LASER-IGNITION COMBUSTOR FOR GAS TURBINE ENGINE

The combustor has a laser ignitor mounted to the casing, remotely from the liner of the combustion chamber. The laser ignitor has an igniter beam path for igniting the fuel and air mixture in the combustion chamber, the igniter beam path extending at least partially across the air plenum surrounding...

Beschreibung
Zusammenfassung:	The combustor has a laser ignitor mounted to the casing, remotely from the liner of the combustion chamber. The laser ignitor has an igniter beam path for igniting the fuel and air mixture in the combustion chamber, the igniter beam path extending at least partially across the air plenum surrounding the liner and into the combustion chamber through a corresponding beam path aperture provided in the liner. La chambre de combustion comporte un allumeur laser monté sur le boîtier, à distance de la chemise de la chambre de combustion. Lallumeur laser a un trajet de faisceau dallumeur pour allumer le mélange de carburant et dair dans la chambre de combustion, le trajet de faisceau dallumeur sétendant au moins partiellement à travers le plénum dair entourant la chemise et dans la chambre de combustion à travers une ouverture de trajet de faisceau correspondante disposée dans la chemise.
