Abstract
Abstract A turbomachine rotor of alternating bladed rings and spacer rings, the bladed rings including blades welded to a rim, a web extending radially inward from the rim, and flanges extending from both faces of the web, with a reinforcing ring of filament reinforced composite material serving to resist centrifugal forces on each flange.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
102 words
A turbomachine rotor comprising, in combination, bladed rings, spacer rings disposed between and abutting adjacent bladed rings, and means retaining the bladed rings and spacer rings fixed together in abutting relation to form a drum rotor; each bladed ring comprising an axially extending rim bearing a ring of blades extending radially outward from the rim, a web integral with the rim extending radially inward from near the middle of the rim, a flange integral with the web extending axially from each face of the web, and a reinforcing ring of filament reinforced composite material disposed around the outer surface of each flange.
