What is it about?
This research investigates the feasibility, utility, and limitations of helium-hydrogen-oxygen combustion reactions for hypervelocity impulse facilities applications. It explores how peak pressure, combustion temperature and products develop in pilot-scale combustion tests prior to the development of a new combustion high-enthalpy impulse wind tunnel.

Why is it important?
Deflagration and transition to detonation in helium-hydrogen-oxygen mixtures play a key role in extending the range of high-enthalpy impulse shock tunnel operation. If achieved - it may be used in order to extend the portion of the hypersonic flight corridor that can be conveniently duplicated in laboratory. The knowledge about the mechanisms of energy release in helium-hydrogen-oxygen reactions is essential as deflagration-to-detonation modes in a combustion hypersonic shock tunnel may lead to structural damages and possible failures.
