FIELD: dual-flow turbojet engines. SUBSTANCE: device has moving members integrated in primary casing of turbojet engine when running under direct thrust conditions and forming obstacles deflecting secondary gas flow when it is running under thrust reversal conditions. Each moving member rests on adjustable pins rigidly coupled with fixed structure of primary casing. Each member is formed by external panel turning under the action of actuating ram mounted on primary casing that provides for appropriate airfoil of this primary casing in case of direct thrust and by internal panel which abuts against mentioned external panel in case of direct thrust and can slide along mentioned external panel during thrust reversal thereby ensuring deflection of gas flow being reversed. EFFECT: improved design. 4 cl, 5 dwg
