Implication

Experimental evaluation demonstrates enhanced flame area and temperature in a pre-combustion plasma jet igniter, indicating improved ignition efficiency for aerospace systems.

Key Points

The pre-combustion plasma jet igniter produces higher hydroxyl radical concentrations, extended jet lengths, and enlarged flame areas relative to traditional igniter systems.
Increasing the input current from 15 A to 35 A elevated the highest average discharge temperature from 5127 K to 7987 K while expanding the core combustion reaction zone.
Assessment using planar laser-induced fluorescence shows an increased equivalence ratio stabilizes discharge characteristics, highlighting faster and more efficient ignition.
