Description

The utility model relates to high cross-country vehicles, in particular, to small vessels and hovercraft.

The subject of the proposed utility model is a compact, maneuverable, economical amphibious hovercraft "Aerogeep".

An analogue of a utility model is the "Amphibious hovercraft" according to patent RU No. 2126753, publ. 1999.02.27, IPC B 60 V 1/18, B 60 V 3/06. The vessel contains an inflatable board, mounted on the rigid sides of the hull around the perimeter. The housing has a flexible air cushion enclosure including side skegs, front and rear flexible elements. The vessel is made with an engine, as well as with propulsion and discharge units with their drive mechanism and control system.

Another analogue is “AIRCRAFT SHIP” according to patent RU No. 2174925, publ. 2001.10.20, IPC B 60 V 3/06, B 60 V 1/04. The vessel has a hull, a pressure unit with a steering device and an air duct for supplying air to the air bag area, as well as a guard with its bow and stern elements and side skegs.

The closest analogue (prototype) to "Aerogeep" is "CAR-ALL-terrain vehicle on the airbag (AUTOMATIC" STRIZH ")" according to patent RU No. 2236963, publ. 2004.09.27, IPC B 60 V 1/00, B 60 V 3/00. The autoplane contains a housing in which there is a cabin with a steering, seats for passengers, a luggage compartment. A lifting fan is installed in the bow of the case. In the middle of the hull is a power plant, and under the bottom

cases - transmission and chassis. The space under the bottom of the housing is divided into a number of compartments, into which air is supplied from the fan through the air ducts through the annular nozzles located around the perimeter of the compartments to form an air cushion. Moreover, in each compartment with the help of appropriate devices can be maintained its own pressure level. To keep the air cushion in the dome space along the contour of each compartment, elastic “skirts” are installed, each of which is made of two parts: the upper one is in the form of a corrugated box, and the lower one is assembled from staggered elastic plates with frequent overlapping.

With all the positive qualities inherent in analogues and the prototype, their significant drawbacks are complex systems for pumping air into the chambers, large dimensions and, as a result, low maneuverability, high cost and difficulty in operation, great complexity of transportation over long distances to the place of operation due to the need to use special equipment. All of them require special equipment to maintain operational characteristics and a special service team for maintenance, which prevents their use for individual purposes.

The goal of the Aerogeep utility model is to create an amphibious vehicle

- with small dimensions (length 2-4 m) and weight (not more than 150 kg), which allows transportation over long distances using a conventional car trailer without the use of special equipment and using it as a universal tool for outdoor activities, tourism, fishing, hunting, inspection, reconnaissance, emergency care, etc .;

- with the possibility of using an engine with a power of up to 40-50 hp, which ensures efficiency (fuel consumption of 5-7 liters per

hour), the noise level is not higher than 85 dB, which allows you to do without headphones and intercoms;

- possessing high maneuverability and controllability in comparison with analogues and prototype;

- high performance, allowing you to do without the use of special tools and maintenance specialists.

This goal is achieved by the fact that the Aerogeep amphibious vehicle consists of a hull assembled from a deck with a cockpit and a bottom made of fiberglass, connected by a contour with a polymer compound, in the cockpit of which an engine with a protection cover is placed, places for the driver and passengers are installed, controls, transmissions for transmitting rotation from the engine to an air propeller located in a protective aerodynamic casing and designed to create translational motion due to jet ui air and creating pressure in the air cushion, ensuring the support of the “Aerogeep” above the movement surface, rudders guiding the air flow of the propeller to the side relative to the longitudinal axis of the “Aerogeep”, the undercasing space to create an air cushion formed by the bottom and elastic segments fixed along the contour from the bottom the bottom, the duct formed by the space between the deck and the bottom and the segments, to divert part of the air flow through the intake opening into the under-hull space, blocks buoyancy made of foam, placed in the space between the deck and the bottom, to ensure the unsinkability of the Aerogeep in an emergency when moving on water.

The achievement of this goal is confirmed by the technical characteristics and test results of the base model:

Length - 3 m 40 cm

Width - 1 m 80 cm

Weight - about 150 kg

Payload - 220 kg

Cruising speed:

- by water - 50 km / h;

- on the ground - 54 km / h;

- on ice and snow - 60 km / h

The steepness of the overcome slope when climbing:

- uphill - up to 20%;

- per wave - up to 0.5 m

Engine 31 HP with electric starter

Fuel tank - 12 l

Fuel consumption (AI92 / 95) - 5-7 l / hour

The device of the utility model is illustrated by the photograph in figure 1 and the drawings presented in figure 2-4.

Utility model "Aerogip" consists of a housing, which is the main load-bearing structural element. The hull consists of an upper deck 1 with a cockpit 2 and a bottom 3. The deck and bottom are made of fiberglass by molding on a matrix and are interconnected by an external polymer compound. In the cockpit 2 there are driver's seats 4 with controls 5 and passengers 6. An engine 7 is installed behind the passenger seat under a protective casing 8.

An air propeller 9 is installed in the rear part of the body in the aerodynamic casing 10. The rotation from the engine 7 to the propeller 9 is transmitted using a belt transmission 11. The transmission is made using know-how and is supposed to be filed with an independent patent application. The air flow from the working propeller is directed backward relative to the movement of the Aerogeep. The upper part of the flow creates traction for translational motion. The direction of movement is ensured by deflecting the air stream to the side relative to the longitudinal axis of the Aerogeep using air rudders 12. The lower part of the stream is designed to create

the pressure of the air cushion in the casing 13. Pressure raises the Aerogeep and thereby minimizes contact friction with the surface along which the movement occurs.

The space of the air cushion is formed between the bottom 3 of the housing and the elastic segments 14 fixed along its contour. The segments 14 (Figure 4) 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 hull 15 is injected into the air duct 16, which is formed by the space between deck 1 and the bottom 3. Then, air through the openings in the bottom 17 and segments 14 enters the housing. Air passing through the segments 14 also creates excessive pressure in them, providing them with sufficient rigidity during movement.

Segments 14 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. Aerogeep does not lose its driving performance in the event of failure of up to 5-7% of segments.

To ensure the buoyancy of the Aerogeep during an emergency during movement on the water surface in the space between deck 1 and bottom 3, foam blocks 18 are glued.

Utility model "Aerogeep" operates as follows.

When starting the engine and turning on the transmission, the propeller is rotated. Part of the air flow from the propeller is directed back along the direction of movement, creating traction for moving the Aerogeep in the horizontal direction. The rotation of the Aeroedip is carried out with the help of steering wheels that direct the pulling force to the side with respect to the longitudinal axis of the Aerodzhip. At the same time as the beginning

horizontal movement, part of the air through the intake hole in the lower part of the flow is directed into the duct formed by the inside space and the elastic segments. This flow creates overpressure in the casing space. The pressure lifts the “Aerogeep” above the surface, which minimizes the friction and resistance to translational motion. The same stream, passing through the elastic segments, creates excessive pressure in them, providing them with a certain rigidity necessary to maintain the pressure of the air cushion. At the same time, Aerodzhip acquires the possibility of horizontal movement in the desired direction with minimal contact with the surface of water, soil or snow.
