A giant motor connected to a propeller to push the hovercraft across the ground or water.
How does the flow of air reduce friction of the hovercraft in motion?
their are several forces at work but the main one is a cushion of high perasure air - the fan blades do not so much act as thrust as increasing the air preasure under the hovercraft - a rubber skirt surrounds the craft to keep the air in - if the hovercraft goes to high the air flows out and air preasure is lost and no more hovering - so hovercraft arent really flying so much as just sitting on a cushion of air - forward propulsion can come from a variety of engines but can be also produced by tilting the craft slightly allowing a bit of high preasure to escape from one side of the skirt
i think a good project would be seeing if the speed of the craft is affected by the weight of the person or object on it

The main forces acting on a hovercraft are lift, propulsion, and drag. Lift is generated by the cushion of air under the hovercraft, propulsion is produced by the engines to move the hovercraft forward, and drag is the resistance encountered as the hovercraft moves through the air or water.
the same as any other engine. pistons move up and down spinning a crank. which moves soemthing useful. ie a fan on 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.
There are many hovercraft available for different applications, for example leisure hovercraft, rescue hovercraft, commercial hovercraft - hovercraft come in all sizes, from racing through to leisure and large military hovercraft.
The hovercraft was invented in 2005!
The hovercraft was invented in England
there is no hovercraft in gta4
Hovercraft is a noun.
how did the hovercraft change the world
i like to fly in my hovercraft!
How is friction cut down in a hovercraft? This is done by hovering over the surface Why is friction cut down in a hovercraft? Because the surface of the hovercraft is smooth
the hovercraft was invented by using alot of parts
