Just like a boat, a hovercraft is a marine vehicle. However, it has very distinct features that cannot be observed in other amphibious transportation that we used to know.
Also noted as ACV or air-cushion vehicle, a HOVERCRAFT is an aquatic craft suited for moving over water and land. And more impressively, over the ice, mud, and other surfaces. It is a hybrid boat conducted by a pilot instead of a captain in ships or vessels. Wayback 1959, the world’s first hovercraft made the people in fascination because of its very unique attributes and capability. Its potentiality to easily glide even over the ice and mud make it a perfect vehicle to get around some of the most inaccessible locations in the world. Where in fact, usual marine vehicles like boats cannot sail in and airplanes that can’t land in.
Another extraordinary characteristic of hovercraft is that its dynamics are even more similarly akin to aircraft than boats or land transportations. This is basically the reason why it belongs family or class or air-cushion vehicles. Hovercrafts are known to be an amphibious form of transport because they can transit over both water and land.
Uses of Hovercrafts and more of its remarkable features
Hovercrafts use blowers to create large volumes of air below the hull, which is hardly noticeable above the atmospheric pressure. The difference of the pressure between the higher pressure air down the hull and lower pressure atmosphere above it generates lift. This actually triggers the full to float over the running surface. For its resistance to some degree, the air is usually whirled through holes or slots all over an oval of a disk-shaped platform. This essentially gives the hovercraft the feature of being a rounded-rectangle shape vehicle. Moreover, this cushion is incorporated into a bendable skirt, allowing it to travel over the small interferences without damage.
The first constructive layout of hovercraft was actually determined from a British creation in the 1950s to 1960s. In fact, hovercrafts are now utilized worldwide as functional transportations in numerous applications. More particularly, in disaster relief, military, coastguard, passenger service, sports, and survey purposes. Larger size versions of Hovercrafts have also been invented to carry hundreds of passengers and even vehicles over the English Channel.
The advantages and disadvantages of Hovercrafts
The plus advantage of Hovercrafts is that because of the very low-pressure footprint it can go through in almost any kind of flat surface, it creates no distinctness on how solid or hard the surface is. Whether its water, mud, grass, sand or gravel – all these surfaces are just the same to Hovercrafts. In essence, a hovercraft floats above the surface that it can move up in a river that flows fast. And, at the same speed as it can move down the river.
However, Hovercrafts cannot climb steep hills or move above extremely rugged surfaces. They cannot travel on surfaces that have long sharp objects, which can damage their hull or skirt. Furthermore, the air-based steering structure of a hovercraft makes it quite difficult to maneuver in very limited spaces. Which means areas that are difficult to drive along a confined roadway.
