Abstract

L'invention concerne un procédé de manœuvre d'un atterrisseur d'aéronef entre une position déployée et une position rétractée, l'atterrisseur comportant une jambe (2) montée articulée sur une structure de l'aéronef pour être mobile entre les deux positions en étant stabilisée en position déployée au moyen d'un organe de contreventement (10) comportant deux membres (11,12) articulés entre eux dont l'un est attelé à la jambe et l'autre attelé à la structure de l'aéronef, et amenés en position alignée lorsque la jambe est en position déployée. Selon l'invention, on agence sur l'aéronef un actionneur rotatif (20) comportant des première et seconde manivelles (22,24) qui sont montées librement tournantes autour d'un même axe de rotation mais dont la position angulaire relative est commandable et qui sont agencées pour stabiliser les membres de l'organe de contreventement en position sensiblement alignée.The invention relates to a method of maneuvering an aircraft undercarriage between a deployed position and a retracted position, the undercarriage comprising a leg (2) mounted articulated on a structure of the aircraft to be movable between the two positions in being stabilized in the deployed position by means of a bracing member (10) comprising two members (11,12) articulated together, one of which is harnessed to the leg and the other harnessed to the structure of the aircraft, and brought into the aligned position when the leg is in the deployed position. According to the invention, a rotary actuator (20) is arranged on the aircraft comprising first and second cranks (22, 24) which are mounted freely rotating about the same axis of rotation but whose relative angular position is controllable and which are arranged to stabilize the members of the bracing member in a substantially aligned position.
