Patent ID: 8448420

Claim:
An aircraft nacelle in which a power plant is arranged, comprising: a duct ( 16 ) in which a flow that is able to assist thrust is able to flow; at least one stationary part ( 28 ); at least one moving part ( 30 ) that can occupy a first position in which the at least one stationary part ( 28 ) and the at least one moving part ( 30 ) are contiguous, and the at least one moving part ( 3 ) is configured to move translationally in a longitudinal direction so as to provide a radial opening ( 32 ) after translational motion; a device for reducing, canceling, or reversing the thrust that comprises at least one flap ( 34 ) that can occupy at least one so-called active position in which the at least one flap deflects—in a direction of a radial opening ( 32 )—at least a portion of the flow that is able to assist the thrust and another at-rest position in which said flap ( 34 ) does not interfere with the flow that can assist the thrust, wherein a wall of the nacelle delimiting the duct in which the flow to be deflected flows comprises the at least one moving part that can occupy two positions, a first position in which it is interposed between the flow to be deflected and the flap ( 34 ) and another position in which it releases the flap ( 34 ) so as to allow said flap to change position and to move from the at-rest position to the active position, each flap ( 34 ) comprises means for articulation ( 40 ) with a first pivoting axis ( 42 ) arranged at a first end called an upper end of the flap ( 34 ) and in an upper part of the nacelle and a second pivoting axis ( 44 ) arranged at a second end called a lower end of the flap ( 34 ) and in a lower part of the nacelle, and said pivoting axes ( 42 , 44 ) are essentially parallel to a vertical median axis ( 26 ) of the nacelle.
