The invention concerns a turbofan thrust reverser comprising an annular assembly of pivoting flaps (12) closing a channel (17) circulating the flow and a turning vane assembly (20) deviating the reversed flow, covered in direct jet by a cowling (7) mobile in translation. On each peripheral sector, a first vane part (21) is fixed and at least a second vane part (22) is mobile, radially superposed on the first vane part (21) in direct thrust and after axial translation in the turbojet longitudinal direction, the second part (22) is juxtaposed with the first part (21).
Un inverseur de poussée de turboréacteur à double flux comporte un ensemble annulaire de volets pivotants (12) d'obturation du canal (17) de circulation du flux et un ensemble de grilles d'aubages (20) de déviation du flux inversé, recouverts en jet direct par un capot (7) mobile en translation. Sur chaque secteur périphérique, une première partie (21) de grille est fixe et au moins une seconde partie (22) de grille est mobile, placée en superposition radiale de la première partie (21) de grille en poussée directe et après translation axiale dans la direction longitudinale du turboréacteur, la seconde partie (22) est juxtaposée à la première partie (21).
