Thrust reverser and nacelle for aircraft equipped with at least one such reverser

A thrust reverser for double-flow nacelle that has a cowling, with said thrust reverser having an internal door and an external door designed to be made within the thickness of said cowling, and means for simultaneously displacing said doors between a first position called the rest position, in which said doors are integrated into said cowling so as to form an aerodynamic continuity with the external wall and the internal wall of said cowling, and a second active position, in which said doors are open so that said internal and external doors extend toward the inside and toward the outside of the nacelle, respectively, thus at least partially blocking the annular channel of the secondary flow, to deflect the secondary flow and to generate a thrust reversal, wherein said means of displacement of said doors comprise

• means for sliding along a shaft essentially parallel to the principal axis of the nacelle, with the extremities of said means being designed to be linked to pivot at one extremity of said doors,
• with each of the doors being linked also to said shaft through at least two intermediate pivoting arms whose extremities are hinged respectively to the door and to the shaft so that the sliding of said means along said shaft causes the displacement of the doors between the two positions, and in that said means of displacement are arranged relative to the doors so that they are made to be received in a compartment in said cowling formed by the doors in the rest position.
