Experimental study on the influence of the injection structure on solid scramjet performance
TL;DR: In this paper, the influence of three different injection structures on the performance of a solid scramjet was investigated using direct-connect tests using a boron-based fuel-rich propellant and simulated a flight Mach number 5.6 at 25 km.

Investigation of the effect of chemistry models on the numerical predictions of the supersonic combustion of hydrogen
K. Kumaran,Viswanathan Babu +1 more
TL;DR: In this article, the influence of chemistry models on the predictions of supersonic combustion in a model combustor is investigated, and the results show that multi-step chemistry predicts higher and more wide spread heat release than what is predicted by single step chemistry.

Combustion Tests of a Staged Supersonic Combustor with a Strut
TL;DR: In this paper, a staged supersonic combustor with a strut-front first-stage injection and second-stage wall injectors at its divergent section was introduced to increase the pressure in the divergent sections under the limitation of the peak pressure at its minimum cross-sectional area section.
