A translating sleeve structure for a cascade type thrust reverser system for controlling fan air for a turbofan aircraft gas turbine jet engine, such translating sleeve having a plurality of circumferentially arranged spaced blocker doors, each of which is hingedly connected to a door receptacle bonded into a single layer honeycomb panel inner wall of the sleeve at a longitudinal position which is aft of bleed ports positioned in the core cowl of the engine for periodically expelling gases from the engine at elevated temperatures and pressures. Positioning such blocker doors aft of the bleed ports precludes injury to the blocker doors or to their hinged connections to the core cowl and permits smaller uniformly sized doors to be used. A fan air flow deflector positioned at the leading inner portion of the inner wall of the translating sleeve assists in turning the flow of the reversed fan air through a cascade structure and access doors provided in the sleeve are vented to permit any fan air that may enter the interior of the sleeve when it is deployed to vent to the exterior without any air pressure buildup within such sleeve.

[ What is claimed is:] [1.] In a cascade type thrust reversing system for controlling fan air from a fan gas turbine jet engine for an aircraft, said engine having a core cowl that is provided with bleed port means positioned aft of a fixed fan cowl structure, the combination comprising:a forward fixed structure having inner and outer walls positioned immediately aft of the fixed fan cowl structure;a translatable sleeve structure, having inner and outer walls, that is positioned in an abutting position in a stowed position to said forward fixed structure, the inner wall of said sleeve structure being provided with a plurality of circumferentially arranged deployable blocker doors that are horizontally positioned in said inner wall aft of said bleed port means, andtranslating means for translating said translating sleeve structure rearwardly to deploy said blocker doors into abutting contact with the core cowl and thereby block the fan air and redirect it outwardly through an annular space provided between said forward fixed structure and the translated sleeve structure.
