Abstract : An experimental investigation of the combustion processes occurring in the UTIA implosion driven hypervelocity launcher combustion chamber has been conducted in stoichiometric mixtures of hydrogen-oxygen diluted with an excess of hydrogen or helium. The mixtures were ignited using a spark gap or an exploding wire at the geometric center of the hemispherical vessel and piezopressure gauge histories were recorded for various dilutions and initial pressures ranging from 75 to 1000 psi. Heat transfer and ionization gauges were used to measure average combustion wave speeds and to investigate the wave symmetry. Calculations of the final conditions after complete combustion (constant volume combustion assuming no dissipative effects) have been done taking dissociations into account. The derived pressures have been compared with those obtained experimentally. (Author)
