"Andrei F." . Andrey is from the city of Noyabrsk of the Yamalo-Nenets Autonomous Okrug and this is not the first car making him.
On test videos.
The ship was built according to the American project "Sevtek", but redone for our materials.
The engine from the VAZ-21083 with a power of 74 hp was used. SVP refers to gims, since the internal combustion engine is up to 75 hp registered as homemade according to pr. No. 500-501 gims.
The body is made of a type of sandwich made of expanded polystyrene extruded with a size of 20 X 600 X 1200 mm. Used three packs of 20 pieces each!
Dimensions (without rudders, pure body) 5 X 2.5 m!
The weight of the whole structure is 360-370kg (with ICE, roof, frame and other components). The cabin is heated from the internal combustion engine and an additional stove from the Gazelle.

The pushing screw 1700 mm three-blade, with varying angles of the blades.
Forcing fans of the company "Multiving" with a diameter of 500 mm, 10-blade two pieces.
Assembly is on a flat floor. Expanded polystyrene sandwiches for insulation are glued with mounting foam for outdoor use.
They are glued on top with fiberglass in a single layer using epoxy. From the resulting panels are cut to the desired size of the panel.
After the pattern, the panels are assembled into the hull of the boat, according to the drawings.
From the inside, the panels are glued with an additional layer of fiberglass, since then it will be very difficult to crawl to these surfaces.
Assembly of the body continues.
Builder car makes everything do it yourself.
The boat takes a recognizable shape.
In total, eight layers of fiberglass will be glued, not counting the overlap in the joints. 4 layers are applied outside and 4 layers inside. After drying, you can safely walk. No more than two layers of fiberglass can be applied at a time. Carefully smooth it so that there are no air bubbles and delamination. After drying, you can paste over Shumkov and dermantine. Boat on the street.
Fiberglass Biax + -45gr holds the load in two directions.
Triax holds the load in three directions.
Quadroax holds the load in four directions. The glass fabric should not be impregnated with paraffin, so that later it does not have to evaporate the paraffin, which leads to a loss of fiberglass properties. Fiberglass should be structural.
The production of the frame for the engine, under the frame, under the cab begins.

In construction, ETAL-153 resin was used, now it is no longer on sale, together with it is ED-16 resin. The hardener used ETAL-45m-hardens at low temperatures up to +2 degrees. Fiberglass EZ / 1-200.

For the trip, two boost fans are used, which inflate the skirt under the bottom of the boat and lift it from the surface of the earth, water, sand, ice.
The surface should be more or less even, if there is a hummock or hummocks high from ice, then SVP will not be able to overcome.
The movement is due to the repulsive screw, gave gas and drove off, threw gas and stopped.
For driving, it is necessary to pressurize 7 meters of cubic air per second under the bottom (maximum 11.5 m3 / s) and a pressure of 550 Ra from each fan.
For the skirt, French tent fabric 600 g / m2 was used.

The peculiar management of SVP requires habit and skill. The carrying capacity of the SVP is less than that of motor boats by a factor of 1.5–2 and is more critical of the weight distribution at a self-made car.
However, the speed of movement of an hovercraft is much higher than motor boats and cars of the same power, as well as higher passability and amphibiousness in water, sand, swamp, ice, snow. It goes perfectly in the snow, falls 5-7 cm, but after stopping there are difficulties starting off.

Good luck to Andrey Dmitrievich Fandyushin in the construction of SVP!
