FIELD: mechanical engineering; turbojet engines.
SUBSTANCE: invention relates to interblade pads for support disks of fan blades. Proposed support disk contains great number of interblade pads installed between pairs of adjacent blades. Each interblade pad contains central part and two side parts. Central part is made for rigid connection with support disk between two adjacent blades featuring first deformation resistance. Side parts are extensions of two side edges of central part, each being made for deflection under action of stroke of blade arranged opposite to said part and featuring second deformation resistance less than said first deformation resistance. Side parts are made of memorized shape effect material.
EFFECT: reduced damage to fan blades by foreign objects accidentally getting into turbojet engine.
