LOW PRESSURE TURBINE SUPPORT Russian patent published in 2018 - IPC F01D25/16 F01D25/12 

FIELD: engine building.

SUBSTANCE: invention relates to turbine supports of gas turbine engines for aviation and ground applications. Support of the low-pressure turbine is made with radial power struts placed in the fairings, installed in the gas path of the turbine. Firings of the power pillars of the support are made with the front, middle and rear cavities and with a symmetrical external profile, with the angle of inclination of the axis of symmetry of the external profile of the fairing relative to the radial plane, equal to 10…50 degrees. Power racks are installed in the middle cavity of the fairing, the middle cavity of each fairing being configured to pass cooling air to cool the power racks installed in said cavity. Power racks are made with a cylindrical inner surface that forms an internal cavity, and with cylindrical and flat surfaces of the outer surface, with the formation of slotted air cavities between the outer flat side surfaces of the power column and the internal flat side surfaces of the walls of the middle air cavity of the fairing.

EFFECT: invention makes it possible to increase the efficiency of cooling the power racks with a minimum consumption of cooling air for cooling the pillars of the low-pressure turbine.
