For the development of Pulse Detonation Engine (PDE), effects of injected volume and distribution of purge-air gas on multiple-cycle operations of PDE were investigated. In order to improve the uniformity of a mixture, the experimental PDE had four sets of fuel and oxidizer injector in the opposite side at same axial location. In addition, an injector for the air purging was added on the thrust wall so that the direction of purging flow was discussed. In single cycle experiments, the air purging did not affect the pressure and propagation velocity of detonation wave, hence it is only effective for exhausting the burned gas. The amount of injected purging gas was varied in multiple-cycle experiments to find the optimum amount of purging for stable detonations. The results showed that the amount of air purging increased as the cycle frequency increased and the axial injection rather than the radial was effective to exhaust the burned gas.
