Alekseyev I-21
The Alekseyev I-21 was a Soviet experimental ground-effect vehicle (GEV) developed by the Alekseyev Central Hydrofoil Design Bureau in the 1960s. It was designed to take advantage of the ground effect, a phenomenon where an aircraft or vehicle experiences increased lift and decreased drag when flying close to the ground.
The I-21 was a wing-in-ground-effect aircraft, designed to operate over bodies of water and ice, making it an efficient and unique transportation solution for various regions of the Soviet Union. It had the capability to carry passengers and cargo, and its development contributed to the understanding of GEV technology.
