Abstract

A plasma jet igniter is used to reliably relight a jet engine at high altitudes under adverse combustion conditions. The air-fuel mixture from the primary combustion zone of the jet engine combustor may be used as the plasma medium or, alternatively, liquid fuel direct from the aircraft fuel system may be used as a fuel charge.
