초록

Under certain conditions, the fuel delivery system can contribute to the formation of strong dynamic pressures in the combustor of a turbine engine. Embodiments of the invention provide a system for dynamically stiffening the fuel supply passage to suppress damaging combustion dynamics. To that end, a Helmholtz resonator can be placed along and in branched relation to the fuel supply passage. The resonator can produce the effect of adding a pressure release opening at a selected location in the fuel line, causing a shift in the fuel line pressure wave pa...

청구항

What is claimed is: 1. An acoustically stiffened fuel supply system for a turbine engine comprising: at least one turbine engine combustion chamber; a fuel supply passage for receiving a pressurized gas fuel therein, the passage having an outlet adapted to discharge fuel into the combustion chamber, the fuel supply passage being defined at least in part by a t-shaped pipe having an open inlet end, an opposing open outlet end and an open branch end disposed therebetween, the t-shaped pipe having an internal passage, wherein the fuel in the passage has an...
