FIELD: mechanical engineering; turbomachines for aircraft.
SUBSTANCE: invention relates to rotors of turbomachines used, particularly, in aviation, in which drum 124 in form of cylindrical solid of revolution rotation around longitudinal axis is manufactured of metal alloy, and it has curvilinear profile between front and rear ends 124b. Said profile is formed by ring shell arranged around said longitudinal axis, being located in radial direction to both sides from surface of rotation, with generatrix 134. Rear end 124b is provided with stiffening element. Said stiffening element is provided with at least one composite element 140 fitted on rear end 124b of drum and having fibers, and matrix made of polymeric material. Drum is designed for forming rotor of low-pressure compressor.
EFFECT: enlarged operating capabilities.
