A hovercraft works by?
A fan inflates the skirt to the point were the psi trapped by the skirt x the foot print(area) of the hovercraft is equal to the weight of the hover craft and it floats.
What is the hovercraft skirt?
A Hovercraft is the name given to the thick rubber skirt/curtain that sits under the deck of the Hovercraft to contain the air that is used to support (hover) the craft while in motion. This skirt contacts the grounds slightly and as such needs to be replaced after it becomes worn or damaged.

How and why is friction cut down in a hovercraft?
Friction is cut down in a hovercraft by the large volume of air that blows out from under the skirt, making the skirt rise above the ground. In essence, the hovercraft is floating on a bubble of air, and has very little friction with respect to the ground.
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.
What are the main necessary parts of a hovercraft?
Fan system, skirt, platform propulsion systerm
What surface best supports a hovercraft and why?
Water or ice are the best surfaces for hovercraft. They're smooth, not much resistance to the drag of the skirt, and not much blow-off.
Why does the hovercraft need a fan?
hovercrafts run on air. the fan fills the skirt and propels the vehicle forward.
Why are helicopters called helicopters?
Helicopters can hover stationary in the air, but they are not called hovercraft. A hovercraft is a ground based vehicle that rides on a cushion of air that is constantly pumped under a skirt around the base of the vehicle.

Why is it harder for a hovercraft to change direction?
In a perfect scenario, a hovercraft has no contact with the ground, though much of the time, some of the material that makes the skirt will be touching the ground. Even with this minimal contact though, the weight of the hovercraft is counterbalanced by the air pressure its engines generate, rather than the skirt. As air flows freely past itself, and there is little other source of frictional resistance, apart from the hovercraft's engines and air resistance, there isn't much that can stop a hovercraft once it gets going. Incidentally, it means that there isn't much to stop a hovercraft from moving in the first place. Not all hovercraft have the same design, so some roll on corners more than others, so designers try keep the centre of gravity as low as possible, otherwise considerable weight shifting is required to get the hovercraft to turn. Hovercraft accelerate into corners to get into a spin.
What is a hovercraft?
A hovercraft is meant not to fly high but to hover just above the surface of water and land. The propeller is on the bottom of the craft. When the propeller turns, it pushes air down, against the surface. A "skirt" around the edge of the hovercraft helps to confine the air, allowing the hovercraft to ride a short distance above the surface. A second source of thrust moves the craft forward. Instead of using the lift of a wing, the hovercraft rides on a cushion of air.
