DEVICE FOR FASTENING THE FLAME STABILIZATION SYSTEM TO THE BODY OF THE AFTERBURNER COMBUSTION CHAMBER OF A TURBOFAN ENGINE Russian patent published in 2023 - IPC F23R3/18 

FIELD: aircraft engine building.

SUBSTANCE: design of afterburner elements of turbofan engines (TFE). The device for fastening the flame stabilization system to the body of the afterburner combustion chamber of a turbofan engine, while the engine is made bypass, and the device contains power rods, which at one end are pivotally connected to the afterburner housing bracket, and at the other end are pivotally connected to the flame stabilizer bracket, while the afterburner contains a heat shield that forms a cooling channel between the afterburner body and the heat shield itself. Power rods consist of two parts joined by a threaded connection, each of which has a longitudinal through channel with inlet and outlet holes, while the inlet of the rod part pivotally connected to the afterburner housing bracket is located in the cooling channel. At the end section of the other part of the rod, in the place of its hinged connection with the stabilizer bracket, a guide protective visor is installed.

EFFECT: reduction in the thermal load on the flame stabilizer and the place of its attachment to the thrust, which increases their resource and increases the reliability of the engine structural elements as a whole.
