Hovercraft in Dictionary
A usually propeller-driven vehicle designed for traveling over land or water on a supportive cushion of slowly moving, low-pressure air. Also called ground-effect machine, hovercraft.
(DOD) A vehicle capable of being operated so that its weight, including its payload, is wholly or significantly supported on a continuously generated cushion or "bubble" of air at higher than ambient pressure. Also called ACV. (Note: NATO uses the term "ground effect machine.")
Air-cushion vehicle (ACV), craft designed to travel close to but above ground or water. It is also called a ground-effect machine or Hovercraft. These vehicles are supported in various ways. Some of them have a specially designed wing that will lift them just off the surface over which they travel when they have reached a sufficient horizontal speed (the ground effect). Others are supported by fans that force air down under the vehicle to create lift. In a plenum chamber vehicle the rate of leakage of this air from underneath the vehicle is reduced by placing a skirt around the lower edge of the craft. In an annular jet vehicle the rate of leakage is reduced by directing the air downward and inward from the outer edges of the vehicle. Air propellers, water propellers, or water jets usually provide forward propulsion.
A hovercraft is a vehicle that is supported on a cushion of air. They are able to traverse many different types of terrain on land and can also travel on water. Many are able to exceed speeds of 95 mph. These are normally called flarecraft. Regular hovercraft are often referred to as Air-Cushion Vehicles.
