A vehicle that travels above land and water. The word hovercraft is actually a name created in 1955 for an air-cushion vehicle.
HOW DO HOVERCRAFTS WORK?
Hovercrafts work on the two main things lift and thrust.
When working with a hovercraft, the subsistence lift is very important for the vehicle. Lift is an important issue because it is what allows the vehicle to ride on a cushion of air several inches off the ground. This process of lift begins by directing airflow under the craft.
In order to trap the air under the air cushion, a skirt is required. This is done in order to create pressure under the hovercraft which forces the vehicle off the ground. the proper amount of airflow is very important for the protection of the craft's strength.
