The ignition limits of mixtures of muzzle gas and air are measured with a shock tube as part of a study of gun muzzle flash. The muzzle gas is simulated by mixing its components in the proportions of the calculated propellant combustion products. A few changes and additions have been made to the apparatus used in this work. Acquisition of a counter-chronograph has made it possible to simplify the procedure for measuring shock velocity. A spark source and associated delay circuit, previously used in photography of gun firing phenomena, have been repaired and rebuilt in preparation for spark photography of shock tube phenomena.
