General Dynamics WIG design

“WIG” as in “Wing In Ground effect,” or “ekranoplan” configuration. From the same management presentation as the “Big Momma,” here’s the equally minimally described “Advanced Interface Vehicle.” Presumably this means that the interface between the aircraft and the surface of the water is advanced… but how, exactly, it’s any more advanced than any other WIG design is left unclear. It has two high bypass turbofans up front that either are fixed, or can angle downwards, to direct the exhaust below the wing, creating a higher-pressure “cushion” of air between the wing and the waters surface. Other companies had equivalent designs.
