Description

The invention relates to devices for creating traction for aircraft and other vehicles.

The known “Method for creating traction” according to the patent of the Russian Federation No. 2104188, publication 02/10/98, priority 03.01.96, IPC B 60 V 1/14, which consists in the fact that the chamber having at least one outlet to the environment is filled with fluid under pressure and use a jet curtain of fluid.

Known “Vortex propulsion” by A. with. No. 1713209, publication 01/20/96, priority 06/27/89, IPC B 63 H 11/00, in which the propulsor contains a central body that forms mountainous vortex chambers, from which the flow is directed into the diffuser.

The known “Method of creating a lifting force and a device for its implementation” according to the patent of the Russian Federation No. 2089420, publication 10.09.97, priority 01/31/96, IPC B 60 V 1/06, in which a central stream of compressed air is fed into the area under the domed body and formed an air cushion under this dome, the jet being blown radially towards the lower surface of the bottom of the dome-shaped body in the form of a fan-shaped or flat jet.

Closest to the invention is German patent No. 3742771 “Aircraft”, publication 29.06.89, IPC B 64 C 29/02, in which air is supplied to the toroidal chamber and then ejected through an annular nozzle, thereby creating a lifting force.

Known devices do not exhaust the range of possible devices for creating traction.

The technical problem to which the invention is directed is the creation of a simple in design and efficient device that creates a lifting rod.

A device for creating traction includes a housing with a camera and a supercharger. The cavity of the chamber is made in the form of a flattened ellipsoid of revolution and is in communication with the external environment through an opening in the housing located in the lower part of the chamber parallel to the plane passing through the major axis of the ellipsoid of revolution of the chamber cavity. The supercharger is installed in the housing opening on the axis of symmetry passing through the small axis of the ellipsoid of rotation of the chamber cavity, with the possibility of pumping the fluid inside the chamber cavity.

A supercharger sucks in a fluid external medium and pumps it into the housing along the axis of the chamber. A stable toroidal vortex forms inside the chamber. A uniformly distributed overpressure is created in the cavity. Due to the excess pressure, the vortex is squeezed from the walls of the casing and part of the fluid is thrown out into the gap formed in the opening of the casing between the surface of the vortex and the casing. Supercharger energy is used to maintain the vortex and pressure inside the housing. Uncompensated pressure on the upper part of the chamber cavity creates a thrust applied to the device with the vector up.

If the side walls of the chamber cavity in the section passing through the small axis of the ellipsoid of revolution of the chamber cavity have a shape close to the shape of a part of the circle, then the toroidal vortex is more stable.

Said supercharger can be made in the form of a fan and attached to the housing by at least two rigid connections. In this case, the fan runs with a horizontal impeller.

When using the external medium in the form of air, the width of the chamber cavity in the widest part is from 8.6 D to 9 D, where D is the outer diameter of the passage section of the supercharger, and the height of the chamber cavity is at least 4 D.

The technical solution is illustrated by drawings.

Figure 1 shows a vertical section of a lifting device; figure 2 is a bottom view of the lifting device; figure 3 is a diagram of the movement of the fluid in the lifting device.

A device for creating traction includes a housing 1 with a chamber 2 and a supercharger 3 (Fig. 1). The cavity 4 of the chamber 2 is made in the form of a flattened ellipsoid of revolution and is in communication with the external environment through an opening 5 in the housing 1. The hole 5 is located in the lower part of the chamber 2 parallel to the plane of symmetry 6 (Fig. 3) passing through the large axis 7 of the ellipsoid of revolution of the chamber 4 cavity 2. The supercharger 3 is installed in the hole 5 of the housing 1 on the axis of symmetry 8, passing through the small axis of the ellipsoid of rotation of the cavity 4 of the chamber 2. The side walls 9 of the cavity 4 of the chamber 2 have a shape close to the shape of a circle.

The supercharger 3 is made in the form of a fan with a horizontally mounted impeller 11 and is fastened to the housing 1 by rigid connections 10. A guide nozzle 14 is installed on the supercharger 3.

When using the external medium in the form of air, the width of the cavity 4 of the chamber 2 in the widest part is from 8.6 D to 9 D, where D is the outer diameter of the passage section of the blower 3, and the height of the chamber cavity is at least 4 D.

The hole 5 in the housing 1 (Fig. 3) is formed by the intersection of the cavity 4 of the chamber 2 with a conical surface 12 having an apex in the center of symmetry 13 of the cavity 4, the axis of symmetry coinciding with the vertical axis of symmetry 8 of the cavity 4, and forming, located at an angle α 20 -40 ° from the plane of symmetry 6 passing through the major axis 7 of the cavity ellipsoid of rotation.

A device for creating traction works as follows.

During the operation of the supercharger 3, a fluid medium, for example air, is pumped through the guide nozzle 14 along the vertical axis of the chamber 2 into the cavity 4, where a stable toroidal vortex is formed. The jet from the supercharger is decelerated on the wall of the cavity 4 opposite from the supercharger, and the kinetic energy of the jet passes into the potential. Inside the cavity 4 in the area bounded by its surface, the surface of the vortex and the supercharger 3, a uniformly distributed excess pressure is created, which creates a lifting force. A toroidal vortex makes it difficult for air to escape from cavity 4, however, a part of the fluid is ejected out through the gap formed between the surface of the vortex and the edge of the housing 1.

This device can be used both in air, in this case a fan can be used as a supercharger, and in another medium, for example in water, in this case a screw can be a supercharger.

The device can be used for various vehicles, including disk ones. Devices for creating traction on the vehicle can be installed several. In addition, this device can be used as a traction device for various types of ships, for example, an air cushion.
