Plasma ignition and assisted combustion technology is the frontier of energy power research field. The research background and significance of plasma ignition and assisted combustion were introduced. The basic principle of plasma ignition and assisted combustion was analyzed. The common type of plasma ignition and assisted combustion are introduced. Then three mechanisms of plasma ignition and assisted combustion are expatiated, which are thermal enhancement, dynamic enhancement and transport enhancement. Moreover, aiming at plasma ignition and assisted combustion using on aero-engine related research at home and abroad, two kinds of new type plasma ignition and assisted combustion solution are put forward. Finally, plasma ignition and assisted combustion application in aero-engine is discussed.
