A thrust reverser system for a turbofan engine, comprising: a stationary structure configured to be mounted to the turbofan engine and comprising a side beam extending therefrom; a transcowl mounted on the stationary structure and comprising a front edge, the transcowl configured for movement between a first position, in which the front edge abuts the stationary structure, and a second position, in which the transcowl is translated aft, thereby creating an aperture (402, 502) between the front edge and the stationary structure; a first displaceable blocker door at least partially surrounded by the transcowl, the first displaceable blocker door: (a) pivotally mounted to the side beam of the stationary structure at a pivot joint that provides a pivot axis, (b) rotatable about the pivot axis, (c) configured for pivoting, on the pivot axis, between a stowed position and a deployed position, and (d) configured, when it is in the deployed position, to direct engine airflow to discharge through the aperture to thereby generate reverse thrust, the first displaceable blocker door configured to trace out a path on an inner surface of the transcowl as it pivots between the stowed position and the deployed position, the inner surface having a contour formed therein to provide clearance for the displaceable blocker door as it pivots on the pivot axis; an actuation system coupled to the transcowl and the first displaceable blocker door, the actuation system configured to coordinate transcowl movement with pivoting of the first displaceable blocker door, thereby creating: (i) a forward position, in which the transcowl is in the first position and the first displaceable blocker door is in the stowed position, (ii) a reverse position, in which (a) the transcowl is in the second position and (b) the first displaceable blocker door is in the deployed position, and (iii) an intermediate position, in which (a) the transcowl is positioned at a predetermined distance between the first and second positions, thereby creating a reduced aperture through which a portion of engine airflow discharges, and (b) the first displaceable blocker door is in the stowed position. a stationary structure configured to be mounted to the turbofan engine and comprising a side beam extending therefrom;
