HEAT-SHIELD MANIFOLD SYSTEM FOR MIDFRAME CASE OF GAS TURBINE ENGINE Russian patent published in 2018 - IPC F01D25/26 F02C7/12 

FIELD: machine building.

SUBSTANCE: invention relates to gas turbine engines, and more particularly to cooling fluid supply systems in gas turbine engines. Disclosed is heat-shield manifold system (10) for inner casing (12) between compressor (14) and turbine assembly (16). Heat-shield manifold system (10) protects outer casing (18) from the high-temperature pumping air of the compressor, which ensures the manufacture of outer casing (18) extending between compressor (14) and turbine assembly (16), from less expensive materials that would otherwise be necessary. In addition, heat-shield manifold system (10) can be designed in such a way that the compressor bleed air is passed from compressor (14) to heat-shield manifold system (10) without passing through a conventional inter-flange connection that may leak.

EFFECT: heat-shield manifold system for the casing of the central frame of the gas turbine engine has been proposed.
