A strut assembly for an aircraft landing gear structure according to the present disclosure is transitioned between an extended configuration, corresponding to the aircraft being off the ground, and a retracted configuration, in which the strut assembly is shortened along its longitudinal axis with respect to the extended configuration, for stowage during flight. The strut assembly includes an upper bulkhead supported by an upper tubular housing, and a lower tubular housing configured to be longitudinally translated with respect to the upper tubular housing. To transition the strut assembly to the retracted configuration, translation of the upper bulkhead with respect to the upper tubular housing mechanically causes translation of the lower tubular housing to a retracted position, such that the overall length of the strut assembly is reduced. In some examples, the strut assembly is an oleo strut assembly.

    Il est décrit un caisson constituant la structure dun train datterrissage daéronef. Le caisson passe dune configuration allongée, laquelle configuration correspond à un aéronef ayant décollé, à une configuration rétractée, dans laquelle le caisson se raccourcit sur son axe longitudinal par rapport à la configuration allongée aux fins de rangement pendant le vol. Le caisson comprend une cloison supérieure supportée par un carter tubulaire supérieur ainsi quun carter tubulaire inférieur configuré pour effectuer une translation longitudinale par rapport au carter tubulaire supérieur. Pour faire passer le caisson à la position rétractée, la translation de la cloison supérieure par rapport au carter tubulaire supérieur entraîne, par voie mécanique, une translation du carter tubulaire inférieur vers une position rétractée, et ce, de manière à réduire la longueur hors tout du caisson. Selon certains exemples, le caisson consiste en un ensemble de jambe à amortisseur oléopneumatique.
