What vehicle floats on air?
Hovercraft A hovercraft, also known as an air-cushion vehicle or ACV, is an amphibious craft capable of traveling over land, water, mud, ice, and other surfaces.
How does a hovercraft float on a cushion of air?
A hovercraft floats on a cushion of air created by a fan or propeller underneath the craft. This cushion of air reduces friction between the hovercraft and the ground, allowing it to glide smoothly over surfaces such as water, ice, or land. The pressure from the cushion of air supports the weight of the hovercraft, enabling it to "float" above the surface.
What is a hovercraft power source?
A hovercraft is an air cushion vehicle which floats on a cushion of air. Their power source can sometimes be gasoline or sometimes electricity.

What is the principle of floatation of an hovercraft?
It floats on an "air cushion", which really just means that there is excess air pressure below it.
What is the difference between an air boat and a hovercraft?
A hovercraft use a fan to push air underneath the craft and create an air cushion, and on a specially designeg skirt to keep the air cushion contained. The hovercraft will then be suspended with virtually no ground contact by that cushion, pretty much regardless of the speed it's moving at. An air boat at speed might manage to ram some air underneath its hull due to the wide, upturned front, but will settle solidly onto the ground the moment it slows down.
What kind of boat float along on air?
A hovercraft is a type of boat that floats along on a cushion of air. It uses fans to create the air cushion beneath the boat, allowing it to glide over both land and water surfaces.
How does a air cushion help a hovercraft?
An air cushion in a hovercraft helps to lift the craft above the surface using high pressure air. This reduces friction and allows the hovercraft to move smoothly over flat surfaces like water or land. The air cushion also provides stability and control during navigation.
How does hovercraft float?
There are fans in the hovercraft that direct air downwards. The air is 'trapped' by the flexible skirt around the edge of the craft - this creates a cushion of air strong enough to allow the craft to float.
Air is forced under a hovercraft to form an air cushion what is the purpose of this cushion?
A hovercraft is first of all an "aircraft" in that it only uses air to be lifted off the ground by air pressure so that it can move without wheels or any other solid parts such as tracks or gliders like on a sled. Second, the craft needs to be a sufficient height from the ground in order to avoid touching the ground when it moves. The height from the ground depends on how rough and flat the ground is that the hovercraft is to move over. If the "ground" is very smooth and flat, like a plate of glass, then only a very small height is enough. When air is blown under the craft from a blower with enough force this air will escape in a thin sheet (a film) in all directions and lift the craft just enough to float and not touch the surface. . .this film can be called a sort of thin "cushion" as it supports the craft . . like a cushion or pillow supports one's head or the hole body. The air pressure in this film keeps the craft of the ground as long as the air is blown under the craft. . .like happens on a air-cushion-hockey-game-table. If the ground is very rough one needs to lift the craft quite high from the ground. . .say 1 meter for a big hovercraft. . . but this will be practically impossible without creating a hollow space under the craft so that on the edges only a narrow gap is left for the air to escape in a thin layer. This hollow space filled with pressurised air and acts like a pillow. . . a cushion. . . and lifts the craft a sufficient height from the ground so that stones and rough spots are cleared. The edges of the craft must be made of flexible material so that it can move over the rough surface while maintaining a good seal with the ground so that the air "cushion" will not lose its air easily and so the craft retains its height above the ground while moving, due to the air pressure in the "cushion" as long as the air is blown into the cushion. . .a bit like blowing up a balloon with a small hole in it. . .as long as you keep blowing hard enough the pressure will keep the balloon inflated. . .the air cushion under the hovercraft is like a leaky balloon that is continentally being inflated from a strong blower on the hovercraft.
