If ground effect are so much more efficient why aren’t we using them for flights, from Europe to the US for example?
In: Engineering
The ground effect increases lift. At the same time flying at sea level mean the air pressure is a lot higher and it increases drag. The result is it is more fuel-efficient to fly very high up.
Flying where you have a ground effect would be a lot less safe. Airplanes can crash into ships, large waves, islands, and other airplanes because there is no vertical separation.
