IMPROVED FLANGE FOR CONNECTING AXIAL COMPRESSOR AND HIGH PRESSURE STEP ROTOR DISK UNIT IN GAS TURBINE Russian patent published in 2007 - IPC F04D29/60

Abstract RU 2300670 C2

FIELD: flanges for connecting axial compressor to gas turbine rotor disk unit.

SUBSTANCE: in accordance to invention flange has body in form of truncated cone, which is connected to axial compressor shaft by means of a hub, which has cylindrical configuration and which by greater base of truncated cone of body is connected to unit by means of hub shelf in form of circular ring, and a circular recess is made in the shelf surface facing the rotor disk unit, connected to corresponding shelf made on rotor disk unit; body has external generatrix which is inclined relatively to direction, oriented at straight angles to axis (X), at angle α₁ ranging from 25° to 35°, and internal generatrix which is inclined at angle α₂ ranging from 12° to 18°, making it possible to decrease voltage concentrations.

EFFECT: increased rotation speed and level of compression in turbines for increased temperature of flowing substance or for determining appropriate combination of aforementioned two aspects.
