FLAME STABILIZER OF AFTERBURNER OF GAS TURBINE ENGINE Russian patent published in 2023 - IPC F23R3/18 

FIELD: aviation gas turbine engines.

SUBSTANCE: invention relates in particular to afterburners for turbojet engines, including flame stabilizers manufactured by casting or selective laser melting. The flame stabilizer of the afterburner chamber of a gas turbine engine contains stabilizers made in a T-shape, which are subsequently assembled into a ring, radial and ring carburetors made by casting or selective laser fusion. The carburetors are fixed at two points, while in the area of the air intakes they are stationary, and the second point of attachment to the stabilizer is made floating to compensate for the difference in temperature expansion of materials by making oval holes in the stabilizer and fastening the carburetors in them using pins permanently attached to the carburetors and rings, attached to the pins, but without attachment points to the stabilizer.

EFFECT: providing compensation for temperature expansions (temperature decoupling) between the stabilizer and carburetors, the ability to replace carburetors without replacing the stabilizer to ensure maintainability, as well as to ensure easy repair of the afterburner (front device) by quickly replacing the stabilizer.
