TORCH IGNITOR SYSTEM

A torch ignitor system (100) includes a torch wall (102) defining a combustion chamber (104) therein with a flame outlet (106) passing out of the torch wall (102) downstream of the combustion chamber (104). A fuel injector (108) is mounted to the torch wall (102) to issue fuel into the combustion chamber (104). At least one ignitor (110) is mounted to the torch wall (102), positioned to ignite fuel issued from the fuel injector (108). A film cooler (124) is defined through the torch wall (102) and is operative to issue a film of cooling air from outside the torch wall (102) along an interior surface (126) of the combustion chamber (104) for cooling the torch wall (102).
