Hõljumasin

Hõljumasin is an Estonian term that translates to "hovercraft" or "air-cushion vehicle" in English. It refers to a type of craft that is propelled over a surface by a cushion of air. This air cushion is generated by fans that force air downwards, creating a pressurized layer between the vehicle and the ground or water. This reduces friction, allowing the hõljumasin to move with relative ease over various terrains, including land, water, ice, and mud.

The principle behind a hõljumasin is similar to that of a hovercraft. A skirt or flexible containment system around the base of the vehicle helps to trap the air, maintaining the cushion. Propulsion is typically achieved by separate fans or propellers that push the vehicle forward. Hõljumasinid can vary in size and purpose, from small personal transport craft to larger military or cargo vessels. Their ability to traverse diverse surfaces makes them suitable for amphibious operations, rescue missions in difficult environments, and recreational use. The technology has been developed and utilized in various countries, with Estonia having its own contributions and applications of this type of vehicle.
