The jack-type lifting system includes a valve for modifying a maximum force value of a lifting jack activated by a protrusion for determining a determined portion such as the beginning of the extension stroke of the lifting jack. Thanks to the modification of the maximum force value, a pressure source thus applies the full force of the lifting jack after a start-up stroke so as to protect a lock of a reverser cowl which has been forgotten during maintenance.

Method for controlling a lifting jack for an aircraft engine nacelle, a jack-type lifting system implementing the method and the thus equipped nacelle

The invention relates to a method for making a nacelle element () that includes the steps of: (A) forming an array of heating resistors on a substrate using a photolithographic method; (B) applying a web () of composite materials onto the array obtained in step (A); (C) applying an inner skin () onto the de-icing assembly () thus obtained. The invention also relates to a nacelle including such an element ().

Method for making a nacelle de-icing element

The invention relates to a method for making a deicing system on a panel () of a nacelle comprising an outer skin () having at least one hole and an inner skin (), characterized in that it comprises the following steps: A. a grid of resistive elements is positioned on the outer skin () with respect to the hole(s) by a positioning means; B. the grid of resistive elements is applied by an application means to the location determined in step A to form the deicing system; C. a surface coating is applied to the resulting deicing system. The present invention also relates to an air inlet lip and to a nacelle comprising a deicing system produced by such method.
