This study reports the first experiments of a large-scale hydrogen-fueled oblique detonation engine model conducted in a hypersonic wind tunnel. The stabilization characteristic of oblique detonation wave, the specific combustion mode and the corresponding flow structures are emphasized. Results show that by adjusting the geometry of the combustor in different tests, two stabilized oblique detonation combustion modes relevant to the two theoretical branches of oblique detonation at a given wedge angle, referred to as the strong oblique detonation mode and the weak oblique detonation mode, respectively, are consequently implemented in the combustor.

燃烧室稳定斜爆轰波形成的实验研究

这项研究报告了在高超声速风洞中进行的大型氢燃料斜爆轰发动机模型的首次实验。强调斜爆轰波的稳定特性、特定的燃烧方式和相应的流动结构。结果表明，通过在不同试验中调整燃烧室的几何形状，可以得到与给定楔角斜爆轰的两个理论分支相关的两种稳定的斜爆轰燃烧模式，称为强斜爆轰模式和弱斜爆轰模式，因此，分别在燃烧器中实施。
