The invention relates to vehicles and construction concerns amphibious hovercraft and can be used for the AVM for any purpose: military AVM, transport, sports, etc.

When different ships in their classes and characteristics common disadvantage of known devices is their limited speed in movement, where the main propulsion (propellers, tail horizontal stabilizer with Elevator and Trier installed on your wing devices, etc.) is ineffective.

The operation of such ships, mostly based propulsion by increasing the number of revolutions of the output shaft of the engine. Hovercraft picks up speed and goes out of range of the "screen effect" and makes the movement, for example, the water regime.

Known hovercraft, comprising a housing, injection plant, with a steering device, enclosure air-cushion with bow and stern elements and side lower balloons, as well as the element separating region of the airbag on the left and right camera, made in the form of a flexible duct with a longitudinal crest in the lower part, divided internally by a longitudinal aperture on the left and right sections, which are connected with the pressure setting in a ring, �while in the walls Flex, adjacent to the chambers of the airbag, the opening communicating each section of Flex duct with a corresponding chamber airbag (patent RU 2167775, CL B60V 3/06, 1/16, 2001).

This technical solution adopted for the analogue of the present invention.

The disadvantage of this hovercraft is the limited power of the air shaft propeller when driving in a climate that requires more powerful engines fitted for movement on the water (in the air) engines, and this limited the speed characteristics of the engine with the use of advanced propulsion, where the main propulsion (propellers or nozzles) is inefficient, using only the density of the atmosphere.

Thus, when moving, for example, amphibians afloat is impossible to increase the power (thrust) without any additional hardware, without changing the discharge fitting in the field of repulsion, only using the air density is known in advance.

Known vehicle on an air cushion, comprising a housing with a rigid flat bottom with a flexible enclosure, the air bag comprising side lower balloons, front and rear flexible elements and rigid boards, engine, propulsion and injection plant, the mechanism of their Pref�and control system and inflatable Board, mounted on a rigid hull sides around the perimeter of the vessel. The outer edge of the side skegs amphibious vessel mounted on an inflatable Board, and the inner edge on the bottom of the hull. Amphibious vessel is configured with a Central skeg, the discharge setting is complete with a steering device for regulating the injection of air into the chamber. Amphibious ship made with control dampers placed on the discharge installation. The lower balloons made with protectors. Corps amphibious vessel made detachable. The bottom of the hull amphibious vessel are flat, and his nose portion is inclined at an angle of attack relative to the horizon. Propulsion amphibious vessel made in the form of a pusher propeller in a ring, which is set horizontal and vertical aerodynamic rudders. For air propeller in a ring rigidly mounted on a rectangular frame, on which the vertical and horizontal rudders. Horizontal and vertical rudders are made of a compound having, for example, the stationary and the deflecting part. Injection setup is capable of receiving its torque power of the engine through a belt transmission (patent RU 2126773, CL B60V 3/08, 1999).

In the known invention, the mover may not increase above ZAR�raised her speed characteristics when driving, for example, amphibious ship, is only used when the pushing power of a propeller in a ring, and in the use and availability of other auxiliary devices of the vessel. This is due to the resistance to the motion of the vessel through the water, which leads to loss of traction. Thus, it is not always possible to increase the speed of the vessel due to the limited resource of the application and does not allow the development of high speeds, i.e. out of range of screen effect. The disadvantage is the lack of additional means of creating mover behind a dense veil of the atmosphere in the form of misty clouds, mixing different mediums of air, the density of the atmosphere which must be increased, which reduces its speed performance in General. The jet of exhaust air to the atmosphere from the annular nozzle does not meet the "curtain wall" of a more dense composition of the atmosphere at the rear of the vessel, and is not created additional opportunities - repulsion of the vessel in the direction that reduces draught of the vessel in General.

Usually a jet of air from the propellers used for gauge pressure at the bottom of the ship that at low speeds provides aerodynamic unloading and reducing the draught of the vessel. For the proposed invention is somewhat different distinctive formulation of the problem.

It is known that di�station movement or rise depends on design features and purpose of different vessels: their parameter hydrodynamic resistance, etc.

