ground effect vehicles (GEVs) that were something of a hybrid between a ship and a large airplane. Their stubby wings didn’t provide enough lift for the vehicle to fly in the traditional sense ...

Over the past few years he’s worked on a series of ground effect vehicles which exploits the increased lift and reduced drag when flying close to a surface. Unlike full-sized counterparts ...

"These vessels remain airborne without continuous contact with the surface, supported by the aerodynamic lift generated by their wings, hull, or components designed to exploit ground effect." ...

The twisting caused one end of the wing to have more lift and the other end to have less lift. To produce the same effect ... orientation relative to level ground. The Wrights placed the elevator ...
