Abstract

A plasma jet (PJ) torch igniter with a novel configuration in a scramjet combustor was developed, and ignition tests of the new torch were conducted in supersonic flow. Three kinds of fuels (H2, C2H4, and CH4) at room temperature were tested. Ignition behavior of the N2-N2 PJ depended on the total electric power input to two PJ. With twin PJ, ignition in the supersonic flow was successful for all the combinations of fuels (H2, CH4, and C2H4) and PJ (H2/N2-O2 and N2-N2), even at the lowest electric power input. The superiority of the H2/N2-O2 PJ to the N2-N2 PJ was shown for all fuels, though basic flow structure formed by injection of the twin PJ was the same. This is an abstract of a paper presented at the 30th International Symposium on Combustion (Chicago, IL 7/25-30/2004).
