Quick Summary

A ram-wing craft is a type of vehicle that utilizes the ground effect to achieve lift. This phenomenon occurs when a wing flies very close to a surface, such as water or land, creating a "funnel" effect that increases air pressure and thus lift. Ram-wing craft combine airfoil characteristics with an air-cushion lift system, allowing them to hover when stationary and then gain speed by gradually transferring lift to their wings. While experimental, these craft suggested ways to overcome the speed limitations of traditional air-cushion vehicles.12
