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.
The following is a list of WIGE or 'wing-in-ground'-effect craft, also referred to as water-skimming wingships or, in Russia, 'ekranoplans'. An A-90 Orlyonok , a Soviet-era ground-effect plane Australia
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 ...
[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 A-90 uses ground effect to fly a few meters above the surface. The Russians classify it as Ekranoplan Class B – it can achieve an altitude of 3,000 m (9,800 ft), placing it between Class A – which is limited to ground effect, and Class C, which exploits the ground effect only during take-offs and landings and otherwise functions as a ...
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.
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 RFB X-114 Aerofoil Craft was an experimental ground-effect vehicle intended to work over water, with the ability to fly out of ground effect when required. It was the last of three such aircraft designed by Alexander Lippisch in the 1960s and early 1970s.
