A dual-flow thrust reverser for a turbine engine comprises pivoting doors (2), integrated with the outer wall of the efflux duct in forward thrust and constituting efflux deflecting obstacles in reverse thrust. At least one door (2) comprises in the downstream zone a passage (12) of which the geometry is designed to allow efflux to escape at controlled rate and direction when operating in reverse thrust, means (10) of obstructing the said passage (12) when operating in forward thrust so as to ensure continuity of the radially exterior surface (18) of the efflux duct (15).
Un inverseur de poussée de turboréacteur à double flux comporte des portes (2) pivotantes, intégrées en jet direct dans la paroi extérieure du conduit de flux et constituant des obstacles de déviation de flux en inversion de poussée. Au moins une porte (2) comporte en zone aval un passage (12) dont la géométrie est adaptée de manière à autoriser un flux de fuite d'un débit et de direction contrôlés lors du fonctionnement en inversion de poussée, des moyens (10) obturant ledit passage (12) lors du fonctionnement en jet direct de manière à assurer la continuité de la surface (18) radialement extérieure du conduit (15) de flux.
