Abstract
An exciter circuit for a gas turbine engine delivers a first single high-energy spark followed by subsequent sparks of relatively lower energy to ensures start reliability by specifically clearing ice build-up at the ignition plugs.
Claims5
An ignition system for a gas turbine engine comprising:
- an exciter controller;
- an ignition plug;
- and
- an ignition exciter to drive said ignition plug, said ignition exciter in communication with said exciter controller, said ignition exciter including an exciter circuit with a capacitor and a resistor divider connected to a comparator to generate a multiple of low-energy sparks subsequent to a first single high energy spark.
