In the present paper we studied detonation initiation processes in the pulse detonation engine system experimentally using piezo-pressure-gauge detonation-Mach-number measurements. Our pulse detonation engine system is a 3.728m-long 50mm-bore tube with a 0.8m^3 vacuum chamber. The igniter is a spark plug for automobile use. We did four kinds of experiments, closed-end initiation with and without Shchelkin spiral, and side-wall initiation with and without Shchelkin spiral. From the experimental results we ensured the Shchelkin spiral effects on the initiation processes, and possibility of open-end initiation which has advantage in gaseous mixing in the system.
