Research on Working Characteristics of Pre-combustion Plasma Igniter

Abstract

Abstract In the future, aircraft will definitely move towards a faster and higher goal, and the scramjet is the only way to go. For scramjet engines, reliable and effective ignition is a key to stable combustion in the combustion chamber. Plasma ignition is the research frontier of ignition-assisted combustion technology. This technology consumes low energy, can significantly reduce the minimum energy required for ignition, and increase the rate of chemical reaction. It has obvious advantages for aero engine combustion chambers. In this paper, the working principle of plasma fuel nozzle based on rotating sliding arc discharge is described, and the discharge characteristics of rotating sliding arc are studied on this basis.
