Abstract

L'invention concerne un train d'atterrissage rétractable, selon le brevet principat Le train d'atterrissage comprend, pour chaque atterrisseur, un équipage mobile 1, 3, 4, portant au moins une roue 2, et monte tourillonnant sur un caisson 5 de jambe, sur lequel, s'articulent un amortisseur 8 et un vérin 14 de manoeuvre et de contreventement s'articulant tous deux sur le fuselage. Le caisson 5 est monté pivotant sur un cardan principal 6, lui-même monté pivotant sur le fuselage autour d'un axe incliné. Une bielle 21 est articulée, d'une part, sur un levier 4, et d'autre part, sur le fuselage. Lors de la manoeuvre de l'atterrisseur, le caisson est entraîné en rotation sur lui-même, par le cardan 6 et la bielle 21 commande le basculement de l'équipage mobile Application à l'équipement des aérodynes.
