Product Description
Video and lesson investigations on the topic of hovercraft. Key concepts include:
- A hovercraft rises up off the ground.
- Once it is moving, it has no contact with the ground.
- It rides on a cushion of air.
- The air cushion is generated by a large fan and contained by a rubber skirt round the base of the craft.
- They can travel over ground and water in exactly the same way.
- Most hovercraft have separate propellers to move them along.
- They are steered by air rudder.
- They are particularly useful when fast travel over a variety of flat surfaces is needed.
- They can move quickly since they have no contact with the ground.
- This means that it is a good choice of vehicle to use in marshy or other rough areas.
- Hovercraft navigate best when the level of the terrain is fairly consistent.
- They are more difficult to steer and control than a normal land vehicles
