The invention relates to a transport machine-building, specifically for amphibians with rotary-screw propulsion.

A known way of a rotary screw amphibian on land, at which amphibians set the trim to the stern through the device, which includes installed in the bow of the special wodoslawsky tank and legionarie brackets [1].

The disadvantages of such devices and, accordingly, the method should be attributed as nonoptimality of the mode of movement afloat and nonoptimality of landfall.

The closest in purpose and essential features of the claimed method is a method of the output rotary screw amphibian on land, including pumping water from the front along the cavities of the rotor propulsion before landfall and pumping the remaining water in cavities after the release of the amphibian on land [2].

For amphibians characterized by three basic States:

movement afloat without trim when filled with sea water the front and rear cavities of the rotor sections rotors);

the spines of the rotors (sections rotors);

movement on land with empty front and rear cavities of the rotor sections of the rotors).

The closest in purpose and essential structural features of the claimed device is amphibious to implement the above method, comprising a housing, a rotary-screw propulsion with front and rear cavities of the rotor (in this case, the cavities of the front and rear sections of the rotors, respectively) and the hydraulic system with intake and discharge lines, informing mentioned cavity with the ends of the intake and discharge of highways [2].

However, the known device is not quite perfectly, because in the process of entering the amphibian on land interaction of the front parts (sections) of the rotors with the ground (soil, sand, ice, snow, and so on) is characterized by a relatively small hitch weight that caused not only by the angle of attack (pitch amphibians on the stern, but the emptiness of the front cavities of the rotor. Moreover, the presence of water in the rear cavities still "hanging" in the water, not interacting with the ground of the rear parts (sections) of the rotors causes additional resistance to movement (the effect of "wet tail"). In the result of adhesion forces may be insufficient for successful entry amatuzio: under certain combinations of the coast relief (primarily when a gentle slope) and the geometry of amphibians increased weight of the rear part (section) of the rotor will facilitate the grip of the rear part (section) of the underwater part of the ground.

The problem to which the invention is directed in part way, is the improvement of technical and operational characteristics of amphibians, namely facilitating independent access from the water to the land.

The solution of the stated problem is achieved in that in the way, including pumping water from the front along the cavities of the rotor propulsion before landfall and pumping the remaining water in cavities after the release of the amphibian on land, at partial output of the rotors of the water from their land back during the cavities pumped and simultaneously pumped in the front along the cavity.

The task is also solved by a method of the aforementioned characteristics at partial output rotors on land water from the rear along the cavities can pump in the front along the cavity.

In principle, the implementation of the inventive method is possible using the known device the prototype [2].

However, first, outboard intake may already be fully or partially impossible, secondly, sabarth, work is on-Board pumping station requires high energy consumption.

The implementation of the declared method with additional characteristics (pumping water directly from one cavity to another, i.e., "offline") through the hydraulic system of the amphibian prototype [2] is impossible.

Both claimed process (primary and secondary) can be carried out due to the fact that the device, comprising a housing, a rotary-screw propulsion, at least with front and rear cavities of the rotor and the hydraulic system with intake and discharge lines, informing mentioned cavity with the ends of the intake and discharge lines, the hydraulic system provided with a device for pumping water between the front and rear cavities of the rotors.

Among identified patent and literature search methods and devices not discovered such a set of essential features which would coincide with the set of essential features of the claimed method and device for its implementation.

At the same time, it proposed a set of features is necessary and sufficient to solve the problem. When this feature "from the back... of the cavity is pumped into the front..hence, and declared a constructive sign, developmental (complementary) hydrosystem amphibians, providing the possibility of pumping water directly from one cavity to another, implements an additional way and eliminate with the above three lack of fresh water intake from the device prototype.

In Fig.1 schematically shows the position of the amphibious afloat; Fig.2 shows the first stage output of the amphibian on land, characterized by her job-pitch feed by pumping the front cavities; Fig.3 - the second stage is characterized by redistribution of weight onboard water to feed on the fore part; in Fig.4 - the third stage is characterized by pumping (discharge) the remaining side of the water; Fig.5 is an example of a hydro scheme in the products amphibians.

