Patent number: 9157334Abstract: A turbomachine for an aircraft including a mechanism forming a case fitted in a rear extension of an inner ferrule of an intermediate casing, and positioned around a central casing. The mechanism includes a structural upstream ferrule assembled on the inner ferrule and defining a front portion of a surface internally delimiting a secondary vein, and a main case extending on the upstream ferrule towards the rear. The turbomachine further includes a structural mechanism rigidifying the central casing, surrounded by the case, and extending towards the rear between the upstream ferrule and the central casing on which these mechanisms are assembled.Type: GrantFiled: November 2, 2010Date of Patent: October 13, 2015Assignee: SNECMAInventors: Audrey Grede, Jacky Raphael Michel Derenes, Clarisse Savine Mathilde Reaux, Guilhem Seize

Turboshaft engine attached to a pylon of the fuselage of an aircraft by a failsafe suspension system
Patent number: 9067688Abstract: A suspension system including a front suspension plane located at an intermediate turboshaft engine casing and connecting same to a pylon, a rear suspension plane located at an exhaust casing of the turboshaft engine and connecting same to the pylon, and a failsafe intermediate suspension plane located between the front and rear planes and including at least one connecting rod connecting the turboshaft engine having a structural outer casing to the pylon, the connecting rod mounted on the turboshaft engine with a predetermined clearance that renders the connecting rod inoperable while the suspension system of the rear plane is operating. The connecting rod is advantageously arranged between the outer casing and the pylon, and an element made of a flexible material is combined with the connecting rod to create the predetermined clearance by an elastically deformable nature thereof.Type: GrantFiled: June 9, 2011Date of Patent: June 30, 2015Assignee: SNECMAInventors: Francois Bellabal, Guilhem Seize, Thomas Vincent -

Patent number: 8600611Abstract: A system for measuring fatigue of a component of an aircraft subject to mechanical stresses includes: a plurality of stress sensors mounted on the component, each sensor being configured to detect a predetermined mechanical stress threshold and to deliver a data signal representative of exceeding of the threshold; and a mechanism for recording the data and the sensors configured to detect different stress thresholds so as to make it possible to calculate, on the basis of the data recorded by the system, an estimation of fatigue of the component due to the mechanical stresses. It is thus possible to optimize overhaul of the components.Type: GrantFiled: November 15, 2010Date of Patent: December 3, 2013Assignee: SNECMAInventor: Guilhem Seize