It is known that amphibian hovercraft, comprising a housing with a flexible air-cushion, includes side lower balloons, front and rear flexible elements and rigid boards, engine, propulsion and injection setup with the drive mechanism in the form of a pusher propeller in a ring, in which the air screw is rigidly fixed frame, and the control system, inflatable Board, mounted on a rigid hull sides around the perimeter of the vessel (patent RU 2349475, CL B60V 3/08, 2008).

The disadvantage of this amphibious air-cushion vessel is its limited speed characteristic in the movement, as the propulsion of the vessel is made only in the form of a pusher propeller, placed in a ring in which for the air screw is rigidly fixed frame, and set the horizontal and vertical aerodynamic rudders. Injection setup is capable of receiving its torque power of the motor through V-belt transmission. In this regard, in the known invention was given a specific task - from overturning moment at high speed at the bow to enter on the axis of the hinge wing, made a split, and these parts are held in the center of the axis of rotation�Oia. However, as in prior art, to develop and to increase the speed of the propeller in the atmospheric environment in motion is not possible because of the need only the power of the engine, i.e. the engine torque, a limited resource in the manufacture.

The prior art discloses: amphibious hovercraft and ships snow type.

The technical result of the group of inventions is to provide, for example, the stability and improving the navigability afloat, including strong winds and waves. However, they also provided an additional way to use extra mover, and it is ineffective in comparison with the present invention in structure. All of them does not provide and does not account for a significant symptom as creating additional values to high density (curtain) of the atmosphere for a mover, there is no new technical solution proposed to create the effect in the movement of the ship as a whole.

The purpose of the invention - increase speed-thrust propulsion, maneuverability by improving the efficiency of mixing heterogeneous active medium during operation of the vessel.

According to the present invention this problem is solved due to the fact that in the hovercraft, comprising a housing with a flexible air-cushion,�luchshee side lower balloons, front and rear flexible member, and with hard sides, engine, propulsion and injection setup with the drive mechanism in the form of a pusher axial propeller fan in a ring, in which the propeller is rigidly fixed frame, and the control system, inflatable Board, mounted on a rigid hull sides around the perimeter of the vessel, the annular nozzle is further provided with a rigid frame, coaxially to the annular nozzle from the outer surface, and an additional frame is provided with rigid legs and placed them on the shaft of the swirler source of the active medium in the form of a turbine, made ventrodistal, secured to the shaft axis with the reflector and a fixed axial movement relative to the rotor, wherein the profile of the turbine ventrodistal defined as the minimum constant small radius relative to the axis of the propeller fan.

In addition, the turbine intoleranta made with the possibility of axial movement coaxially relative to the pressure inlet conduit with an active nozzle from the axis of the propeller.

In addition, the discharge pipe is freely passed through the Central part of the inside axial propeller and is connected by flexible tubing to a source of the active medium with the compressor.

In addition to t�, on embodiment it contains the active nozzle with an annular protrusion on the outer surface, and a reflector in longitudinal section is located to the symmetry axis of the turbine ventrodistal angle to each other equal to 40-80°.

In addition, according to embodiment of the additional frame is equipped in the upper part along the perimeter of the annular hollow horse pipe with holes, placed vertically telescopic pipe - source active environment - with the possibility of movement relative to a fixed swirler in the form of a fixed impeller on the shaft, and a telescopic tube has an output end provided with a nozzle facing the impeller, and a hollow tube connected by a flexible tube to a source of the active medium, manoeuvring which is produced from the control panel.

The applicant has not identified technical solutions, identical to the claimed invention, which allows to make a conclusion about its compliance with the criterion of "Novelty."

