Utility models known in the description should be cited (Patent RU No. 191366, B60F 3/00 dated 02.08.2019; patent RU No. 190540, B60F 3/00 dated 03.07.2019; patent RU No. 147473, B60 3/00, B62M 27/00 2014), which are characterized by technical solutions by common features to patenting the above described similar technical solution, therefore, due to the reduction of the description, these aggregate essential features are not disclosed in the proposed description of the invention.

An aerosled (PM RU # 191045, B62M dated 02/01/2019) was chosen as a prototype of the invention, the general features of the technical solution and prototype proposed for patenting are:

- ski boat;

- a cabin installed on shock-absorbing suspensions made in the form of pneumatic suspensions and fixed with their lower ones on the corresponding sections of the upper surface of the boat-ski, and with their upper surfaces on the corresponding sections of the lower surface of the cabin;

- internal combustion engine;

- a gas tank located at the rear of the cab;

- a gasoline pump located in the rear of the cabin and connected by its input to the inner cavity (outlet)) of the gas tank and by its output to the input of the internal combustion engine;

- a starter located with its outlets to the fuel spark plug in an internal combustion engine;

- a battery located inside the cab and connected by its negative terminal directly and by its positive terminal through the first switch to the supply inputs of the fuel pump, and through the second switch to the supply terminals of the starter of the internal combustion engine;

- control panel with switches installed on its front part of the panel, located in the front part of the snowmobile.

The main disadvantages of the known devices, like the prototype, is the fact that the presence of an internal combustion engine in the aft part of the ski boat is equipped with a bulky propeller, which greatly complicates the design and takes up a large place of the ski boat, increases its weight, in particular, in the area rear (aft). The use of an additional compressor with feeding elements and other fittings in this device also makes them difficult, due to their low efficiency and filling the production of a separate compressor of compressed air for small filling of air bags on the left and right of the ski boat, therefore, complicates the control scheme of the directly feeding air ... In addition, all these devices require special fastening places in the cabin (cluttering up its free space), as a result of which commensurate space is required for the compressor in the cabin (various noises are created that affect the crew in operation). In this case, the tractive effort is directly related to the large air propeller, fixed from above in the area of the rear (at the stern), which complicates its operation and injury from the side open from the internal combustion engine. All this as a whole worsens the aerodynamics of the snowmobile (air mass flow in motion), and also worsens the performance, while there is no possibility of using, for example, a propulsion device with an impeller on a ski boat in the form of a blower in compressor mode, as well as depending on operating conditions the possibility of an additional angle of rotation up to 360 ° with the help of a rudder shield located outside relative to the rear of the stern for the central longitudinal air pipe-redan above the flat bottom of the ski boat, the end of which has an expanding longitudinal channel with a bottom in the form of a confuser, its bottom is made flat surface in the shape of the bottom of the boat-ski and slightly higher, respectively, of the bottom of the boat-ski, allowing not to resist the bottom of the boat-ski in motion. In addition, such a connection of the rudder shield from the outside of the rear part (stern) under the U-shaped visor provides, additionally or simultaneously and synchronously with the operation of the airbags, the turn of the boat-ski to a steeper angle of rotation (up to 360 °) as a whole. At the same time, it allows to increase the braking of the boat-ski movement (to regulate), and also will increase the possibility of controllability, both by the traction force of the boat-ski, and the speed of filling the air bags with compressed air on the left and right sides of the boat-ski. The area of the additional rudder shield is chosen so that it can be used when driving on water, land, snow, etc. tractive force, better maneuverability in hard-to-reach places for various, for example, in search and rescue work, patrol services.

When using a small impeller operating in a closed housing, in the front (bow), for complete safety of its operation from the ingress of unnecessary flying birds and other objects, for the person serving the snowmobile, it is envisaged to install a mesh protective casing made of light aluminum alloy or durable plastic, like itself housing for the impeller, around the circumference of the vicious circle.

The objective of the claimed invention is to ensure simplicity and manufacturability of the design with the achievement of better operational capabilities and in expanding the arsenal of technical means that realize their purpose and use of compressed air from the impeller, as well as the possibility of their practical implementation in the form of a snowmobile. In this regard, given its purpose, described above, in the form of a snowmobile, is relevant today.

