| Outline of Final Research Achievements |
The objective of the present study was the upgrading of the pulse-detonation (PD) technology by the liquid-purge method and the laser ignition. The liquid-purge method, which upgrades the PD technology, has become mature to a certain degree. Through the present study, we established the procedure to determine the operation parameters of the liquid-purge method for various operation conditions of the PD combustor, and we became able to operate the PD combustor by the liquid-purge method at various conditions. The laser ignition, which also upgrades the PD technology, is still immature. Therefore, we investigated the characteristics of laser ignition by comparing them with those of conventional spark-plug ignition in simple experimental devices, where the combustible gas mixtures were initially quiescent or flowed at high speed up to 100 m/s.
