultant, unsupported force in the direction A.

In well-known, for example, water-jet or jet propulsors, the acceleration of the liquid occurs, as a rule, from one chamber through the narrowing outward, and the entire pressure drop immediately goes to the acceleration of the entire mass of the liquid, for example, in accordance with the Bernoulli equation. In the present invention (Fig. 1), the pressure drop is divided by the number of walls 8, 10, 11, etc., and the speed of passage of the liquid is determined by the expendable cross-section of the holes in these walls or partitions. And this speed becomes smaller by the square root of the number of walls, because it is determined by the pressure drop on only one “locking” partition. Since the total speed, due to the increased number of cavities and walls, is small, this almost does not affect the resulting force, as if there was only one cavity 1 (Fig. 1). In the cavity 16 (figure 2), a circulating movement occurs, while the apparatus 17 directs the liquid jets to the center for their collision, which increases the level of pressure of the medium on the wall 14, thereby obtaining a force in the direction A. The devices 18 impart a rotational, tangential velocity to the flow high efficiency and a reduced level of pressure on the wall 15, opposite the wall 14. The installation of the system 19 (figure 2) increases the overall level of pressure in the cavity 16.

When performing the device according to the variant shown in figure 1, the greater the number of walls 8,10,11, etc. or the more holes in each wall, the less you can make the distance between them, because the lower the pressure drop across each wall and the smaller the change in speed. As the walls, you can use nets or fabrics, and fill the cavities with appropriate fillers, with low resistance to movement. It is possible to use consecutive contractions such as the Loval nozzle, which is less effective.

According to this invention, it is quite simple to modify conventional, for example, jet propulsors (fluid or air flow from section 22 to section 23 in FIG. 1). or you can loop through channel 21.