The technical result indicated above is achieved by the fact that a snowmobile containing a boat-ski, a cabin mounted on shock-absorbing elements made in the form of airbags, fixed with their lower surfaces on the corresponding sections of the upper surfaces of the boat-ski and their upper surfaces on the corresponding sections of the lower surface cabin bodies, an internal combustion engine and a propeller attached to the end of an internal combustion engine, a gas tank, a gas pump located near the internal combustion engine, a starter connected with its output to the input of an internal combustion engine, a starter connected by its outputs to a fuel spark plug in an internal combustion engine , and a battery located inside the cab and connected by its negative terminal directly to its positive terminals through the first switch to the fuel pump supply inputs, and through the second switch to the corresponding starter terminals, while the snowmobile is equipped with with a compressor connected at one end with a powered input directly and its other end with a powered input through the third switch to the battery terminals, with its first output through the first controlled key to the inner cavities of the air bags located on the left side of the ski boat and its other second output through the second controlled key to the inner cavities of the air bags, located on the right side of the ski boat, and the control circuit connected by its first feeding input directly and its second feeding input through the fourth switch to the battery terminals, its third input to the output of the reference signal source, its first output to the control input the first control key and its second output to the control input of the second control key, according to the proposed invention, the ski boat is made as a vehicle on a pneumatic flow, and a low-power impeller is used as a propeller in the form of a pressure device in the mode compressor, and creates an air stream at the end of the stern part of the ski boat above its flat bottom, the side inner walls of the ski boat, which are fixed to each other with a fastener, in the central part of the ski boat mount, a longitudinal air tube-redan is fixed to the bottom of it along the entire length of the ski boat, the end of the air pipe-redan, which has a transitional expanding section of the longitudinal channel with a flat bottom surface in the form of a confuser, the bottom of which repeats the shape of the bottom of the ski boat, while the air pipe-redan, fixed on the surface of the boat bottom- skis, allows you not to resist the bottom of the boat-ski in motion, and the nozzle of the small impeller in the area of the bow is connected with its outlet end with compressed air directly to the inlet of the air pipe-redan, in addition, the impeller nozzle with its side walls is connected through the tubes of the left and right with control keys with a cavity of airbags located on the left side of the redan pipe and on the right side of the pipe-redan, and the control scheme of the crew.

In addition, by filling each individual left and right air bag, it is a source of high-pressure air that can be filled from the impeller and safe for humans.

In addition, a low-power impeller is made in the bow of the ski boat in front in a closed hull next to the cabin at an appropriate height from the bottom of the ski boat and at an angle in the direction of travel.

In addition, the outlet end of the air pipe-redan in the aft part, made in the form of a confuser, is additionally equipped with a flap with the possibility of turning it around its vertical axis at an angle of 90 ° to each side of the air bag to the left or right from a mechanical transmission in the form of a thrust of the limiting angle of rotation, and, the thrust is connected to the steering column of the crew.

In addition, to brake a ski boat in the absence of an impeller thrust, a fixed U-shaped inclined visor with the possibility of vertical rotation using a lever fixed to the steering column by one of its ends is installed in the area of the rear part of the ski boat and behind the additional rudder shield ...

In addition, the front of the impeller is covered with a protective grill made of aluminum frame or durable plastic, and the impeller housing on the cab side is made of aluminum material or high pressure plastic.

In addition, the bottom of the air bags for a ski boat can be made of a composite material, and the side walls are made of a durable flexible material.

Analysis of the known snowmobiles with the proposed new elements allows us to conclude that there are no signs in them that are similar to the distinctive features of the claimed device, which corresponds to the criterion of "inventive step".

In this case, the snowmobile is located on the surface of the snow cover while increasing the stability of the vehicle, creates freedom of operation of the impeller for the hull with low power and in the direction of rotation, both with a mechanical rudder and with a change in the filling of compressed air from the impeller to the left or to the right airbag ski boats, while the central longitudinal air tube-redan allows you to stabilize the flow of outgoing air and thereby improve the performance of the snowmobile due to the reactive force of the jet coming out of the converger bottom expanding with a flat surface, the bottom of which repeats the flat shape of the bottom of the ski boat, and it also provides a decrease in the immersion of the rear part (stern) of the boat-ski when driving in deep snow with a significant increase in speed and adjusts the turn to a steep angle of the boat-ski, which means it also allows the whole structure of the device to glide smoothly on the water surface, snow, swampy terrain and others at service ovii observance of the speed limit, in particular during search and rescue work, patrol services, for the transport of goods and passengers to hard-to-reach places.

It should be noted that the impeller is driven by a gearbox with a stator and a rotor.

