Abstract :
A hovercraft or air-cushion vehicle (ACV) is a craft, designed to travel over any smooth surface supported by a cushion of slow moving, high-pressure air, ejected downwards against the surface below, and contained within a skirt. Because they are supported by a cushion of air, hovercraft are unique among all forms of ground transportation in their ability to travel equally well over land, ice, and water.
The main parts of a hovercraft are:
Skirt Hull
Lift Fan Thurst Fan
Basic Design:
The lifting motion is controlled by a fan or fans so that an air gap can be formed such separation between the bottom of the hovercraft and the ground provides a motion platform, on which the friction force between the hovercraft and the ground reduces to a very small amount Since a hovercraft does not have wheels, the forward motion is created through the propelling action, which is generated by the use of a propulsion fan
