COMPONENT OF TURBO-MACHINE WITH COOLING ELEMENTS AND METHOD FOR MANUFACTURING AND OPERATING INDICATED COMPONENT OF TURBO-MOTOR Russian patent published in 2018 - IPC F01D25/14 F23R3/00 

FIELD: turbines or turbomachines.

SUBSTANCE: invention relates to component (1) of turbomachine, in particular to component of gas turbine combustion chamber, or nozzle component, comprising housing (2) with first (20), second (21) and third (22) sections, wherein first, second and third sections (20, 21, 22) are formed as single part and are made of same material, end surface (23) of first section (20) of body (2), while end surface (23) during operation of turbine is exposed to first temperature, higher than second temperature of cooling fluid. Second section (21) is located between first section (20) and third section (22), and is partially formed as lattice structure (25). This lattice structure (25) comprises plurality of strut-shaped struts (30), with each strut from first set of multiple struts (30) having first end (31), this first end (31) joining first section (20), and free space (35), which is pierced by multitude of struts (30), while free space (35) provides at least one passage for fluid through which cooling fluid can be directed through inside of second section (21) during operation of turbomachine. Invention also relates to method of manufacturing such component (1) of turbomachine, comprising steps of creating component (1) of turbomachine, as previously defined, as component formed as single part using manufacturing techniques by layer-by-layer synthesis, in particular, selective laser sintering, or selective laser melting, or melting with electron beam. In addition, method of operating gas turbine nozzle component (1) is presented.

EFFECT: invention provides improved cooling in combustion chamber.
