Ion Sensors for Pulsed and Continuous Detonation Combustors

Presented in the article are design and operation principles of ion sensors intended for detecting propagating reaction fronts, deflagration/detonation mode, apparent subsonic/supersonic propagation velocity front, duration heat release by measuring current reactive medium. The electrical circuits without with intermediate amplifiers, short response time high sensitivity, as well very wide dynamic range media highly variable temperature pressure, provided discussed. main advantages their about 1 ms, versatility design, capability monitoring fronts different intensities directly combustion chambers. Several examples sensor applications sensing deflagration-to-detonation transition pulsed detonation engines developed detonations rotating operating on fuel–air fuel–oxygen mixtures presented
