Abstract
A turbojet-engine thrust-reverser comprising pivoting hollow doors (3) which in the forward-thrust mode are integrated into the external cowling of the turbojet-engine and which in the thrust-reversal mode constitute scoop-type flow-deflecting baffles. A displaceable external cowling panel (20) covers both the fore frame (8) of the stationary structure and the cross-section of the flow exhaust of the door (3) when in the forward-thrust mode. The external cowling panel (20) is pivotable on a panel pivot (24) situated downstream of the pivot (9) of the door (3) and its upstream edge moves radially outward to simultaneously clear a space above the fore frame (8) and the exhaust cross-section for the deflected flow.
