i don't know, probably j.g
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.
A hovercraft can move on water by forcing air downward. The hovercraft will be lifted by the air. The craft can move by rotating the Jets of air in the direction you want to go.

A motor can seperately power a fan that blows either in a forward movement or reverse movement. The air can be projected towards a direction with blades/rudders. The combination of both a fan blowing towards the ground (creating lift), and an upright fan blowing to create movement can make a hovercraft "go"
Sir Christopher Cockerell is usually credited for inventing the hovercraft.
hovercrafts run on air. the fan fills the skirt and propels the vehicle forward.
The blade pitch , or angle , is tilted forward through the rotor head .
howercraft can move on rough surface
A hovercraft.
The air cushion beneath the hovercraft reduces friction with the water, allowing the vehicle to move quickly on the surface. This cushion of air creates lift and buoyancy, enabling the hovercraft to glide over the water with minimal resistance.
Sure, if it's designed right. See the "air-boats" used in Florida everglades, the Hovercraft, and propeller aircraft.
the same as any other engine. pistons move up and down spinning a crank. which moves soemthing useful. ie a fan on a hovercraft.
