Abstract
A bypass jet engine which includes a confluent nozzle (8) and a thrust reverser (7), controlled means (14) arranged at the periphery of the confluent nozzle (8) adjacent to the mouth of an annular bypass duct (4) and inside this nozzle to vary the confluence cross section. The bypass jet engine also includes means of shifting the pivot pins (20) of the reverser doors (7) in order to reduce the cross section of the outlet orifice of the nozzle when the controlled means (14) of varying the confluence cross section increase the confluence cross section and, conversely, to increase the cross section of the outlet orifice of the nozzle when the controlled means (14) reduce the confluence cross section.
