Abstract

La présente invention concerne un support de pied d'amortissement pour un petit véhicule aérien sans pilote comprenant une base de montage (1) et deux tiges de support (2) qui sont disposées en parallèle; des tiges de raccordement en arc (3) sont disposées verticalement et de manière fixe sur les tiges de support (2); un manchon (4) gainé sur les extrémités des deux tiges de raccordement (3); les extrémités des deux tiges de raccordement (3) sont raccordées au moyen d'un ressort (30); une surface des tiges de raccordement (3) est pourvue d'une bague de retenue (31); une paroi interne du manchon (4) est pourvue d'une pluralité de nervures élastiques (40) correspondant à la bague de retenue (31); une surface inférieure de la base de montage (1) est pourvue d'une cavité (10) correspondant à un contour du manchon (4) et une plaque de recouvrement. Lorsque le véhicule aérien sans pilote atterrit, les tiges de support (2) entrent en contact avec le sol, la vibration générée est transmise au moyen des tiges de raccordement en arc (3), et la vibration est amortie au moyen du ressort (30) et des nervures élastiques (40), réduisant ainsi largement l'effet de vibration pendant l'atterrissage et empêchant le véhicule de se retourner. La structure globale de l'invention est simple, et son coût est faible.
