摘要： A tunable fluid flow control system (22) for controlling combustion dynamics in a combustor (12) is disclosed. The control system (22) includes a fuel supply path (24) having an inlet portion (26), a first diverted portion (28), a second diverted portion (30), and an exit portion (34). A first diverted portion (28) has a first length and a first diameter. A second diverted portion (30) has a second length and a second diameter and spaced apart from the first diverted portion (28). The first and second diverted portions (28, 30) converge at a merging location (32). The exit portion (34) is coupled to the merging location (32) of the first and second diverted portions (28, 30). At least one flow regulation device (36, 38, 44) is coupled to the inlet portion (26) and configured to divert fuel flow to the first and second diverted portions (28, 30) alternately to generate fuel flow perturbations at the merging location (32).

摘要： An acoustic damper is fixed to a vibration source to extend along an outer surface of the vibration source, forms a passage (R) that takes in air vibration (V) generated by the vibration source, and is provided with an acoustic section (N) having a partition member (5b) closing the downstream side of the passage (R) with respect to the propagation of air vibration (V) to serve as resistance against the air vibration (V), wherein the acoustic section (N) allows air vibration (V) to propagate in the reverse direction, and has partition members (5b, 5c) arranged so as to serve as resistance against the air vibration (V) in respective directions. This makes it possible to prevent generation of stress due to pressure fluctuation caused when reducing vibration, and to achieve a relatively compact configuration.

摘要： A flexible and automatic system and method for blending an inexpensive secondary gas (320) with a primary gas fuel (305) for operation of a Dry Low NOx gas turbine (200). The secondary gas (320) may be a gas fuel such as hydrogen, ethane, butane, propane and liquefied natural gas or an inert gas. Combustion dynamics are avoided by controlling the blended fuel (355) within a permissible range for a Modified Wobbe Index. Combustion dynamics (375) and gas turbine exhaust emissions (370) may also be monitored to maintain safe combustion with the blended fuel (355). A gas turbine control system (290) may adjust the blend (355) and temperature (361) of the primary gas fuel (305) and the secondary gas (320) to promote desired combustion.

摘要： A gas turbine engine augmentor includes an augmentor outer casing (502) and an annular augmentor liner (504) disposed radially within and radially separated from the augmentor outer casing (502) to form a generally annular augmentor liner cooling flow path (500) between the augmentor casing and the annular augmentor liner, and an augmentor flow splitter duct (506) disposed at the upstream end of the augmentor liner and radially between the augmentor outer casing (502) and the annular augmentor liner (504) and defining a splitter flow path (520) between the annular augmentor liner (504) and the annular augmentor flow splitter duct (506). A method of operating a gas turbofan engine including an augmentor includes directing a portion of fan bypass air into a generally annular augmentor liner cooling flow path (500) between an augmentor outer casing (502) and an annular augmentor liner (504), directing a portion of the air in the augmentor liner cooling flow path (500) into a splitter flow path (520) disposed radially outside the augmentor liner (504) and maintaining positive backflow pressure margin between air flow within the splitter flow path and the augmentor liner cooling flow path (500).