The implementation of the distinguishing features of the invention leads to the emergence of important new properties of the object: the turbulence flow of air driven propeller blades, in this case via the inlet duct, the air passing through the nozzle, the pressure on the conical turbine blades vincolato, the flow of the active medium Pref�dit rotation, in addition, at the same time air stream from the rotor blades additionally has an impact on the rotation of the turbine ventrodistal with reflector. Thus, from the turbine ventrodistal (small dimensions relative to the geometric dimensions of the drive of the propeller), you receive the response to the active medium in the form of compressed air (or steam under high pressure), which turbulized the flow of compressed air received mezhlopastnye compartments as a result of impingement on the reflector. Additional compressed air (or steam high pressure) continues to mix with the air mass from the drive of the propeller. Thus, additional jet inlet air (or steam) at high speed revolving along the inner periphery of the reflector facing to the zone for the drive of the propeller. As a result of common mixing zone is formed with a higher density greater than the density of the atmosphere, i.e., a "hazy cloud". Thus, for a vessel receiving area of the veil with a high density, which increases the repulsive moment during the forward movement of the hovercraft. Hence, as is the formation of additional reactive power, contributing to the increasing speed of the vessel through the water (obtained additional STRs�about propulsion of the vessel).

It should be noted also another important factor that the powerful drive of the propeller there is a suction effect of the active medium of the fluid upstream of the turbine ventrodistal and then the nozzle pressure pipe works in the form of a pump, where the air is coming from your receiver, connected to the compressor, goes at high speed. In this case, by creating a vacuum compressor can be turned off, the process is automatic, until it is deactivated with the remote control (not shown in the figure for simplification). The reflector at the end of the turbine ventrodistal right angle (variant of execution can be different, Fig. 2) to the radial direction in the direction of drive of the propeller tends to direct the received additional compressed air is mixed with the air screw and behind it, creates a veil of misty clouds. Density higher than the density of the atmosphere. Thus, there is an increase in high-speed main thrust of the propeller, even at short-term actuation of the active medium in the form of additional air (or steam) from the control panel.

The speed of rotation of the small conical turbine ventrodistal and the intensity of mixing heterogeneous active medium (air or vapor) depends on the arrangement and design of the reflector to the radial direction and the distance from the axis of the turbine.

�maximum turbine rotation speed ventrodistal with blades, when the process flow of the active medium of the air receiver is under pressure from the compressor and the rotational speed of the main drive of the propeller, i.e. when you create the energy of the air circulation in front of the turbine ventrodistal.

The stability of the turbine in a horizontal plane in front of the nozzle inlet pipeline, passing freely through the Central portion of the inside of an axial fan, is provided by supports fixed at one end rigidly to the frame is rectangular, and the axial load reactive power of the active medium is perceived by fastening the reflector to the axis of rotation with radial rays fastening, made in the form of supports.

In addition, according to embodiment, it contains the impeller on the shaft, the telescopic nozzle with an outlet nozzle and an annular hollow pipe, which is attached to the vertical pipes. An annular pipe connected to the source of the active medium of air (vapor) from your receiver, connected to the compressor. Control is from the control panel (not shown), for example, the flow of the active medium.

Thus, the interaction of the propeller with the veil denser mass creates a torque that accelerates the movement of the vessel. An additional thrust from the propeller. Since the density of the veil (hazy clouds) increases significantly enough, Uwe�icepets and speed of the vessel, overcoming resistance through the water, consequently reducing the distance and travel time for the arrival of the vessel at the destination course. The ratio of excess consumption additional air (steam)is determined from the dynamic characteristics of the jet apparatus, impact of jet on vane with getting active medium, mixed with an air stream, exerting little influence on the drive of the propeller, since the location behind him at some distance the nozzle is connected with the turbine ventrodistal (form design) with reflector. The compressor may be briefly disabled and then the moment comes in the form of ejected pump from rotating turbine ventrodistal, the speed of which will depend on air circulation flux produced by the drive of the propeller.

The applicant has not identified any sources of information that would include information about the impact of the distinctive features of invention technical result. Above allows, according to the applicant, to make a conclusion about conformity of the proposed technical solution the criterion of "inventive step".

The invention is illustrated by drawings, where shown:

Fig. 1 shows a diagram of the General arrangement of the vessel (engine not shown);

Fig. 2 and�OBrien node mover, an embodiment of the active nozzle and the shape of the reflector with the actuator;

Fig. 3 shows the Assembly of the propeller, an embodiment of a telescopic tube - liquid and the impeller wheel.

