Abstract

L'invention concerne un train d'atterrissage rétractable pour aérodyne, du type dit de fuselage. Le train d'atterrissage comprend, pour chaque atterrisseur, un équipage mobile 1, 3, 28, 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 15 de manoeuvre et de contreventement s'articulant tous deux également sur le fuselage. Le caisson 5 est monté pivotant autour d'un axe longitudinal sur un cardan principal 6 lui-même monté pivotant sur le fuselage autour d'un axe XX incliné et ne passant pas par l'articulation de l'amortisseur 8 sur le fuselage Lors de la manoeuvre de l'atterrisseur, l'amortisseur 8 joue rôle de barre directrice orientant l'axe du caisson qui est entraîné en rotation sur lui-même, par le cardan 6 pivotant autour de l'axe XX. Application à l'équipement des aérodynes.
