Ekranoplan A-90 Orlyonok. A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIGE or WIG), ground-effect craft/machine (GEM), wingship, flarecraft, surface effect vehicle or ekranoplan (Russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water.
During takeoff, ground effect can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached. [2] For rotorcraft, ground effect results in less drag on the rotor during hovering close to the ground. At ...
DXF100 - 15 seater wing-in-ground effect craft, designed by China Academy of Science & Technology Development.In 2000, the model is for commercial sale in China. The first buyer of Tianyi-1 used the vehicle to carry tourists around Lake Tai.
[4] [7] It also looked at and discarded a fast oceangoing ship and a sea-based ground effect vehicle. [1] A plan view of a ground effect concept airplane. [8] Many features of this concept were incorporated into the Boeing Pelican ULTRA. Boeing Phantom Works then selected a land-based ground effect vehicle with high drooping wings as its solution.
The ground effect occurs when flying at an altitude of only a few metres above the ocean or ground; drag is greatly reduced by the proximity of the ground preventing the formation of wingtip vortices, thus increasing the efficiency of the wing. This effect does not occur at high altitude. [5] [6] The name Lun comes from the Russian word for the ...
After extensive research, including the development of the small prototype Be-1 wing in ground effect aircraft, the first VVA-14 prototype was completed in 1972. Its first flight was from a conventional runway on 4 September 1972.
The Aerocon Dash 1.6 wingship, a 5,000-ton ground effect vehicle concept. The Aerocon Dash-1.6 wingship was a proposed American ground-effect vehicle intended to carry large cargos and thousands of passengers over long distances at near-aircraft speeds.
DARPA launched the project in mid-2022, wanting a plane that could lift large, heavy loads by skimming the water in ground effect, and capable of operating at mid-altitudes of up to 10,000 feet (3,000 m). Utilizing the ground effect, flying at an altitude equal to 5% of the wingspan can deliver 2.3 times more efficient flight performance.