- at the end of the stern part of the boat-ski, it is advisable to fix a horizontal flow-directing element made in the form of a U-shaped visor - 28 with an inclination, which provides air lifting upward, as well as braking the snowmobile, located in the area of the rear part (stern) of the ski boat and controlled from by means of a lever, fixed at one of its ends on the steering column - 20. In this case, the lever is not indicated in the drawings;

- cabin - 8 inside provides lighting in the form of a light-emitting element from a battery source - 17 direct current with a voltage of 0.96 V to 12 V, having a brightness sufficient to form a color-dynamic composition, the optical effect of which will be even stronger in the evening or at night ... Changing the color gamut of light emission is carried out by a programmable controller with color-dynamic programs embedded in it, which automatically or from the control panel (the connection diagram is not shown for simplicity, since it is not included in the description of the invention), by means of compiled algorithms and, after a certain period of time, produces change of the color dynamic composition in the interior of the cabin - 8. In this case, the light-emitting element is not indicated in the drawings.

The proposed snowmobiles are operated as follows.

The driver (crew) is located at the steering column - 20 and checks the presence and value of the output voltage of the battery - 17, as well as the presence and amount of fuel in the gas tank - 14.

After that, using the third switch - 22, it supplies the output voltage of the battery - 17 to the inputs of the nozzle - 4 of the impeller - 5 (Fig. 5), which is filled with compressed air and creates at its outputs (first and second) streams of compressed air from the operating impeller - 5 and through open controllable keys -23 and 24 directs to the internal cavities of the airbags 9, 10, 11, 12, the compressed air pressure in which is controlled by sensors (the pressure sensors are not shown in the figures of the drawings).

Simultaneously with these, with the help of the fourth switch - 26 (Fig. 5), the output voltage of the battery - 17 is supplied, to the supply inputs - 1 and 2 of the circuit - 25 control, which, under the action of the reference signals coming from the output of the source - 27 reference signals to it the third input, the program recorded in the permanent memory (ROM) and signals coming from the outputs of the compressed air pressure sensors inside the airbags - 9, 10, 11, 12, control signals are generated and when the set value of the compressed air inside the airbags is reached - 9, 10, 11, 12 from the first and second inputs of the control circuit - 25 to the control inputs of the first - 23 and second - 24 controlled keys, control signals are received and the controlled keys - 23 and - 4 are closed, thus stopping the supply of compressed air from the nozzle - 4, connected with the operation of the small impeller - 5, into the inner cavities of the airbags.

Compressed air filling the cavities of the pneumatic bags - 9, 10, 11, 12 is carried out simultaneously with the operation of the nozzle - 4 from the impeller - 5, supplying a given volume of compressed air directly and into the longitudinal air pipe-redan - 3, i.e. in one cost-effective interface. This is generally related to the operation of the internal combustion engine - 13, when the output voltage of the battery - 17 is supplied through the first switch - 18 and directly to the supply inputs - 1 and 2 of the gasoline pump - 15 (Fig. 5), which supplies fuel from the gas tank - 14 at the engine input - 13 internal combustion.

At the same time, the output voltage of the battery - 17 (Fig. 6) is supplied through the second switch - 19 and directly to the supply inputs - 1 and 2 of the starter - 16 and to the terminals of the fuel spark plug in the internal combustion engine - 13.

The internal combustion engine - 13 is triggered and rotates the propeller with blades in the form of an impeller - 5, thus creating a lot of pressure and thrust through the nozzle - 4 into the redan pipe - 3 with an expanding transition section in the form of a closed confuser - 6 longitudinal thrust for the movement of snowmobiles, due to the fact that the rotation of the impeller blades is 5, and the compressed air pressure is directed towards the nozzle - 4, connected to the redan pipe - 3 and with an expanding section with a flat bottom in the form of a closed confuser - 6, and an outlet from the rear snowmobile ski boats. The air flow creates an increased traction force of the exit from the rear of the snowmobile from the side of the steering shield attachment - 7 after the confuser - 6, since all the air enters it and is thrown into the atmosphere, the snowmobile begins its movement on the surface of the water, snow, etc.

If it is necessary to turn the snowmobile to the right or to the left and to a sharp turn 360 °, along the course of movement in the circuit - 25 control under the action of task signals coming to the third input of the circuit - 25 control, the program recorded in the ROM and signals coming from the outputs of the compressed pressure sensors air inside the airbags - 9, 10, 11, 12, corresponding control signals are formed, which, when the snowmobile turns to the left, go to the control input of the first control key - 23, which opens the flow of additional compressed air from the nozzle - 4 impellers - 5 into the inner cavities of the airbags - 9 and 10, increasing its volume and, accordingly, ensuring the left turn of the snowmobile. However, this is still not enough for a sharp turn of the snowmobile (bypassing steep obstacles, etc.), therefore, the rudder shield - 7 is additionally used to turn 360 ° at a given angle for the left turn of the snowmobile, creating better maneuverability of the snowmobile on the surface of water, snow, lakes, ponds, reservoirs, rivers, etc. - this is important for maintaining stability due to the shape of a snowmobile with a flat bottom on pneumatic cushions.

