A thrust reverser system including a reverse thrust airflow duct (44) extending through an outer structure (46) of an aircraft engine aft nozzle (32) is disclosed. The reverse thrust duct (44) connects a nozzle exhaust duct (34) with the surrounding atmosphere (46). The duct (44) includes an inlet (72) and an outlet (70). A plurality of slats (50) are located within the reverse thrust duct to direct nozzle exhaust (38) from the nozzle exhaust duct (34) in an outward and/or forward direction. One or more outer doors (54) are formed near the outer structure exterior surface (90) for closing off the reverse thrust duct outlet (70) to the atmosphere. One or more inner doors (56) are provided for closing off the duct inlet (72) at the exhaust duct (34). An actuation system moves the inner and outer doors (56), (54) between open and closed positions. In the open position, the inner and outer doors (56), (54) are moved away from the duct (44) to open the airflow duct inlet and outlet. A portion (98) of the inner door blocks off the nozzle exhaust duct (34) by moving aftward to contact a nozzle centerbody (36). The exhaust air (38) is forced to exit the nozzle (32) via the duct (44) causing reverse thrust.
