FIELD: motors and pumps.
SUBSTANCE: thrust reverser of the jet turbine engine nacelle contains deflecting elements and movable cowling including at least one flap installed on the movable cowling with the possibility of rotation. The movable cowling is made with possibility of movement from the closed position to opened position, and is equipped with drive-screw having slot in at least part of its length. The drive-screw slot is made with possibility of interaction with fixed guiding device of the nacelle to ensure the drive-screw rotation during translational movement of the movable cowling. The drive-screw is linked with movement transfer device of the flap drive system. The drive-screw slot is made spiral and has section of lost motion ensuring the drive-screw lost motion at the beginning of the movable cowling opening.
EFFECT: invention simplifies and reduces weight of the flap drive system of the thrust reverser.
