FIELD: engines and pumps.
SUBSTANCE: claimed thrust reverser comprises deflectors and moving cowl arranged to displace relative to the fixed structure. Said fixed structure comprises the front frame and means for coupling with upstream part. Said moving cowl displaces between closed position whereat it ensures an aerodynamic integrity of the nacelle and deactivates said deflectors and open position whereat it opens the channel in the nacelle and activates said deflectors. Said front frame has deflecting edge including the element extending upstream to make a deformable board for aerodynamic coupling with appropriate upstream part whereto said front frame is secured. Said moving cowl has the part to ensure the coupling at closed position with said upstream part owing to diversion of said deformable board.
EFFECT: decreased disturbance in turbojet setting aerodynamics in straight thrust and reverse thrust modes.
