Hovercrafts or cushion floats are a type of water-land vehicle that is placed on a cushion of air using compressed air and can move on different surfaces such as water, mud, sand and even solid and rocky surfaces. These vehicles were initially developed for military applications, but with the passage of time and the advancement of technology, they also found commercial, rescue and recreational applications. There are different types of hovercraft, each of which is classified based on the design, dimensions, application and different systems they have. In the following, we will introduce and review the types of hovercraft and their applications. 1. Military hovercrafts are one of the first and most widely used types of hovercrafts, military hovercrafts. These hovercrafts play a special role in military operations due to their speed and ability to move on various surfaces. They are used for the rapid transport of troops, equipment and heavy vehicles, and they can also move on the beach and enter the water, which is very effective in amphibious operations. The most famous military hovercrafts are the LCAC (Landing Craft Air Cushion) models used by the US Navy. These hovercrafts can carry tanks, trucks and heavy equipment. 2. Commercial hovercrafts Commercial hovercrafts are mostly used to transport cargo and passengers in remote or inaccessible areas. In countries with limited access to transportation infrastructure, commercial hovercrafts can be used to connect islands, coastal areas, and even swampy areas. These types of hovercrafts are usually large in size and their design is optimized for the safe transportation of cargo and passengers. Among the most famous companies that produce commercial hovercrafts, English companies such as Griffon Hoverwork can be mentioned. 3. Rescue hovercrafts Rescue hovercrafts are designed for rescue operations in difficult and inaccessible areas. These hovercrafts are very effective in rescue operations due to their ability to move on various surfaces. When floods, storms or other natural disasters cut off access to residential areas, rescue hovercrafts can easily penetrate these areas and provide the necessary assistance. They are usually equipped with medical systems and rescue equipment such as stretchers and medical equipment. 4. Recreational Hovercrafts Recreational hovercrafts are usually designed in smaller sizes and are used for personal and recreational use. These types of hovercrafts are often used in sports competitions and public shows and are cheaper and smaller in terms of price and size than other types. Recreational hovercrafts, due to being light and portable, can provide users with a special and different experience of movement on water and land. 5. Environmental and Scientific Hovercrafts Hovercrafts are also used in scientific research and environmental studies. These vehicles are very suitable for accessing swampy areas, wetlands and nature reserves that other vehicles may not have access to. Researchers use hovercrafts to survey ecosystems, take water, soil, and other environmental studies. The special features of hovercrafts allow researchers to access sensitive areas without harming the environment. Design and structure of hovercrafts. Hovercrafts usually consist of a central structure that includes a control room, engine, and air production and control systems. Compressed air is directed under the hovercraft by special engines and lifts the device off the ground by creating an air cushion. This cushion of air, also known as an air domain, allows the hovercraft to move without direct friction with the surface of the ground or water. To control the direction of movement, vanes or side motors are usually used. Disadvantages of using a hovercraft, although hovercrafts have many advantages, some of them also have disadvantages: • High energy consumption: hovercrafts need a lot of energy to create compressed air and maintain the air cushion. • Difficult to control: Hovercrafts are difficult to control in strong wind or high waves. • High cost: Hovercrafts are expensive to build and maintain, and this can limit their use.
