FIELD: aircraft industry; double-flow turbojet engines. SUBSTANCE: device has turnable flaps 7 integrated at forwards thrust in outer wall of engine nacelle and forming, at reverse thrust, deflectors for gas flow after being turned by drive lift. Front panel 20 in direction of flow backs up each flap 7 from inner side and is hinge mounted on the same axle 27 of rotation as turnable panel 7. Coupling means between turnable flap 7 and front panel 20 in direction of flow are formed by epicycloidal gear train consisting of toothed member 31 rigidly coupled with turnable flap 7, outer toothed rim 34 rigidly coupled with front panel 20 in direction of flow and at least one freely turning gear 33 rigidly coupled with fixed structure and forming a planet pinion. EFFECT: enhanced aerodynamic characteristics at forward thrust. 4 cl, 11 dwg
