GEV is a high speed half-aero plane half-ship that attain level flight near the surface of the Earth, making use of the aerodynamic interaction between the wings and the surface known as ground effect. Best known are the Soviet-made ekranoplanes
Interesting use of CCCP……..
Even features swept wings
Delivering large numbers of combat aircraft rapidly to combat theatres
The Lun-class ekranoplan (NATO reporting name Duck) was a ground effect aircraft designed by Rostislav Evgenievich Alexeev and used by the Soviet and Russian navies from 1987 to sometime in the late 1990s.
It flew using the extra lift generated by the effect of its large wings when close to the surface of the water – about four metres or less. Lun was one of the largest seaplanes ever built, with a length of 73 m (240 ft), rivalling the Hughes H-4 Hercules (“The Spruce Goose”) and many jumbo jets.
The name Lun comes from the Russian for harrier.
Aircraft was powered with eight Kuznetsov NK-87 turbofans, mounted on forward canards, each producing 127.4 kN (28,600 lbf) of thrust. It had a flying boat hull with a large deflecting plate at the bottom to provide a “step” for takeoff.
