Abstract
A hovercraft supporting underpart of the hull has a number of interconnected layers to provide an increased surface area. The flow of air follows arrows 1, 2 and 3 to strike upon the different surfaces introduced by the layers. Hence, it is said that for the same force, the increased surface area provides a smaller force per unit area, i.e. a smaller pressure. This is said to allow previously large hulled hovercrafts to have smaller hulls. <IMAGE>
Description
LAYERED HOVERCRAFT HULL
This invention relates to a layered supporting underpart of the hull of a hovercraft.
Hovercrafts are well known amphibious vehicles that operate on the principle that its weight is supported by a pressure buildup of air created between the ground's surface and the vehicle enclosed by a skirt underneath the hull of the vehicle. Hovercrafts are, however, large in size to provide a large surface area. This is such that for the same force, the larger the surface area the less force exerted per unit area. Hence less pressure is needed inside the skirt enclosed air cushion to lift the hull up.
According to the present invention there is provided a layered hull interconnected at the entre of each layer by means of a tube with fillets attached to the layers at either end of the tube. The number of layers depend on the surface area needed. The principle of layers can be adapted for use according to the shape of the hull. For the purpose of this patent, a rectangular hull will be used.
With reference to the accompanying drawing a specific embodiment of the invention will be described:
Figure 1 shows in perspective, the interconnected layers of the hull.
Figure 2 shows in perspective, the interconnecting tube between the layers.
Figure 3 shows the supporting underpart of the hull integrated with the rest of the hull along with the direction of air flow.
Referring to the drawing the flow of air follows that indicated by the arrows 1. Upon entering the area beneath the hull enclosed by the skirt they proceed to follow the path indicated by the arrows 2. This fills up the different layers, thus providing more surface contact area for the force of the flowing air to act upon. The outside surfaces of the layers also provide surfaces of contact' as can be seen by the air flow pattern 3.
Claims (2)
1 An interconnected layered hovercraft supporting underpart of the hull wherein interconnected layers are provided for increased surface area.
2 An interconnected layered hovercraft supporting underpart of the hull as claimed in Claim 1, which can be adapted to suit any shape hull.
