Abstract

Train d'atterrissage rétractable pour aérodyne, du type dit de fuselage. Il comprend, pour chaque atterrisseur, d'une part, une jambe 5, articulée sur le fuselage de l'aérodyne autour d'un axe de rétraction XX incliné sur le plan longitudinal de symétrie de l'aérodyne, et comportant un manchon 4, dans lequel est monté tourillonnant un equipage mobile 1, 3 portant au moins une roue 2, d'autre part, un vérin 12 de manoeuvre et de contreventement, articule par sa tige 13 sur la jambe 5 et par son corps 16 sur le fuselage, une première bielle 18 étant articulée sur le corps 16 et sur l'extrémité du premier bras 20 d'un levier coudé 19 monté pivotant sur la jambe 5 par l'extrémité de son second bras 21, et dont le coude 24 est relié, au moyen d'une seconde bielle 25, à l'extrémité d'un levier 26 solidaire de l'équipage mobile. Application à la rétraction de trains d'atterrissage d'aérodyne
