Patent number: 10036323Abstract: A rear nacelle assembly for turbojet engine includes an inner structure surrounding a downstream portion of the turbojet engine. In particular, the inner structure is movable in rotation between an operating position in which it forms a downstream fairing and defines an annular stream of cold air with a thrust reverser cowl, and a maintenance position in which the inner structure moves away from the downstream portion. A suspension pylon is further provided to mount the thrust reverser cowl and the inner structure. The thrust reverser cowl slides between an opening position clearing air flow deviation grids and a closing position recovering the air flow deviation grids. Moreover, the thrust reverser cowl is mounted on the suspension pylon by a pivot connection sliding around a main axis, and the inner structure is mounted on the suspension pylon by a pivot connection around the main axis.Type: GrantFiled: March 7, 2014Date of Patent: July 31, 2018Assignee: AIRCELLEInventors: Herve Hurlin, Nicolas Dezeustre, Olivier Kerbler

Patent number: 9482181Abstract: A jet engine nacelle has one thrust reverser device which includes a deflection means and one cowl translatable in a direction substantially parallel to a longitudinal axis of the nacelle. The cowl can translate between a closed position and an open position. In the open position, the cowl ensures the aerodynamic continuity of the nacelle and covers the deflection means. In the open position, the cowl opens a passage into the nacelle and uncovers the deflection means. The thrust reverser device moreover includes one blocking flap pivotably mounted by one end attached to a rear portion of the deflection means, and slidingly connected to the moving cowl. The pivoting end is also translatably connected to the rear portion of the deflection means.Type: GrantFiled: May 2, 2013Date of Patent: November 1, 2016Assignee: AIRCELLEInventors: Herve Hurlin, Olivier Kerbler, Nicolas Dezeustre, Loic Le Boulicaut

Patent number: 9279385Abstract: A nacelle for an aircraft bypass turbojet engine includes downstream, an internal stationary structure surrounding part of the bypass turbojet engine, and an external structure surrounding the internal stationary structure, defining an annular flow path along which an air flow circulates. The external structure includes a mobile flap disposed at the downstream end of the external structure and positioned facing the annular flow path. Each mobile flap can rotate such as to move into a position that increases or reduces the height of the cross-section of the annular flow path in relation to an idle position, in response to the pressure exerted on the mobile flap by the air flow circulating through the facing annular flow path. The mobile flap can return from the cross-section-increasing or -reducing position to another position under the effect of an elastic return means.Type: GrantFiled: December 2, 2013Date of Patent: March 8, 2016Assignee: AIRCELLEInventors: Nicolas Dezeustre, Patrick Stella

Patent number: 9133790Abstract: A propulsion system has a nacelle, and inside this nacelle, a dual flow turbojet engine includes a fan case in which are located a fan and an assembly of fixed flow-rectifying vanes. This propulsion system includes a thrust inverter located between the fan and the assembly of the fixed flow-rectifying vanes. In particular, the thrust inverter includes a plurality of windows formed in the fan case and thrust inversion flaps to send back the secondary airflow toward the outside and toward the front of the nacelle, through the windows. The thrust inversion flaps pivotally move between a normal operating position in which they allow the passage of the secondary airflow and block the windows, and a thrust inversion position in which they block the passage and clear the windows.Type: GrantFiled: March 10, 2011Date of Patent: September 15, 2015Assignee: AIRCELLEInventors: Ingrid Pitiot, Nicolas Dezeustre
