Abstract

The utility model relates to vehicles above the earth and water surface using the effect of an air cushion.

The present utility model is based on the solution of the problem of creating an air cushion apparatus that, when moving, would not come into contact with the surface of water or land, which will increase its speed and economy, ensure that high waves and unevenness of the land are overcome.

According to the utility model, this problem is solved due to the fact that in an air-cushion vessel, including a hull with an air-cushion chamber, a propulsion system installed in the bow of the vessel and a stabilizer in the stern connecting two keels, two wings are made on the sides with ailerons, and the stabilizer is equipped with a elevator.

AIRCRAFT BOAT

The utility model relates to vehicles above the earth and water surface using the effect of an air cushion.

Known means of transportation on an air cushion, containment, its body with air cushion chambers, a fan unit with a drive, placed in the aft part, air channels for supplying air from the fan unit, steering flaps and a flexible front wall of the air cushion chambers; the outlet openings of the air channels are spread, aeons in the aft part of the hull directly in front of the steering flaps, form; they rear wall of the continuation of the air channels, see SU ed. JVo499790 in class B60V1 / 18 dated 01/08/1970.

The disadvantage of this technical solution is the lack of stabilization by the angle of the trim, the low speed of mixing;

A hovercraft is known, including a corne with an air cushion chamber, a propulsion system, a stirring located in the bow of the apparatus, and a stabilizer in the stern that connects two keels, see RF patent for industrial design No. 43643 of 05.24.1993 .

This technical solution is taken as a prototype of the present utility model.

Its drawback is, in fact, contact with the surface of water or land, which reduces the speed of movement, especially in conditions of rough water surface and uneven land, increases fuel consumption.

The present utility model is based on the solution of the problem of creating an air cushion apparatus that, when moving, would not come into contact with the surface of water or land, which will increase its speed and economy, ensure that high waves and unevenness of the land are overcome.

According to the utility model, this problem is solved due to the fact that in an air-cushion vessel, including a hull with an air-cushion chamber, a propulsion system installed in the bow of the vessel and a stabilizer in the stern connecting two keels, two wings are made on the sides with ailerons, and the stabilizer is equipped

elevator.

The applicant does not know any information about technical solutions that are identical to the claimed noisy model, which allows us to conclude that it meets the criterion of “novelty.

The essence of the noble model is illustrated by drawings, which depict:

figure 1 - device in a longitudinal section;

in Fig.2 is a view of "A in Fig. 1;

in Fig.Z - section "BB in Fig.1;

The vessel includes a hull 1 with an airbag chamber 2, a propulsion and injection unit 3 located in the bow of the vessel, a stabilizer 4 connecting the keels 5 and 6 and equipped with a section elevator 7. The keels 5 and 6 are equipped with the same rudders 8. The air from the engine -pressure installation 3 into the chamber 2 passes through the opening 9. The chamber 2 is limited by the skegs 10 and 11, a flexible bow guard 12, a flexible aft guard 13 with a hole 14 and a corne 1. The ship is equipped with wings 15 and 16 with ailerons 17 and 18, respectively.

The device operates as follows. The air from the propulsion system 3 is partially supplied through the opening 9 into the chamber 2 of the air cushion, and partially (most) is released into the atmosphere. Upon reaching the calculated pressure value in chamber 2

the vessel rises above the surface and begins to move forward due to the reactive force arising from the release of air into the atmosphere. When a certain speed is reached, a dynamic air cushion occurs between the surface of the water or land and the wings 15 and 16 and other elements of the vessel, which causes it to detach to a considerable height equal to approximately half the length of the vessel. The movement of the vessel at this altitude is drained; aileron 17, 18 elevators 7 and rudders 8 are used.

At the same time, thanks to running in, the flexible barriers 12 and 13 are pressed against the body 1 against the flow, reducing aerodynamic drag.

To land the vessel, the air supply from installation 3 is reduced, the speed decreases and the vessel gradually approaches the surface, then moving like a vessel on a static air cushion until it stops.

The vessel is manufactured in the factory using conventional equipment and well-known structural materials, which determines, according to the applicant, its compliance with the criterion of “industrial applicability.