Hovercraft includes a housing 1, libkovice side lower balloons 2, the fore end 3 of the vessel, the aft end 4 of the vessel, the bow (front) a flexible enclosure VP, stern (rear) a flexible enclosure VP, removable awning. Injection setup is described in the specific example at the same time and the engine 5 of the vessel. Inflatable Board, the Central skeg, protectors, line connection sections of the body, screw drive units contains (main fan) 5, vertical wheel 7, a rectangular frame 9. Propulsion vessel 5 is made in the form of air vent screw type in the annular nozzle 8 for the air screw, which establishes the vertical and horizontal aerodynamic rudders.

The housing of the nozzle has an annular extension, the extension of which is a rectangular frame 10, on which two supports 11, 12 is mounted a drive shaft 13 (axis) with sleeve 14 on the front console which is fixed to the reflector 15, and attached to it a conical turbine 16 intoleranta with blades 17. The output end of the discharge pipe 18 and a nozzle 19 is located in front of the conical turbine 16 winthrops�Noah, and the inlet end of the discharge pipe 18 is freely passed through the Central portion 20 in the axial propeller 5 and has a rigid connection with a flexible tube 21 to a source of the active medium from the receiver 22 to compressor 23. The body of the annular nozzle 8 serves for venting to the atmosphere, wherein it is mixed with the active medium is air, or steam coming under great pressure, due to the presence of the turbine 16 with a reflector 15 in the form of the veil, the density of which is higher than the density of the atmosphere. The axis of the drive shaft 13 is located in the same plane with the corresponding internal axial line of the propeller 5 with the discharge conduit 18 and the supports 11 and 12 with the guide 24 eliminates the possibility of misalignment of the conical turbine 16 ventrodistal. The variant changes of the reflector 25 on the profile shape and the active nozzle 19 with a conical protrusion 26 on the outer surface (Fig. 2).

An embodiment of Fig. 3 involves the installation of a hollow horse ring pipe 27 located on an external surface of the frame 10 with the tubes 28, and the telescopic nozzles 29. Telescopic nozzles 29 are of the nozzle 30 is directed to the center of the impeller 31, the shape of the profile which is assigned constructively in the design of a device with a small radius, respectively in comparison of the ratio with axial propeller 5. Telescope�cal pipe 29 with the nozzle 30 is mounted for movement relative to the inlet tube 28 of the channel messages with horse tube 27, communicated with a source 22 of the active medium of air (pair) with the compressor 23 (connection not shown). All the elements are removable and interchangeable to adjust. Construction of additional node of the propeller depends on the design of the reflector 15, 25, ℓ2 distance to the radial direction to the turbine 16 and the distance ℓ1 from the axis of the turbine to the nozzle 19 of the pipe 18.

Operation of the hovercraft is as follows.

To operate the vessel include injection plant (not shown), creating a lifting force. At the same time the rest of the air is discharged horizontally into the atmosphere, this creates a driving force. The ship breaks away from the support surface and begins to move forward. To rotate the ship using the steering device.

When the vessel is on the water compressor 23 supply compressed air (steam) from the source 22 of the active medium along the flowline 18. Passing through the Central portion 20 in the axial propeller 5, the flow of the active medium exerts pressure on the blades 17 of the conical turbine 16 ventrodistal, leads her into the rotation, in addition, simultaneously, the air flow behind the fan coming from the axis of the propeller 5, and also generates the rotation of the turbine 16. There is an acceleration of rotation of the turbine 16 ventrodistal together � reflector 15 (25), which is fastened to the shaft 13 with the guide rails 24, overcoming the resistance to rotation of the reflector 15 (25). The flow of air (vapor) coming from the receiver 22, separated by the blades 17 of the turbine 15 into many equal parts of the streams flowing into mezhlopastnye compartments, and vented to the atmosphere, this creates a driving force. The ship dramatically accelerates its movement. Under the pressure of compressed air (vapor) in the delivery pipe 18 and with the addition of air from the axial air screw 5 conical turbine 17 intoleranta accelerates the rotation, the torque increases, turbulized flow and the jet of an obstacle in the form of the reflector 15 (25), is atomized and mixed with air coming from an air screw, thereby forming a veil in the form of "misty clouds". As a result, the reflector is also formed by reactive zone of circulation, which continues the process of intensive mixing of the active medium along the periphery of the additional frame 10. Thus, there is a process of continuous and intensive mixing of compressed air (or high pressure steam). As a result, axial propeller in the atmosphere creates a veil in the form of "misty clouds", with greater density than the atmosphere itself. The rigid coupling of the turbine 16 with a reflector 15 (25) provides synchronous operation in the atmosphere when the motion�research Institute of the vessel. The speed of rotation of the conical turbine 16 ventrodistal and intensity of impact of the jets of the active medium on the reflector 15 (25) with the General mixing of air may depend on the connection of all elements to devices that generate maximum speed from the discharge pipe 18 and a nozzle 19, and the speed of axial rotation of the propeller 5, which increases the efficiency of the vessel in transit.

