旋转爆震发动机（RDE）的研究已在许多研究机构开展。RDE具有效率高、结构简单、只需点火一次等优点。对于火箭发动机的实际应用，推力效率的评估和高加速度或多自由度下的燃烧知识是必不可少的。在本研究中，C2H4 + O2混合物作为推进剂。研制了一种滑动式推力测量机构，该机构既降低了噪声，又减少了燃烧气体的排放。因此，获得了推力历史并对推力性能进行了评估。
Study of a Rotating Detonation Engine (RDE) has been carried out in many research institutions. The RDE has the advantage of high efficiency, simple structure and only once ignition. Toward the practical use for rocket engine, the evaluation of thrust efficiency and the knowledge of combustion under high acceleration or multiple degrees of freedom are essential. In this study, C2H4 + O2 mixture was used as propellant. A Slide mechanism for thrust measyrement was developed, and the mechanism reduced noise and exhausted burned gas. So, the thrust history was acquired and the thrust performance was assessed.
