Abstract
The disclosure describes a fuel scheduling system that controls the fuel into the pilot burner of an afterburner by making fuel flow directly proportional to compressor discharge pressure at low compressor pressures, but to limit fuel flow to a fixed value at high A/B pressures. This is accomplished by used of a fixed orifice trim in combination with a variable orifice inserted in the fuel tube for the afterburner.
