I did one with some friends and the help of the physics teacher in grade 10. First of all, we made it circular, for stability. I think it was about 4 ft in diameter but it might have been a bit less. We made the skirt out of some strong material I forget what it was called though, lol, a lot of help I am. For the edges of the skirt we wrapped it onto the topside and then stapled it. However there is a trick, because with just staples it will tear through the skirt. So first, duct-tape the skirt to the hovercraft, and (well, we actually duct-taped the entire skirt to make it stronger) then staple it. The duct-tape will prevent the staples from tearing through. Make sure there are holes in the skirt placed specifically in the bottom. They allow for air to escap, but not too big of holes, remember, you can always make them bigger, making them smaller isn't as easy. Duct-tape the edges to these holes as well so they don't tear. We used 2 leaf-blower's for our air source and they were sufficient power to even hover my friend who is...well, he weighs more than the avg person his age.They're definitely more difficult to control in the sense that you have to anticipate what you want to do long before it has to be done. Reactions are much slower than a ground vehicle or airplane, because there's no interaction with the ground or air for manoeuvrability. It's like sliding on ice. The skill required is no greater or less than for most vehicles, but experience is very important since the skills are different.bomba923 said:
The materials needed to build a model hovercraft include a motor, a fan, a battery, a remote control, a lightweight base material such as foam or balsa wood, and a waterproof sealant.
A hovercraft works by using a motor to power a fan that pushes air underneath the craft, creating a cushion of air that lifts the craft off the ground. The air then escapes through small openings around the edges of the craft, creating a downward force that allows the craft to hover.
When designing a model hovercraft, factors such as weight, balance, and air flow are important to consider. The craft should be lightweight enough to be lifted by the cushion of air, but also balanced to prevent it from tipping over. The fan should also be powerful enough to create sufficient air flow to lift the craft.
Yes, a model hovercraft can be controlled remotely with the use of a remote control. The remote control operates the motor, allowing the user to control the speed and direction of the craft.
Yes, there are a few safety precautions that should be taken when operating a model hovercraft. It is important to only operate the craft in open areas away from people or objects. The fan can also be a potential hazard, so it is recommended to wear protective gear, such as goggles, when operating the craft. Additionally, the battery should be handled carefully and not overcharged to avoid any potential fire hazards.
