Patent ID: 8109468

Claim:
Aircraft nacelle comprising: a cowling of longitudinal axis, an engine housed in an interior space delimited by the cowling, an annular channel surrounding the engine and intended to receive a secondary flow, the cowling comprising: a fixed portion, a mobile portion able to slide according to an axis substantially parallel to the longitudinal axis in order to define a radial opening between the mobile portion and the fixed portion, a thrust reverser system comprising a plurality of interior flaps mounted rotatably mobile and able to have a rest position, wherein the interior flaps are substantially parallel to the longitudinal axis, and able to have a deployed position wherein the interior flaps obstruct at least partially the annular channel, the mobile portion of the cowling comprising an annular housing centred on the longitudinal axis, and extending longitudinally in order to receive the interior flaps in the rest position, each flap of the thrust reverser being linked to the fixed portion by at least one pivot joint of axis orthogonal to the longitudinal axis, said pivot joint being accomplished by an axis crossing longitudinal ends of two longitudinal bars fixed to the fixed portion surrounding laterally a first longitudinal end of the flap, and the flap, each flap being also linked to the mobile portion by at least one sliding-pivot joint including a sliding pivot and a sliding rail, the axis of the sliding pivot being substantially parallel to the axis of the pivot joint linking the flap to the fixed portion, and the axis of the sliding rail being orthogonal to the axis of the pivot joint and being contained in a plane substantially parallel to a plane containing the longitudinal axis, in such a way that a sliding of the mobile portion in separation from the fixed portion provokes a rotation of each flap around the axis of rotation of the pivot joint with the fixed portion, the control of the position of the flaps being obtained as such directly by sliding of the mobile portion of the cowling.