When the snowmobile turns to the right, the control input of the second controllable key - 24 provides the receipt of the generated corresponding signals by the control circuit - 25, which open the flow of additional compressed air from the nozzle - 4 impellers - 5 into the internal cavities of the pneumatic bags - 11 and 12, increasing its volume and accordingly ensuring the right turn of the snowmobile. However, this is not enough to create a sharp 360 ° turn in the direction of travel, so they use the rudder flap -7 and also turn it at a given angle for the right turn of the snowmobile, creating better maneuverability of the snowmobile on the surface of water, snow, lakes, ponds, reservoirs, rivers etc. - this is important for maintaining stability due to the shape of the flat-bottomed snowmobile.

After completing the turn to the right or left at any steep angle, the control signals from the control inputs of the first - 23 and the second - 24 controlled keys are removed and compressed air does not enter the internal cavities, and the rudder flap - 7 is installed in the middle part of the extension of the longitudinal axis of the confuser - 6.

To switch from maximum movement to movement to low speed snowmobiles, the engine speed with a small impeller is reduced - 5, and at the same time the rudder flap - 7 controlled by a lever attached to the steering column - 20 turn one of their ends and close the confuser space - 6, occurs braking, when the U-shaped visor - 28 is used at the same time, installed obliquely in the rear part behind the steering wheel shield - 7 of the ski boat and also controlled by a lever attached to the steering column - 20 by one of its ends.

To align the normal position of the snowmobiles and their movement, in the control scheme - 25, special signals are generated that are fed to the corresponding actuators, which ensure the operation of the corresponding safety valves, communicating with their inputs with the internal cavities of the pneumatic bags - 9, 10, 11, 12, and their outlets with atmosphere, as well as the steering wheel flap itself, is simultaneously controlled - 7. At the same time, the safety valves and actuators are not shown in the figures.

In this case, the cabin - 8 inside is equipped with a light-emitting element (not shown), the power of which is carried out by an alternative energy source, in this case from a battery - 17. With the help of a controller (not shown) integrated into the circuit of the light-emitting element, with embedded color-dynamic programs automatically or in manual mode, through the remote control, the color-dynamic composition is changed in the inner space and through the glass of the cabin - this reflection is transmitted to the open space outside when the snowmobile is moving or parked. This additionally, both inside the cabin and outside it into space, gives light emission to the surrounding nature and safety, especially in the evening and at night.

It should be noted that the bottom can also be made of composite material or other similar materials for the air bags of a ski boat, for example, light durable plastic in the middle part, and the side walls of the skin are assembled and fixed from a strong flexible material, which protects the bottom from fast abrasion on a hard surface in the motion of the snowmobile. In addition, the front of the impeller is covered with a protective grill made of aluminum frame or durable plastic, and the impeller housing on the cab side is made of aluminum material or high pressure plastic.

Thanks to the new design of the proposed invention and the placement of a small impeller in the front part of the (bow) snowmobile, the whole mode of their movement changes as a whole, while the speed will be higher due to the outgoing reactive force of the air stream into the atmosphere from the confuser - 6, which leads to fuel economy in several times more. In addition, in the proposed design - a snowmobile, there is no need for a complex application of a compressor and a propeller in the end part (stern) of a ski boat, which means that the weight is sharply reduced in general. Also, the proposed snowmobiles have increased maneuverability and versatility, for example, they allow you to turn at an angle relative to the turn of the snowmobile at an angle greater than that of the prototype from the neutral position, turning the rudder flap at an angle of 90 ° to the oncoming air flow coming out of the confuser behind the stern of the ski boat ...

The proposed snowmobile, in comparison with the prototype, is simple in design, has a high rate of maneuverability and maneuverability, is stable in the horizontal and vertical plane, transportable, in addition, it allows you to expand the range of application of the snowmobile for practical implementation on compressed air by using a small impeller with specific conditions on water, snow, swamps, lakes, reservoirs, rivers, and creating an increase in the movement of snowmobiles with a constant power of the internal combustion engine compared to the prototype.
