Abstract

La présente invention concerne un train d'atterrissage (100) et un véhicule aérien sans pilote (600). Le véhicule aérien sans pilote (600) comprend un corps (50), un bras (40) raccordé au corps (50), et le train d'atterrissage (100) monté sur l'extrémité libre du bras (40). Une patte de support (20) est raccordée de manière rotative à un support (10) ; la patte de support (20) comprend une seconde partie d'adaptation (21) ; la patte de support (20) est mise en rotation pour permettre à un train d'atterrissage (100) de commuter entre un état de pliage et un état de dépliage. Lorsque la seconde partie d'adaptation (21) correspond à une première partie de limitation (111), le train d'atterrissage (100) est dans l'état de pliage ; lorsque la seconde partie d'adaptation (21) se met en rotation pour correspondre à une seconde partie de limitation (113), le train d'atterrissage (100) est dans l'état de dépliage. La présente invention occupe un petit espace et est facile à transporter, porter et stocker.
