A method for assembling a gas turbine engine (10) that includes providing a low-pressure turbine inner rotor (42) configured to rotate in a first direction, providing a low-pressure turbine outer rotor (38) configured to rotate in a second direction that i...

A flow field (38) forming one wall of a channel (36) in a flow field plate of a solid oxide fuel cell, the flow field includes a flat substrate (40) having a patterned array of differently-shaped flow barriers (52, 64, 66) projecting from the substrate int...

A gas turbine engine system having improved thermal efficiency, which comprises: (1) an inlet air stream (66); and (2) a dry low emissions combustor assembly (22) having an air inlet (156) for receiving the inlet air stream, at least one bleed air port and...

A gas turbine engine includes a compressor powered by a turbine (24). The turbine (24) includes a nozzle (34) having vanes (42) extending between outer and inner bands (44,46). Each vane (42) includes an internal cooling plenum (48) and a bypass tube (50) ...

A method and apparatus for predicting and avoiding lean blow-outs (LBOs) in a gas turbine engine; the method includes extracting (116) a plurality of tones in pressure signals (102) representative of pressure within monitored combustor cans, tracking (128)...
