ROTARY FLAME STABILIZER OF ADAPTIVE AFTERCAJER OF DOUBLE-CIRCUIT GAS TURBINE ENGINE Russian patent published in 2022 - IPC F23R3/22 

FIELD: aviation.

SUBSTANCE: invention relates to the field of aviation, more precisely, to gas turbine engines with an adaptive afterburner (AAB). The rotary flame stabilizer of the adaptive afterburner of the bypass gas turbine engine comprises a housing with an air-fuel mixture supply channel and a perforation in the downstream wall, a hinged assembly for suspension to the afterburner housing, made in the root part of the housing, a window for air-fuel mixture inlet. The air-fuel mixture inlet window is placed in the region of the root part of the stabilizer body, while the air-fuel mixture supply channel behind the mentioned window is made symmetrically bifurcating into side channels converging in the end part. The axes of the side channels in the central part are located radially for the stabilizer fixed in the working position, the stabilizer is equipped with a lever in the area of ​​the root part of the body, pivotally connected to the drive mechanism, while on the body of the afterburner, in front of each stabilizer, a nozzle is fixed, the outlet is directed to the area of ​​the corresponding window for inlet of the air-fuel mixture of the stabilizer, fixed in the working position. At the end part of the stabilizer there is at least one opening of the passage section enlarged in comparison with the perforation of the rear wall.

EFFECT: invention provides for a reduction in the mass of attachment points and drives, as well as a reduction in gas-dynamic losses in the gas path and visibility in the radar and infrared ranges in non-afterburning mode.
