FIELD: aviation.

SUBSTANCE: aircraft has a body, a wing which left and right panels are designed to change the sweep angle. There is a mechanism for changing the sweep of the left and right wing panels, consisting of a power mechanism for turning the left and right wing panels and a mechanism for synchronizing the rotation of the left and right wing panels. The power mechanism for turning the left and right wing panels is made in the form of a screw jack with two drives, single for the left and right wing panels. It is designed to interact with the left pivoted wing panel by one end, and to interact with the right pivoted wing panel by the other end. The mechanism for synchronizing the rotation of the left and right wing panels is made in the form of a double-arm lever and two pull rods, while the rotation axis of the lever is fixed on the center wing section. One end of one of the pull rods is hingedly attached to the left pivoted wing panel, and the other end of this pull rod is hingedly attached to one of the arms of the above mentioned lever. One end of the second pull rod is hingedly attached to the right pivoted wing panel, and the other end of the second pull rod is hingedly attached to the second arm of the above mentioned lever.
