A plasma injection module includes a fuel receiving end, a discharge end opposite the fuel receiving end, and an axial fluid pathway extending between the fuel receiving end and the discharge end. An insulator assembly defines a first portion of the axial fluid pathway proximate to the fuel receiving end. An injection tube assembly having a permanent magnet is positioned downstream of the insulator. A voltage input connection is arranged downstream of the insulator assembly and upstream of the injection tube assembly. The voltage input connection secures a voltage source to the injection tube to form a plasma filament within and adjacent to the axial fluid pathway. During operation a permanent magnet produces a magnetic field that interacts with the 10 plasma filament to rotate the plasma filament and increase an area of ignition between the plasma filament and the combustible material at the discharge end.

PLASMA-ASSISTED MICRO-INJECTOR

A method and apparatus directed at a plasma-assisted micro-injector suitable for turbine engines that allows for the use of different fuels and different fuel mixtures. The plasma-assisted micro-injector generates a non-equilibrium type plasma across the fuel or fuel mixture that improves combustion performance.
