Abstract

FIELD: transport.

SUBSTANCE: invention relates to air-cushion vehicles. The vehicle comprises a high pressure air blower under the flat bottom between the floats, which form a skirt. Skirt is two hollow oval-shaped or elliptical pipes looped at the waterline level and allowing evacuation. The long axes of elliptical or oval-shaped in plan pipes lie in a common longitudinal plane and may be parallel to each other or may lie on a common axis. A pin teeth equal increment system is installed on pipes, where a pneumatic chamber system is mounted with chamber internal diameter comparable with the outer diameter of the pipe. Pneumatic chambers are stacked along the diameter and fixed by pairs on the pin teeth.

EFFECT: achievement of unification and simplification of manufacturing technology and application of the hovercraft vehicle skirt.

Description

The invention relates to air-cushion vehicles.

Known hovercraft (air sled) / cm. US Pat. No. 2478502 (class B60V 1/04, B62B 15/00) dated 12/08/2010 / containing a high-pressure air blower under a flat bottom between the floats forming a skirt that holds air under the vehicle.

The float skirt of a well-known hovercraft is not unified, the technology of its manufacture and use (especially when replacing) is not cheap and simple, which limits the functionality of the hovercraft.

In order to unify and simplify the manufacturing and use technology of a hovercraft vehicle skirt in an hovercraft vehicle containing a high pressure air blower under the flat bottom between the floats forming the skirt holding the air under the vehicle, the skirt is two looped at the waterline level which can be evacuated, hollow pipes that are oval-shaped or ellipsoid in plan, long oval-shaped or ellipsoidal planes in the pipe plan a common longitudinal plane and be parallel to each other or may lie on a common axis on the tubes mounted system equal pitch pin teeth, in which the mounted system is pneumatic with an inner diameter commensurate with the outer diameter pipes, pneumatic stacked in diameter and are fixed pairwise knuckle on bobbin. Moreover, in the embodiment of the skirt with the long axes of oval-shaped or ellipsoidal pipes on the common axis, the small axes of the oval-shaped or ellipsoidal pipes do not necessarily lie in the same transverse plane.

The technical solution proposed by the invention is illustrated in FIG. 1 (the long axes of oval-shaped or ellipsoidal in terms of hollow pipes are parallel to each other / version 1 / and lie on a common axis / version 2 /), FIG. 2 (cross-section of a pipe with lugs and a pneumatic chamber).

The air-cushion vehicle of the invention comprises a high-pressure air blower under a flat bottom between the floats forming a skirt holding air under the vehicle.

At the same time, the skirt that holds the air pumped under the underbody of the vehicle consists of two water lines that are rolled at the O-O level and can be evacuated, hollow pipes oval or ellipsoid in plan 1; the long axes are oval-shaped or ellipsoidal in terms of pipes 1 lie in a common longitudinal plane and can be parallel to each other (see Fig. 1, version 1) or can lie on a common axis (see Fig. 1, version 2). On pipes 1 (see cross-section in Fig. 2), an equal pitch system of tars (2 and 3) is mounted, on which a system of pneumatic chambers 4 with an inner diameter comparable with the outer diameter D of the pipes 1 is mounted; pneumatic chambers 4 are folded in diameter and fixed in pairs by kinks on the spindles (2 and 3). Moreover, in the embodiment of the skirt with the long axes of oval-shaped or ellipsoidal pipes 1 on the common axis, the small axes of the oval-shaped or ellipsoidal pipes 1 do not necessarily lie in the same transverse plane.

The skirt-float of a well-known hovercraft selected by the prototype is replaced in the proposed technical solution with looped, vacuum-proof hollow pipes 1 with a pin system (2 and 3), on which the pneumatic chamber system 4 is easily mounted, which can be partially or fully replaced , for example, during puncture of part or all of the pneumatic chambers 4.

Oval-shaped or ellipsoidal in plan, hollow pipes 1 can be designed and executed, for example, by setting axes and holding technologically justified ratios between the major and minor axes.

The carrying capacity and buoyancy of an air-cushion vehicle with the proposed technical solution largely depends on the degree of evacuation of the looped tubes 1 and the air pressure in the pneumatic chambers 4, with other things being equal, for a high-pressure air blower, for example, an air-screw type.

The technical solution proposed by the invention unifies and simplifies the technology for the manufacture and use of the skirt of a hovercraft, expands the functionality of the hovercraft.

Thus, according to the applicant, the proposed technical solution is new, has an inventive step and is industrially applicable, unifying and simplifying the technology of manufacturing and using the skirt of a hovercraft, expanding the functionality of the hovercraft.
