In aircraft, the ground effect is the reduced aerodynamic drag that an aircraft's wings generate when they are close to a surface.
Ground-effect vehicle
…GEM), wingship, flarecraft, or surface effect vehicle, is a hybrid surface vehicle/aircraft that makes use of wings to generate minimal lift and ground effect, to reduce aerodynamic drag. Ground effect is the interaction between a moving wing and a stationary surface below it. Typically, a GEV will glide just…