It should be noted, that the formation of a zone of reduced pressure around the nozzle 19 at the end of the discharge pipe 18 may be further continuation of the suction jet of compressed air (vapor) in the rotational motion of the turbine 16 ventrodistal due to the increased influence of air from the rotational axis of the propeller 5, i.e., increases torque to the drive shaft 13 in the bearings 11, 12 which ensure the sustainability of the turbine 16 with a reflector 15 (25) when the axial load. The compressor 23 is turned off.

The action of rotation of the turbine 16 with a reflector 15 (25), the latter may be of any shape (rectangular, conical, semi-circular, etc.) located at the axial end of the rotor 5 relative to the last so there may be little in dimensions, these design elements have no visible impact (resistance) to the rotation of the blades in about�the left air screw 5, consequently, the conditions that dramatically increase the speed of movement of the vessel due to the curtain formed a dense mass with respect to the atmosphere, i.e. the additional mover increases traction of the vessel in motion not less than twice in a big way.

According to the embodiment of Fig. 3 due to the possible harmonization of the structures in the operating position of the hollow pipe 27 with a flexible line (not shown) connected to the pressure line of the compressor 23 to a source 22 of the active medium. Air or steam under high pressure out of the nozzles 30, always in contact with the impeller 31, mixing with atmospheric air, next, a veil, the density of which is higher than the density of the atmosphere outside the aircraft in the short interval of acceleration of the water, reducing the distance and travel time, and little will depend on natural conditions, but rather under conditions of clear calm weather. The ship additionally in such cases, it is "masking" in motion because of the resulting cloud of mist behind him, at high speed vessel, the scope is quite wide, for example, in military AVM, etc.

The effectiveness of the proposed device uses a method of increasing traction of a hovercraft in the implementation of technological schemes when moving on water or snow.

Offer to�instrukciya new element in the present invention does not require large expenditures for the respective small geometries. Turbine intoleranta performed respectively with different optimal sizes relative to the linear dimensions of the axial propeller, has an optimal point of operation mode of the turbine ventrodistal with a reflector, which can also have any shape of its manufacture.

Due to the small dynamic resistance of the circuit turbine ventrodistal with the reflector in the area of the Central portion in line with the drive of the propeller loop resistance of the device a little because of the vacuum in this area, based on the dynamic load of the propeller according to its geometric dimensions. The flow rate is distributed by the ratio of the presence mezhlopastnye space in the turbine 16, wherein the thread organized by spraying the active medium when hitting the reflector, creates confusion in the area of additional rectangular frame, improving the speed characteristics of the propeller and the propeller can be used as an additional source of propulsive power of the vehicle afloat or on snow. In addition, the design of the system nodes is simple and mover provides a way to create curtains denser mass than the atmosphere, which increases the axial thrust of the propeller when the vessel, wherein the payload of the vessel increases, the mass and maneuverability way� improve the efficiency of mixing heterogeneous active medium when the vessel is on water or on snow. Thus, the integration in a single technological cycle of optimal design solutions and create a veil with the increased density of air or steam mixed with air received from the air screw at the rear of the ship in motion. The ship is made industrially by conventional equipment known and constructive materials with the proposed additional propulsion unit that determines, according to the applicant, his criterion of "industrial applicability".
