Beschreibung
Zusammenfassung:	A torch ignitor system includes a torch wall defining a combustion chamber therein with a flame outlet passing out of the torch wall downstream of the combustion chamber. A fuel injector is mounted to the torch wall to issue fuel into the combustion chamber. At least one ignitor is mounted to the torch wall, positioned to ignite fuel issued from the fuel injector. A film cooler is defined through the torch wall and is operative to issue a film of cooling air from outside the torch wall along an interior surface of the combustion chamber for cooling the torch wall.
