NOZZLE OF A GAS TURBINE WITH INTEGRALLY FORMED NOZZLES Russian patent published in 2022 - IPC F01D9/02 

FIELD: turbines.

SUBSTANCE: invention relates to a nozzle of a gas turbine. Nozzle of a gas turbine includes nozzles formed integrally from the end wall along the internal perimeter and the end wall along the external perimeter. The end wall along the internal perimeter has a connecting section on the upstream side and a connecting section on the downstream side. The connecting section on the upstream side extends radially inward and connects with the diaphragm along the internal perimeter. The connecting section on the downstream side, located downstream from the connecting section on the upstream side, extends radially inward and connects with the diaphragm along the internal perimeter. The end wall has a thin-walled section on the back edge section of the end wall along the internal perimeter, corresponding to a section of the back edge section of the end wall along the internal perimeter of a lower thickness.

EFFECT: voltage reduction associated with the temperature elongation caused by the increase in the temperature of the nozzle of a gas turbine, and therefore, voltage reduction occurring during thermal strain in the nozzle of a gas turbine.
