Plywood hovercraft

Plywood hovercraft  Plywood hovercraft I propose to consider the topic, a boat on an air cushion. The topic is not new, but very interesting among tourists, and especially among fishermen. Products are capable of moving on land and immediately move to the water surface. In winter, over snow, ice and thawed patches. How is this possible? Let's look at this on a prototype.
This will require lumber, plywood, polyethylene, scissors, and three petrol blowers to clean the foliage.

For more did not work, consider an air cushion boat. He is able to walk on water not only with the skirt of the air bell, but also without it, like a speedboat.
Some craftsmen make their projects from plywood.
Assemble the bottom of the boat from pieces of plywood, cut out and set stiffness triangles along the edge of the plywood.

 Plywood hovercraft The screw is driven by belts using a tension through the bearings. The upper pulley is made of plywood. The body is prepared for fiberglass coating.

This manufacturing option is slightly easier to manufacture. A form is built from the same plywood and then pieces of foam are laid out on it, glued together with polyurethane foam.
Plywood hovercraft Then the passenger compartment and the main air duct are turned over. The foam has properties to expand upon hardening, so 100 nails are used as dowels for fixing.

There are two main ways of filling a skirt with air. One, it's like at the beginning of the article, a free-standing fan. The motor drives the air with its blades and the ship is lifted off the ground. But there is no movement. An additional motor with a propeller is installed for movement.
Another is when a part of the air pressure is taken from the main stream, by means of the installed jumper, and is directed to raise the object. The difference between the two methods is that in the second one the vessel immediately starts moving when it rises.

Plywood hovercraft Then they install the engine, blades, steering wheel, seat, protection and, of course, it is covered with paint

It is a consumable, like tires that wear out and break through, or like shoes that constantly break. For its manufacture, rubberized or PVC-coated reinforced fabric is suitable. It should be well sewn and glued, The skirt is removable, it is a kind of tape, which is fixed on the top with clips, and at the bottom on the garters through which air escapes, or when firmly attached from below has round holes for air outlet.

 Plywood hovercraft Plywood hovercraft Engines are used, depending on the dimension, from ten horses. If the horsepower exceeds fifteen horses, the boat must be registered.
