为了测量高频脉冲爆轰火箭发动机的推进性能，建立了实验装置。利用无阀模式，PDRE在没有吹扫过程的情况下成功地以110 Hz的最大工作频率运行。在本研究中，利用富氧空气代替氧气作为氧化剂，使用液态汽油作为燃料，因为它的汽化会冷却热燃烧产物，从而形成缓冲区，确保稳定运行，而无需吹扫过程。得到了大范围工作频率下的推力，包括满填充和部分填充情况。根据部分填充条件的结果，建立了部分填充效应的经验公式。此外，还进行了分析，得出了一个非常相似的方程。因此，得到了不含吹扫过程的无阀PDRE的部分充注模型。最后，将该模型与传统操作中开发的其他模型进行了比较。
To measure the propulsive performance of a high-frequency PDRE (pulse detonation rocket engine), an experimental facility was established. Utilizing the valveless mode, the PDRE was operated without the purge process at a maximum operating frequency of 110 Hz successfully. In this study, oxygen-enriched air instead of oxygen was utilized as oxidizer and liquid gasoline was used as fuel because its vaporization would cool the hot combustion products, which would create a buffer zone and ensure stable operation without the purge process. The thrust under a wide range of operating frequencies was obtained including over and partially filled cases. Based on the results of partially filled conditions, one empirical formula for the partial fill effect was developed. In addition, analysis was carried out which resulted in a quite similar equation. Therefore, a partial fill model for the valveless PDRE without the purge process was obtained. Finally, comparisons between the proposed model and other models developed in traditional operations were performed.
