Description

The utility model relates to air-cushion vehicles, namely to air-cushion vehicles comprising a body including a deck with seats for a driver and passengers and a bottom, an engine connected to a propeller by means of a transmission, elastic segments are arranged around the bottom of the bottom, restricting the casing space to create an air cushion, an air duct with the possibility of diverting part of the air flow through the intake opening into the casing space to create an air cushion pillows, controls and can be used to transport passengers and goods by land, off-road, on snow cover and on water barriers.

A vehicle is known as an air cushion, comprising a hull including a deck with seats for the driver and passengers and a bottom, an engine connected to the propeller by means of a transmission, elastic segments are located around the bottom perimeter, limiting the hull space for creating an air cushion, an air duct with the possibility the removal of part of the air flow through the intake opening into the housing to create an air cushion, controls (see application for a patent of the Russian Federation for utility model No. 2010 118578, published 2011) In it, the casing is made of high-strength composite materials, divided into compartments.

The disadvantage of this solution is the low reliability associated with the fact that composite materials are susceptible to damage. When hitting a solid obstacle while driving, such a housing may be damaged. As a result, such a hovercraft has a short life.

An air cushion vehicle is also known, comprising a hull including a deck with seats for the driver and passengers and a bottom, an engine connected to the propeller by means of a transmission, elastic segments are located around the bottom of the bottom, limiting the casing space for creating an air cushion, an air duct with the ability to divert part of the air flow through the intake opening into the housing to create an air cushion, controls. (See RF patent for utility model No. 63759, published 2007). The hull consists of a deck with a cockpit and a bottom made of fiberglass, connected by a polymer compound to the contour.

This device is taken as a prototype of the proposed utility model.

The disadvantage of this prototype is the low reliability associated with the fact that the frame is made of fiberglass, that is, from a material that is easily susceptible to damage. In the event of a collision with obstacles, such material may crack, break. As a result, such a hovercraft has a short life.

Based on this original observation, the present utility model is mainly intended to offer an air-cushion vehicle that allows at least to alleviate the above drawback. Namely, the technical problem being solved by the proposed utility model is to increase reliability and increase the service life of the hovercraft.

To achieve this goal, the hull, in the form of a deck and a bottom, is made of rigid panels of aluminum alloys interconnected.

Due to this, it becomes possible to provide increased reliability and increased service life of the hovercraft. Unlike fiberglass, rigid panels made of aluminum alloy have significant reliability, are resistant to damage, and provide the entire vehicle with an air cushion longer service life. When encountering obstacles, rigid aluminum alloy panels do not break, but only become deformed.

There is a variant of the utility model in which rigid panels of aluminum alloys additionally have stiffeners.

Thanks to this characteristic, it becomes possible to further increase the strength of the vehicle body on an air cushion.

There is also a variant of the utility model in which rigid panels of aluminum alloys are additionally connected to the frame.

Thanks to this characteristic, it becomes possible to easily mount rigid panels in the manufacture of a vehicle on an air cushion, while increasing the strength of the body, and as a result leads to increased reliability and longer service life of the vehicle on an air cushion.

There is a variant of the utility model in which rigid panels of aluminum alloys are interconnected hermetically by welding.

Due to this characteristic, it becomes possible to ensure the watertight connection of rigid panels, and as a result to ensure the buoyancy of the vehicle on an air cushion on water in an emergency during movement on a water surface.

The claimed vehicle hovercraft has a set of essential features unknown from the prior art for devices of similar purpose, which allows us to conclude that the criterion of "novelty" for the utility model.

Other distinguishing features and advantages of utility model 90 clearly follow from the description below for illustration and not being restrictive, with reference to the accompanying drawings, in which:

- figure 1 schematically depicts a General view of the vehicle on an air cushion according to the proposed utility model, side view;

- figure 2 schematically depicts a General view of the vehicle on an air cushion according to the proposed utility model, front view;

- figure 3 schematically depicts a General view of the vehicle on an air cushion according to the proposed utility model, top view;

An air cushion vehicle contains a housing including a deck 1 with seats 2 for the driver and passengers and a bottom 3. The engine 4 is connected to the propeller 5 using a belt transmission 6. The engine can be installed with power up to 40-50 hp

The propeller 5 is located in the protective aerodynamic casing 7. The air flow from the working propeller is directed backward relative to the movement of the vehicle on an air cushion. It is divided into two streams: upper and lower. The upper part of the flow creates traction for translational motion. The direction of movement is ensured by deflecting the air stream laterally relative to the longitudinal axis of the vehicle on the air cushion using the air control wheels 8. Air control wheels 8 are connected to the lever 9 for controlling the air wheels, which is located on the deck, near the driver's seat 2. The lower part of the stream is designed to create air cushion pressure in the housing 10. Pressure raises the vehicle in an air cushion and thereby minimizes contact t rhenium with the surface on which the movement occurs.

The space of the air cushion is enclosed between the bottom 3 of the body and the elastic segments 11 fixed along its contour. The segments 11 are made of durable airtight, water-repellent, frost-resistant fabric. To create air cushion pressure, the lower part of the flow through the intake hole in the rear of the housing is pumped into the housing 10. Segments 11 are the main element subject to wear due to friction on the surface of movement. All segments are identical, which ensures their interchangeability and high maintainability of the product.

A utility model of an air cushion vehicle operates as follows.

When starting the engine 4 and turning on the transmission 6, the propeller 5 is driven into rotation. A part of the air flow from the propeller is directed back along the direction of movement, creating traction for moving the vehicle in the air cushion in the horizontal direction. The rotation of the vehicle on the air cushion is carried out using the steering wheels 8, directing the pulling force to the side with respect to the longitudinal axis of the vehicle on the air cushion. Simultaneously with the beginning of horizontal movement, part of the air through the intake opening in the lower part of the flow is directed to the housing 10. This (lower) flow creates excess air cushion pressure in the housing 10. The pressure lifts the vehicle on the air cushion above the surface, which minimizes friction and resistance to translational motion. The same stream, passing through the elastic segments 11, creates excessive pressure in them, providing them with a certain rigidity necessary to maintain the pressure of the air cushion. In this case, the hovercraft acquires the possibility of horizontal movement in the desired direction with minimal contact with the surface of the water, soil or snow cover.

The preceding description of exemplary embodiments of the utility model provides an illustration and description, but is not intended to be exhaustive or to limit the utility model to the exact forms, variants, and sizes described. Modifications and changes are possible in the light of the above description or can be obtained from the application of the utility model.

The utility model can be manufactured at the enterprises of the automotive, aviation and shipbuilding industries, as well as at enterprises producing products from aluminum alloys, which meets the criterion of "industrial applicability" for utility models.

In accordance with the proposed utility model, a prototype of an air cushion vehicle manufactured by Plazmek OJSC was manufactured with the following technical parameters: length - 3 m 90 cm, width - 1 m 70 cm, weight - 80 kg.

As an aluminum alloy, an aluminum alloy AMg having an increased corrosion resistance was used. The AMg alloy is stronger than pure aluminum and less susceptible to the negative effects of precipitation and other atmospheric influences. Pontoon modules are plasma welded from a sheet with a thickness of 2 mm.

A 45 hp engine was installed. with electric starter, fuel tank - 20 l.
