Abstract:
1. An aircraft jet engine comprising a nozzle ( 1 ) ejecting a propulsion jet, or comprising the confluence of two propulsion jets, said nozzle ( 1 ) having one or two output rings ( 2 ) which comprise means of disturbing said propulsion jet or jets consisting of at least one pair ( 3 to 10 ) of conduits ( 3 a , 3 b , . . . , 10 a , 10 b ) via which jets of air are ejected, said conduits ( 3 a , 3 b , . . . , 10 a , 10 b ) opening at the output of said nozzle ( 1 ), the conduits ( 3 a , 3 b , . . . , 10 a , 10 b ) of each pair ( 3 to 10 ) being disposed convergent with respect to each other in order to generate at the output a region of interaction of the air jets, wherein the conduits ( 3 a , 3 b , . . . , 10 a , 10 b ) of each pair ( 3 to 10 ) converge towards each other at the output of said nozzle ( 1 ) with an angle of convergence lying between 40 degrees and 70 degrees.
