AXIAL-FLOW TURBOMACHINE RUNNER Russian patent published in 2007 - IPC F01D5/30 

FIELD: gas-turbine engines including axial-flow turbomachine runners.

SUBSTANCE: proposed axial-flow turbomachine runner has turbine disk with blades. Roots of blades are secured in axial direction in longitudinal slots of turbine disk by means of pin locks inserted in ports disposed over circumference. These ports are formed by transverse grooves on longitudinal projections of blade roots and by groove on longitudinal annular clamp of disk aligned with them. Mentioned longitudinal slots cross annular clamp of disk and its groove all the way through groove depth down to its bottom surface. So, blade roots are reliably locked in runner of small-size turbomachine operating at high temperatures, gas-dynamic and centrifugal thrusts.

EFFECT: enhanced manufacturability of parts and facilitated assembly-disassembly of turbomachine runner.
