An igniter for a gas turbine engine comprising:
- a base;
- a glow plug heater rod extending from the base along an axis and terminating in a rod end;
- and a fuel receiver adjacent the heater rod, the fuel receiver extending axially between a closed end proximate the base and an open end proximate the rod end, the igniter seated from a fuel source of the gas turbine engine but for at the open end of the fuel receiver, the fuel receiver including a portion located closest to the heater rod, the rod end protruding axially relative to the axis from the fuel receiver portion located closest to the heater rod.
A gas turbine engine comprising:
- an inner liner and an outer liner defining a combustion chamber between the inner liner and the outer liner, one of the inner liner and the outer liner defining an igniter hole;
- and
- an igniter received within the igniter hole, the igniter having a base, a glow plug heater rod extending from the base along an axis and terminating in a rod end, and a fuel receiver adjacent the heater rod, the fuel receiver including a portion located closest to the heater rod, the rod end protruding axially relative to the axis from the fuel receiver portion located closest to the heater rod and protruding beyond the one of the inner liner and the outer liner into the combustion chamber.
