FIELD: airpower.
SUBSTANCE: in the method for controlling the aircraft turbojet engine with the afterburner combustion, the engine is tested in the forced mode with the given altitude and the Mach number, for which the fuel flow through the fuel manifolds of the afterburner changes by the n-th number of times and forms the n-th number of programs for maintaining fuel consumption through the afterburner fuel manifolds. Then, for each program, the expansion ratio on the turbine is changed to achieve a thrust value corresponding to the specified altitude and the Mach number, and the total fuel consumption is measured. Further, the results are compared, the lowest total fuel consumption is extracted, then the program with the lowest total fuel consumption is used for the flight of the aircraft in the forced mode with the given altitude and the Mach number.
EFFECT: invention allows to reduce fuel consumption on the forced mode of the engine operation.
