Abstract
Methods and associated devices useful for the health monitoring of igniters of gas turbine engines are disclosed. Exemplary embodiments disclosed include the use of an accumulated spark count to an igniter to obtain an indication of wear on the igniter and/or the remaining life of the igniter. An exemplary method disclosed includes: receiving one or more signals indicative of a commanded spark count to the igniter for one or more ignition events; processing the one or more signals indicative of the commanded spark count to the igniter, determining a total accumulated commanded spark count to the igniter; and generating one or more signals indicative of at least one of an estimated wear on the igniter or an estimated remaining life of the igniter based on the total accumulated commanded spark count to the igniter.
