PLASMA ENHANCED RAPIDLY EXPANDED GAS TURBINE ENGINE TRANSITION DUCT

摘要

PROBLEM TO BE SOLVED: To provide a plasma enhanced rapidly expanded gas turbine engine transition duct.

SOLUTION: The plasma enhanced rapidly expanded duct system (11) comprises a gas turbine-to-engine turbine transition duct (114) including conical inner and outer duct walls (60 and 62) disposed through a space in an axially extending radial direction between a duct inlet (64) and a duct outlet (66). A conical plasma generator (2) generates conical plasma (90) along the outer duct wall (62). A typical embodiment of the conical plasma generator (2) comprises radially inside and outside electrodes (3 and 4) mounted to the outer duct wall (62) and separated by a dielectric material (5). The dielectric material (5) is disposed in a conical groove (6) at the radially inward surface (7) of the outer duct wall (62). An AC power source (100) is connected to the electrodes to supply high voltage AC potential to the electrodes.
