Abstract

L'invention concerne un aéronef comportant un train d'atterrissage dit actif, ledit train comprenant : a. une jambe (131), dite pilier, en liaison pivot avec la structure de l'aéronef ; b. une jambe (132), dite de support, en liaison pivot avec la jambe (131) pilier selon un axe (135) parallèle à l'axe de tangage de l'aéronef et portant un moyen (140) de liaison au sol de l'aéronef ; c. un vérin (150) apte à déplacer la jambe (132) de support relativement à la jambe (131) pilier selon une rotation autour du pivot (135) de liaison entre les deux jambes ; d. des moyens (160) pour déplacer la jambe (131) pilier par rapport à la structure de l'aéronef autour de l'axe (125) de liaison pivot de cette jambe avec ladite structure.The invention relates to an aircraft comprising a so-called active landing gear, said landing gear comprising: a. a leg (131), called a pillar, in pivot connection with the structure of the aircraft; b. a so-called support leg (132) in a pivot connection with the pillar leg (131) along an axis (135) parallel to the pitch axis of the aircraft and carrying a means (140) for connecting the ground to the aircraft; vs. a jack (150) capable of moving the support leg (132) relative to the pillar leg (131) according to a rotation about the pivot (135) connecting the two legs; d. means (160) for moving the pillar leg (131) relative to the structure of the aircraft around the pivot link axis (125) of this leg with said structure.
