ground effect

• Phénomène aérodynamique par lequel un véhicule, notamment un avion ou une voiture de course, subit une portance ou un appui accrus et une traînée réduite lorsqu'il se déplace près d'une surface, généralement le sol.

An aerodynamic phenomenon where a vehicle, especially an aircraft or racing car, experiences increased lift or downforce and reduced drag when traveling close to a surface, typically the ground.

1. Aerodynamic phenomenonC1formal

   The increased lift and reduced drag that an aircraft's wings generate when flying close to a surface, such as the ground or water.

   effet de sol

   • The pilot used ground effect to extend the landing distance.
   • Ground effect is most noticeable at altitudes less than half the wingspan.
   • The wing-in-ground-effect vehicle is designed to fly just above the water.
