Abstract
The prompt starting of a gas turbine engine is achieved, even when utilizing comparatively poor grade fuel with relatively high viscosity, by modulating the fuel flow between high and low flow rates during the ignition portion of a start schedule. The fuel flow modulation is accomplished by delivering a pulse width modulated control signal to a fuel metering device and modulation is terminated when ignition is verified.
