METHOD FOR CONTROLLING A LIFT CYLINDER FOR AN AIRCRAFT ENGINE NACELLE, CYLINDER LIFTING SYSTEM IMPLEMENTING THE METHOD AND NACELLE EQUIPPED WITH SAME

A method for controlling a lift cylinder for an aircraft engine nacelle, a cylinder lifting system implementing the method and a nacelle equipped with same. The cylinder lifting system comprises a means (28, 37-39; 64, 68; 50) for modifying the maximum force value of the cylinder activated by a mean...

Zusammenfassung:	A method for controlling a lift cylinder for an aircraft engine nacelle, a cylinder lifting system implementing the method and a nacelle equipped with same. The cylinder lifting system comprises a means (28, 37-39; 64, 68; 50) for modifying the maximum force value of the cylinder activated by a means (37; 46; 74; 92) for determining a portion defined as the start of the extension stroke of the cylinder. As a result of the modification of the maximum force value (28), the pressure source (29) therefore only applies the full force of the cylinder after the starting stroke so as to protect a lock (11) of the reverser cowl (4, 10) forgotten during maintenance. Procédé de contrôle d'un vérin de levage pour nacelle de moteur d'aéronef, système de levage à vérin mettant en œuvre le procédé et nacelle ainsi équipée Le Système de levage à vérin comporte un moyen de modification (28, 37-39; 64, 68; 50) de la valeur d'effort maximal du vérin activé par un moyen (37; 46; 74; 92) pour déterminer une partie déterminée comme le début de la course d'extension du vérin. Grâce à la modification de la valeur d'effort maximale (28) la source de pression (29) applique donc seulement la pleine force du vérin après la course de démarrage de façon à protéger un verrou (11) de capot d'inverseur (4, 10) oublié lors de la maintenance.
