Patent

CA 2225376

A method of reducing pressure fluctuations in the combustor of a gas turbine engine resulting from the combustion of fuel and air therein comprises combusting a fuel/air mixture in a combustor downstream of the exit plane of a fuel nozzle assembly such that such recirculation zones generated by the fuel nozzle assembly are in spaced relation to the exit plane and the combustion products are isolated from the fuel and air in the mixing zone at all operating conditions of the engine.

Méthode de réduction des variations de pression dans la chambre de combustion d'un moteur à turbine à gaz, résultant de la combustion d'un mélange d'air et de carburant à l'intérieur de la chambre de combustion, comprenant un mélange air-carburant, dans une chambre de combustion en aval du plan de sortie d'un injecteur de carburant, de sorte que les zones de recirculation générées par l'injecteur de carburant sont à intervalles par rapport au plan de sortie et les produits de la combustion sont isolés de l'air et du carburant dans la zone de mélange, dans toutes les conditions de marche du moteur.
