Patent number: 12233518Abstract: A method for the installation of a threaded fastener (10) in a structure, the threaded fastener comprising a screw (20) and a nut (28), the method comprising the following steps: a) inserting the screw into the structure, and tightening the nut onto the screw, b) simultaneously transmitting/receiving ultrasonic waves into/from the fastener for the measurement of a parameter representative of a variation in said waves, said first parameter providing an indirect measurement of an axial tension in the screw, c) stopping the screwing when a target value for the first parameter is reached. The process further comprises determining the thickness of the structure to be tightened, and determining the target value of the first parameter in accordance with the thickness of the structure to be tightened and the geometrical characteristics of the fastener (10).Type: GrantFiled: May 2, 2024Date of Patent: February 25, 2025Assignee: LISI AEROSPACEInventors: Benoit Regnard, Clément Rousseau

Patent number: 11826816Abstract: This relates to a method for the quality control of a blind fastener installation in a structure comprising a sleeve and a core bolt, with a deformation of a rear side of the structure, a signal being generated during the installation process. The process includes a) identification of two notable points of the signal, chosen among: pulling start point (S1); buckling (B1) of the sleeve; contact (B2, S2) of the sleeve or of the core bolt; force setpoint (B3) or fracture (S3) of a portion of the core bolt; b) estimation of a first parameter as a function of a notable point, characterizing a bulb in contact with the rear side; c) estimation of a second parameter as a function of a notable point, characterizing a tension applied in the core bolt; and d) for each estimated parameter, comparison with a condition that indicates the proper installation of the fastener.Type: GrantFiled: March 7, 2022Date of Patent: November 28, 2023Assignee: LISI AEROSPACEInventors: Dimitri Billaud, Benoit Regnard

Patent number: 10851825Abstract: The invention concerns a metal attachment for providing an electrically conductive surface through the entire thickness of structural elements to be assembled. The attachment thereby comprises a head (12) and a smooth shank (14) extending along an axis of revolution, characterized in that the shank comprising at least one conductive portion (24) and one lubricating portion (22) disposed along the axis of revolution of the attachment along at least one length of the shank. The attachment according to the invention provides a conductive surface through the entire thickness of the structure in which it is installed. The attachment according to the invention is intended, in particular, for aeronautical applications.Type: GrantFiled: July 21, 2014Date of Patent: December 1, 2020Assignee: LISI AEROSPACEInventors: Benoit Regnard, Julien Goyer, Martial Broucke

Patent number: 9574603Abstract: The present invention pertains to a washer (11) for a female fastener (12, 12A), particularly a nut or collar, said washer comprising an annular base (15) and a substantially cylindrical skirt (13) of an outer periphery of the annular base, said annular base comprising a central orifice (18) coaxial with the axis (14) of the skirt, characterized in that the annular base is at least partially covered with a layer (21) of a viscous composition capable of forming a liquid-tight coating through polymerization. When installing a nut having such a washer onto a male fastener such as a pin (33), the spreading of the viscous layer makes it possible to fill in the gaps (36) of the assembly, the polymerization of the composition ensuring its leak-tightness afterwards.Type: GrantFiled: November 6, 2013Date of Patent: February 21, 2017Assignee: LISI AEROSPACEInventors: Florent Verdier, Benoit Regnard
