Patent number: 9556744Abstract: A turbomachine for an aircraft including at least one turbine driving rotation of a fan, and a jet nozzle coaxially extending a turbine and creating, with an outlet cone that terminates the turbine, a passage of annular cross section for combustion gases that pass through the turbine. The jet nozzle can be mounted so that it can move between two extreme positions for which under action of a controller, an annular cross section of the passage for the gases is respectively at its minimum or maximum, making it possible to vary the cross section according to phases of operation of the aircraft and distribute thrust between the fan and the jet nozzle.Type: GrantFiled: March 14, 2012Date of Patent: January 31, 2017Assignee: SNECMAInventors: Sebastien Dron, Nicolas Jerome Jean Tantot

Patent number: 8020831Abstract: A suspension for suspending of a turbine engine from the structure of an aircraft using a beam with an attachment device which attaches to the structure and at least one link rod articulated via one end to a journal secured to the beam and via the other to a fitting secured to the turbine engine is disclosed. This suspension is one wherein the journal is mounted on the beam via a flexible coupling formed of two preloaded laminated, elastomer and metal, cylinders.Type: GrantFiled: June 25, 2008Date of Patent: September 20, 2011Assignee: SNECMAInventors: Sebastien Dron, Gilles Lucien Fontenoy, Marc Patrick Tesniere

Patent number: 7909285Abstract: A suspension for suspending a turbine engine from the structure of an aircraft is disclosed. The suspension includes a beam with a first element including a first attachment unit which attaches the beam to the structure and a second element including a second attachment unit which attaches to the beam to the turbine engine. The beam further includes a first plate and a second plate. The plates are positioned transversely to the axis of the engine and joined together by a layer of elastomer. The first plate being secured to the first element and the second plate to the second element. This arrangement allows vibration damping between the engine and the structure of the aircraft.Type: GrantFiled: April 15, 2008Date of Patent: March 22, 2011Assignee: SnecmaInventors: Sebastien Dron, Gilles Lucien Fontenoy, Marc Patrick Tesniere

Patent number: 7566029Abstract: A suspension for suspending a jet engine on an aircraft strut includes a beam having a platform provided with fasteners for fastening the beam to the aircraft strut and arranged transversely with respect to a longitudinal axis of the jet engine. The suspension also includes first and second lateral links, the second lateral link being prolonged by a finger housed with clearance in a cavity provided in the beam so as to form a standby safety connection. The suspension further includes a central link. The finger extends between the platform and a pin of the central link in normal operation.Type: GrantFiled: March 27, 2006Date of Patent: July 28, 2009Assignee: SNECMAInventors: Sebastien Dron, Thibaut Guibert, Gregory Prudhomme, Marc Patrick Tesniere

Patent number: 7527220Abstract: A mount for an aircraft engine arranged to be attached firstly by a beam to the aircraft, and secondly by lateral and a median load transmission elements to the engine, the mount having an integrated load transmission and failsafe assembly arranged to ensure the continuity of load transmission in the event of failure of a load transmission element and to perform its failsafe function in unitary, concentrated fashion in the median zone of the mount. The mount is characterized by the fact that the load transmission and failsafe assembly includes an assembly of a female clevis with two wings and of a projecting element passing with clearance through the two wings of clevis, one being integral with the engine and the other with the mounting beam.Type: GrantFiled: March 24, 2005Date of Patent: May 5, 2009Assignee: SnecmaInventor: Sebastien Dron

Publication number: 20090032673Abstract: The present invention relates to a suspension for suspending a turbine engine from the structure of an aircraft, comprising a beam with a first element accepting means of attachment to said structure and a second element accepting means of attachment to the turbine engine. It is one wherein the beam comprises at least a first plate and a second plate, which plates are intended to be positioned transversely with respect to the axis of the engine and joined together by a layer of elastomer, the first plate being secured to the first element and the other plate to the second element. This arrangement allows vibration damping means to be incorporated in between the engine and the structure of the aircraft.Type: ApplicationFiled: April 15, 2008Publication date: February 5, 2009Applicant: SNECMAInventors: Sebastien DRON, Gilles Luchien Fontenoy, Marc Patrick Tesniere

Patent number: 7267301Abstract: An aircraft engine includes a mounting attached to an aircraft structure and transmitting forces between an engine casing and the aircraft structure. The mounting includes a fail safe assembly with a safety clevis with two lugs and a tab arranged between the two lugs. Either the clevis or the tab is fixed to an element of the engine casing and the other tab or clevis is fixed to the structure. A safety hinge pin is perpendicular to the axis of the engine and passes through the tab and the clevis, the two lugs and the tab being parallel to the engine axis.Type: GrantFiled: April 28, 2005Date of Patent: September 11, 2007Assignee: Snecma MoteursInventor: Sebastien Dron