Amphibious contains the floating body 1, a rotary-screw propulsion in the form of each side, symmetrically installed rotors, each divided into two or more parts (sections 2 and 3 are insulated from each other cavities 4 and 5 and is provided with helical ridges 6 and 7, respectively (see Fig.1-4).

Cavity 4 and 5 are connected in series through the internal hydrosalinity 8 and 9 and the valves 10 and 11 soothram pumping section 14 of the pumping station 15, and the inlet section 14 is connected with the intake line 16, the other end of which is through an external hydrosaluric 17 communicates with the sea water 18. The pipe 12 is connected to the suction inlet suction section 19 of the station 15, and the inlet pipe section 19 is connected to the drain line 20, the other end of which communicates with the sea water 18 or with the surrounding space above the waterline amphibians.

In the cavities 4 and 5 are placed in the internal air inlets 21 and 22, respectively, which are connected with the surrounding space above the waterline with the formation of drainage systems cavities 4 and 5.

Items 8-22 together form a hydraulic system.

In the claimed amphibious hydraulic system further comprises a device (hydrological) pumping water from the cavities 5 in the cavity 4 or (optional) from the cavity 4 cavity 5 (additional hydrological shown in Fig.5 and conventionally in Fig.3). It includes two valve (three-way three-position spools with remote control) - 23 and 24, the pipes 25, 26 are connected with the cavity 4, and the pipes 27, 28, connected with the cavity 5. This uses existing pump station 15 pumping with especiauy pumping water only in the direction from the cavity 5 into the cavity 4 (if stated an additional way is not supposed to be back in amphibians).

Device (highway) 23-28 pumping water may also contain its own pump section of the pump station 15) with intake and discharge pipelines connecting through the said pump cavity 5 cavity 4 (figures not shown).

In the rest of the (internal intakes 8 and 9, the features of the valves 10 and 11 and so on) example of embodiment of the device corresponds to the device prototype and described in detail in the source [2].

The above design examples do not exclude other possible options within the stated essential structural features.

The claimed method of the output rotary screw amphibian on land as follows (the example output in forward motion).

With the approach of amphibians, floating with water-filled cavities 4, 5 (see Fig. 1), to the coast line or the edge of the ice (with sufficient bearing capacity and stability) set the trim to the stern, which produce simultaneously pumping water from the front of the cavity 4 (see Fig.2).

It is carried out (see Fig.5) by including a pumping section 19 of the pumping station 15 and the switching valve 10 to the right. is 1.

At partial output rotors on land water from the cavities 5 pump and simultaneously injected into the cavity 4 (see Fig.3).

It provides one of two possible ways.

By the first method the water from the cavity 5 pumped overboard. To do this, include (leaves included) section 19 of the stations 15 and translate the valve 11 in the right position. At the same time in the cavity 4 is injected outboard water include (leaving included) section 14 station 15 and moving the valve 10 in the leftmost position, i.e., connecting the cavity 4 to the pump section 14.

On the second way water from the cavities 5 is pumped directly into the cavity 4. To do this, in the neutral (middle) position of the valves 10, 11 valves 23, 24 synchronously transferred from the neutral (middle) to the left position.

Thus the low pressure pipeline 25 and the high pressure pipeline 26 is connected to section 14 station 15. The drainage of the air is similar to that described above.

Regardless of which of these two methods produce the redistribution of water in the cavities 4 and 5, is offset from the center of mass from the stern to the bow of the amphibians. This leads, on the flying boot and efficiency of the rotors as ground propulsion. On the other hand, this leads to a decrease in the resistance movement from submerged aft-defined component of gravity of the rear parts (sections) 3 rotors.

If the amphibian on land produce pumping water from the cavities 4 overboard. When the neutral (middle) position of the valves 23, 24 switch valve 10 to the right, thereby connecting the cavity 4 with working suction section 19 station 15.

The output of amphibians from water to land back similar to that described: rear cavity should be considered as the front and Vice versa, and valves to switch to the other side.

The use of the invention allows to improve technical and operational characteristics of amphibians, namely to facilitate self out of the water onto land due to rapid pumping of water (into the position of amphibians with trim at the stern of the rear cavities of the rotor propulsion in front of the cavity and thereby increase the coupling weight of the front parts (or sections) of the rotors with the edge of the land and at the same time weight reduction submerged rear parts (or sections) of the rotors.
