Personal Hovercraft For Leisure And Fun

There are a lot of ways you can have fun with a personal hovercraft for sale or rent . For starters, you can, for example ... Wait just a New York minute. I'm racing off and may be talking about terms that mean nothing to the reader.Not everyone knows exactly what personal hovercrafts are, so I should go over some basics first. In case you have never heard of this type of vehicle, I ought to explain. Personal hovercrafts are amphibious vehicles that can be used in many different kinds of environments. They are also known as ACVs (air-cushion vehicles). As their name indicates, they move over terrain not by moving on it, but by hovering over it. More precisely, their engine gives them both a cushion to lift them and a thrust to control their movement in either a backward or forward direction.

Although hovercrafts are used for security operations - such as search-and-rescue situations, dive recovery, and military services - one important purpose they're used for is pleasure and entertainment. But more on that later. For now, we should really dive into the nitty-gritty of personal hovercrafts. Because of their manoeuvrability, the personal hovercraft can easily switch from land environments to water environments. Thanks to its cushion of air, the hovercraft only slightly brush the surfaces they're rising above. Usually, they can be driven 9 inches above a given surface.

How Do Personal Hovercrafts Work?

First of all, as weve said, personal hovercrafts are amphibious, which is juts one of the major advantages of this type of transport. This means they are well-suited to a variety of natural landscapes - sand snow, lakes, swamps, frozen rivers, ice and broken ice. This is why they're ideal for security operations; they can access isolated locations quickly and efficiently. Ideas of vehicles that get on by via hovering have been discussed as far back as in the ancient Greek area. However, the history of the modern hovercraft begins with Dr. Christopher Cockerell.

In 1954, this engineer who was working for Marconi when he helped develop radar patented the word hovercraft. Inspired by military scenarios - D-Day and Normandy, to be precise - he wondered how military troops could be brought safely and quickly onto a beach. His first prototype, the Ripple Craft, became, fter much reworking, completely amphibious in 1958. The mechanism worked by using air jets to form a kind of cushion which would both decrease fiction and allow boats to move faster on the water.

The Principle Of Operation Of Air Cushioned Vehicles

Invented in the 1950s, hovercraft (or ACVs) have recently enjoyed a resurgence among people looking for new and innovative ways of spending their leisure time. Until recently, although large versions have been built and used by the military and certain commercial carriers, it hasn't been cost effective or safe enough to built small personal hovercraft. New materials and designs have made this now possible and we see air cushioned craft being used for racing (very exciting), rescue, survey and also leisure activities.

The fascinating thing about these hovercraft of all sizes is that they don't travel on the ground or on water, but hover above it on a cushion of air pressure. A large craft might hover a foot or so off the ground, and a small personal hovercraft just a few inches. If you want to buy a small hovercraft, it's very important to check the safety features before making the sale. All designs use a propeller mounted underneath the vehicle to direct air down to the ground and also out the back to propel it along, called forward thrust.

Downward thrust, or lift, is provided by the air pressure underneath the craft, which has to be contained within a skirt surrounding, and fastened to, the hull. It isn't possible to contain the air completely however - it needs to leak out from under the skirt around the edges to maintain an even air pressure underneath the hull. The skirt is made from very tough material and in the case of larger craft is very substantial indeed.

The hovercraft is pushed forward by re-directing some air, if there is only one engine, to the rear of the ACV. A large version may need two or several powerful engines to carry a big payload of passengers or equipment. Hinged flaps are mounted in the air flow leaving the rear and can be turned so that air flow is re-directed by the pilot's steering mechanism. As you might imagine, a quick and tight turn is just not possible, but it's true that larger boats and ships cannot turn quickly either.

Hovercraft for leisure purposes also have flaps for steering, but also rely on the pilot's body weight. Most versions have handle bar type steering controls. When the pilot turns the handles, he also leans heavily on the side of the craft in the direction he wants to go.. The combination of the two actions can effect quite a rapid turn and racing ACVs can be quite nimble around tight turns, both on land and water.
