Abstract

Pulse Detonation Engines (PDEs) are being investigated for advanced high-speed propulsion applications due to their potential for high thrust generation, rapid combustion, improved thermal efficiency, and operation at speeds up to approximately Mach 5. This study experimentally investigates multi-cycle PDE operation under non-purged and oxygen pre-flush purged conditions. Thrust-time histories are used to evaluate cycle-to-cycle repeatability for acetylene-oxygen and methane-oxygen cases. The study compares non-purged operation, oxygen pre-flush purged operation, and fuel-dependent thrust response under repeated firing conditions. The results indicate that oxygen pre-flush purging supports more repeatable thrust behaviour during multi-cycle operation, while the acetylene-oxygen case shows higher thrust response than the methane-oxygen case under the common purged operating condition.
