Publication number: 20230045934Abstract: An actuator includes a body and at least a first offset connection port that is connected to the body by a first duct projecting from the body. The first connection port is mechanically connected to the body at least by first and second struts. The first strut and the second strut extend from the first connection port, respectively, to a first segment of the body and to a second segment of the body that is axially spaced apart from the first segment. An undercarriage includes such an actuator as its locking or unlocking actuator.Type: ApplicationFiled: January 20, 2021Publication date: February 16, 2023Applicant: SAFRAN LANDING SYSTEMSInventors: Yves COURTOIS DE LOURMEL, Sébastien MESSE, Jean-Baptiste KAMIS, Arnaud LE BRETON, Nicolas NGUYEN

Patent number: 11370176Abstract: A method of additive manufacturing including defining contiguous portions over a ceiling of a cavity of a part, including a central portion defined entirely by first edges, and peripheral portions defined by second edges and by a portion of a frontier of the ceiling. Defining a capital by facets that bear against the first edges and that converge towards an apex, and defining a slender support that extends from the capital to a cavity floor while being centered on the apex. For each peripheral portion, defining a capital by facets that bear against the second edges and that converge towards a terminal edge extending in a plane that is normal to a wall of the cavity, and defining a rib support that extends in the normal plane between the terminal edge and a wall of the cavity. Manufacturing the part including the cavity while making the supports and capitals.Type: GrantFiled: June 14, 2019Date of Patent: June 28, 2022Assignee: SAFRAN LANDING SYSTEMSInventors: Yves Courtois De Lourmel, Sébastien Messe, Gérard Balducci, Thierry Caule

Publication number: 20210252794Abstract: A ceiling of a cavity is provided with contiguous portions, including a central portion defined entirely by edges, and peripheral portions defined by edges and by a portion of a frontier of the ceiling. For the central portion, a capital is defined by facets that bear against the central portion edges and converge towards an apex, and a slender support column is centered on the apex and extends from the capital to a floor of the cavity. For each peripheral portion, a capital is defined by facets that bear against the peripheral portion edges and converge towards a terminal edge extending in a plane normal to a wall of the cavity, and a support rib extends in the normal plane between the terminal edge of the capital and a wall of the cavity. The method includes manufactured the part while making the above-defined supports and capitals by additive manufacturing.Type: ApplicationFiled: June 14, 2019Publication date: August 19, 2021Applicant: SAFRAN LANDING SYSTEMSInventors: Yves COURTOIS DE LOURMEL, Sébastien MESSE, Gérard BALDUCCI, Thierry CAULE

Patent number: 10808770Abstract: The invention relates to a system for the rotational decoupling of shafts, in particular drive shafts. The invention also relates to a generator protection system on a connection between a generator and a gas turbine engine. FIG. 1C illustrates the shaft-decoupling system in the decoupled position.Type: GrantFiled: September 13, 2017Date of Patent: October 20, 2020Assignee: SAFRAN ELECTRICAL & POWERInventors: Fernand Rodrigues, Yves Courtois De Lourmel

Patent number: 10618639Abstract: Drive equipment for rotating by friction an aircraft wheel equipped with a drive track and mounted to turn about an axis (X) on an axle of an aircraft undercarriage. The equipment comprise a base (22), a slide (24) mounted on the base on a sliding axis extending in a radial direction (R1, R1), a support (26) pivotable on the slide on an axis parallel to the rotation axis of the wheel; two rollers (21) rotatable on rotation axes parallel to the pivot axis; a central shaft (28) mounted for rotation on the support and being in engagement with the two rollers to provide their rotation; and an actuator (23A, 23B, 30) for moving the slide and the support between a disengagement position with the rollers distant from the wheel drive track and an engagement position with the rollers are held in contact with the drive track of the wheel.Type: GrantFiled: January 21, 2016Date of Patent: April 14, 2020Assignee: MESSIER-BUGATTI-DOWTYInventors: Frederic Martin, Yves Courtois de Lourmel, Maxence Wangermez, Mathieu Daffos, Pierre-Guillaume Phelut
