The invention relates to a bypass turbojet engine having pivoting, hollow thrust reverser doors which, in the forward thrust configuration, are integrated into the external engine cowling and which, in the reverse thrust configuration, constitute scoop baffles that deflect exhaust air flow. A movable deflector baffle cooperates with each door such that, when the door is opened towards a thrust reversing direction, the baffle moves above an outer surface of the outer panel of the door in such a way that undesired interference between the exhaust flow moving through the door and the flow deflected by the outer surface of the door is minimized or avoided.

[ We claim:] [1.] A thrust reverser for a bypass type turbojet engine that includes a cowling and a bypass or exhaust flow duct within the cowling, comprising;hollow thrust deflector scoop doors forming part of the cowling when in a closed position and dipping at their upstream ends into the bypass flow stream when pivotally actuated into the bypass flow duct to thereby deflect bypass flow along outer surfaces of the doors outwardly through openings created in the cowling by the pivoting motion of each of the doors into a respective thrust reverse position, the doors also including inner ducts forming deflector scoops that further deflect bypass flow outwardly when the doors are pivoted into said respective thrust reverse positions;movable flow deflecting baffles associated with each door; andbaffle motion control devices associated with each door and arranged to move each baffle above the outer surface of its associated door when the door is pivoted to its thrust reverse position, each baffle directing flow of the bypass stream deflected by the associated door in such a manner as to minimize or eliminate aerodynamic interference between deflected bypass flow moving through the door and bypass flow deflected by the outside surface of the door.
