![]() Who invented the hovercraft? The scientific principles behind the vehicles were first demonstrated by Sir Christopher Cockerell in 1955. ![]() They can also be used in place of boats to move large groups of people across bodies of water. They can transport people and equipment over rough terrain. Because of their amphibious nature, they’re popular with militaries. Today, hovercrafts are used in many parts of the world for a variety of reasons. This is then split between thrust and cushion as needed. Other hovercrafts have one larger engine that produces a single air stream. One is for thrust (forward motion), and the other creates the pressurized air cushion. Some hovercrafts use two separate engines. How do they move? The engines also produce an air current that pushes them forward. Of course, that’s just how these crafts hover. These help to stop the pressurized air from escaping. To help hovercraft engines work most efficiently, hovercrafts have skirts made of fabric surrounding their bases. It depends on the size of the hovercraft and the power of its engines. How high above the ground can these vehicles hover? This can range from six inches to over seven feet. These fans blow air underneath the hovercraft to lift it off of the ground. How does a hovercraft work? They have engines that power fans. Although it might sound like magic, it’s actually pure science! They hover on a cushion of pressurized air. ![]() Hovercrafts are more like airplanes than either boats or cars. ![]() ![]() That means they can travel over both land and water. Hovercrafts are known as amphibious vehicles. They are also sometimes called air- cushion vehicles or ACVs. It’s true! We call these special vehicles hovercrafts. But did you know that there are real vehicles that can hover and travel over both water and land? Do you like science fiction movies? If so, you’ve probably seen plenty of interesting space ships that hover and float about like magic. ![]()
