TURBOMACHINE WHEEL Russian patent published in 2013 - IPC F01D5/30 F04D29/32 

FIELD: engines and pumps.

SUBSTANCE: wheel of a turbomachine, such as an aircraft jet turbine engine, includes at least one rotary disc that carries blades, and at least one ring made from composite material with a metal matrix. The ring is installed on the disc to take centrifugal forces during operation. It includes at least one ring-shaped flange formed with sectors. Sectors are located end-to-end and each of them includes a ring-shaped radial internal part and radial external part. Radial internal part is put on side surface of the disc; radial external part is borne against the ring to provide axial retention of the latter on the disc. The wheel also includes radial retention means of flange sectors on the disc. The other object of this invention is a turbomachine containing the above described wheel.

EFFECT: invention allows facilitating the flange installation at the rotary disc periphery and decreasing the stress in the ring.
