PLASMA ENHANCED RAPIDLY EXPANDED GAS TURBINE ENGINE TRANSITION DUCT

A plasma enhanced rapidly expanded duct system (11) includes a gas turbine engine inter-turbine transition duct (114) having radially spaced apart conical inner and outer duct walls (60 and 62) extending axially between a duct inlet (64) and a duct outlet (66). A conical plasma generator (2) produce...

Zusammenfassung:	A plasma enhanced rapidly expanded duct system (11) includes a gas turbine engine inter-turbine transition duct (114) having radially spaced apart conical inner and outer duct walls (60 and 62) extending axially between a duct inlet (64) and a duct outlet (66). A conical plasma generator (2) produces a conical plasma (90) along the outer duct wall (62). An exemplary embodiment of the conical plasma generator (2) is mounted to the outer duct wall (62) and including radially inner and outer electrodes (3, 4) separated by a dielectric material (5). The dielectric material (5) is disposed within a conical groove (6) in a radially inwardly facing surface (7) of the outer duct wall (62). An AC power supply (100) is connected to the electrodes to supply a high voltage AC potential to the electrodes.
