How do you make a vacuum with a hovercraft?
Place it on a smooth floor. Stick the vacuum cleaner hose into the hole and turn it on. The plastic on the bottom should inflate. If it does not, lift the plywood up a bit to let the air get in and inflate the “skirt.” The hovercraft will lift up slightly and start gliding around.
How much does a leaf blower cost?
The average leaf blower costs between $17 and $619, depending on whether it’s gas, electric, or battery-powered. Leaf blowers cost $149 on average. Gas leaf blowers have the highest average at $206, while corded models have the lowest average at $56.
How do you steer a hovercraft?
A downward-pointing fan can only blow air underneath, so hovercraft typically have one or more propeller fans on top of the hull, pointing backward to propel them forward. Usually, there’s a rudder positioned just behind each fan to swivel the air it produces and steer the hovercraft in the appropriate direction.
What kind of air blower does a hovercraft use?
The hovercraft in the video used a gas-powered leaf blower. You could also try an electric leaf blower. Surface – The type of surface that the hovercraft is over will also affect performance. Smooth, flat surfaces allow the formation of an air cushion under the craft.
How does a hovercraft work and how does it work?
The fans direct the air that is under pressure into the chamber beneath the craft. This air cushion lifts the hovercraft up, creating a small gap between the craft and the ground, for air to escape. Check out the short Dragonfly video to see an example of how two students, Rachel and Sara, designed and built a working hovercraft.
Can a hovercraft glide on a cushion of air?
In this science fair project, you will build a working hovercraft that will glide over surfaces on a cushion of air. And it’s simpler to build than you might think! The objective of this science fair project is to build a hovercraft on which you can glide over a flat surface.
How did Rachel and Sara test the hovercraft?
Rachel and Sara found that different types of skirts, one tight and one baggy, affected how the hovercraft worked. To determine how the air was flowing out from beneath the hovercraft, they placed glitter under the hovercraft. Then they tested the two types of skirts for speed and for maneuverability in obstacle courses.
