SYSTEM FOR REGULATING FUEL SUPPLY TO AFTERBURNER OF TURBOJET ENGINE Russian patent published in 2021 - IPC F02C9/28 

FIELD: aircraft engine construction.

SUBSTANCE: invention relates to the field of aircraft engine construction, in particular to systems for regulating the fuel supply to the afterburners of aircraft turbojet engines (turbojet engine with afterburner and turbojet dual-circuit engine with afterburner). A fuel supply system is proposed for the afterburner of a turbojet engine, which contains a control unit, a fuel tank, an afterburner pump, an afterburner fuel flow regulator, and a distributor that directs fuel to the first collector with flame stabilizers, the second collector and the third collector, depending on the gas pressure in the afterburner and the specified engine mode. At the same time, a shut-off valve is installed behind the distributor in the pipeline of the second collector, which opens and closes at the commands of the control unit when the set pressure values in the second and third collectors are reached, providing the fuel flow and pressure necessary for the uniform distribution of the fuel-air mixture along the afterburner section.

EFFECT: task of the invention is providing high quality and uniform spraying of afterburner fuel to improve engine control and increase the stability of the engine in afterburner modes.
