5 Amazing Flying Ships | WIG CRAFTS - YOU MUST SEE !

▶ WIG[WING-IN-GROUND] EFFECT WIG effect or “Ground effect“ is the phenomenon of increased lift and reduced aerodynamic drag of a wing flying close to a surface. [ IMO-Guidelines for WIG effect ] Ground effect is an aerodynamic principle that aircraft experience when flying close to the earth’s surface—either over ground or water. The phenomenon takes hold when operating within a distance of one wingspan from the surface. The surface alters the flow field around the wing, resulting in reduced drag and an increase in lift. In simple terms, reduced drag leads to better fuel efficiency and increased lift lets the craft carry heavier payloads. ▶ WIG CRAFT WIG craft is a multimodal craft which, in its main operational mode, flies by using ground effect above water or some other surface, without constant contact with the surface, and is supported in the air mainly by an aerodynamic lift generated on its wing or wings or its hull, or their parts, which are designed to utiliz
