Abstract
FIELD: aircraft engineering. SUBSTANCE: antiflutter device is made in the form of airfoils 5, 6 mounted in the nose part of the engine nacelles 1 in a horizontal plane or in combination relative to the axis of symmetry of the engines. The area of the airfoils is 1-20% of the area of the outer surface of nacelle 1. EFFECT: reduced weight and increased critical flutter velocity at improved elastic vibration damping. 2 dwg
