An air cushion is a device or structure that utilizes air pressure to provide support, cushioning, or buoyancy. It consists of an enclosed space or chamber filled with air, typically implemented to minimize the impact of forces or create a layer of separation between objects or surfaces.
In the context of transportation, an air cushion refers to a system used in vehicles to reduce friction and enhance maneuverability. Commonly known as an air suspension, it involves the use of compressed air to support the weight of the vehicle instead of traditional springs or hydraulic dampers. This cushion of air helps absorb shocks or vibrations from uneven road surfaces, providing a smoother and more comfortable ride.
Additionally, air cushions find applications in various industries to provide protective cushioning or flotation. In the field of packaging, air cushions are created using special machines that inflate plastic films to form air-filled cushions. These lightweight cushions are then used to protect fragile items during shipping or storage. Moreover, air cushions are utilized in watercraft such as hovercrafts, which rely on a continuous flow of air beneath them to lift the vessel and glide above the water surface.
Overall, an air cushion serves as a versatile mechanism that utilizes air pressure to alleviate impacts, enhance support, or create separation in a range of contexts, from transportation to packaging and water navigation.
The word "air cushion" is a compound word that combines the terms "air" and "cushion".
- "Air" originated from the Old English word "ær" or "ġēr", which can be traced back to the Proto-Germanic word "*awiz". It is believed to have evolved from the Proto-Indo-European root "*h₂eyH-" meaning "breathe". (source: Etymonline)
- "Cushion" entered the English language during the 14th century. It was derived from the Old French word "cousin", which in turn came from the Latin word "coxinus" meaning "cushion for the hip". This Latin term is derived from the Greek word "ky̓ʰoú̯phōn", which refers to a cushion or an upholstery.
