Fan air of turbo-fan engine flows through ducts which pass through wall of lobed thrust nozzle mounted on aft end of the engine so as to receive exhaust gas discharged therefrom, the ducts terminating within the nozzle and being spaced apart circumferentially thereof. Assembly may include a tubular ejector movable from position around nozzle to position downstream therefrom and provided with thrust reversing doors, or a pair of thrust reversing doors movable from position adjacent aft end of housing which surrounds the engine to position downstream from the nozzle.
