Book Description

A combustion driver for a small Hypersonic Shock Tunnel has been designed and tested. Combustion pressure-time histories for stoichiometric hydrogen and oxygen mixtures diluted with varying percentages of helium have been obtained. Tests indicate that the combustion results are repeatable and peak combustion pressure and temperature are controllable within a wide range. The dimensions of combustion drivers appear to have an important effect in that rough burning conditions, reported by other investigators, have not been noticeable except at very low percentage concentrations of helium.
