A study was conducted of the shock initiation of droplets of five fuels in an oxygen atmosphere. The fuels were ethyl nitrate, propyl nitrate, nitromethane, butyl alcohol, and nitrobenzene. Only the two nitrates ignited. They also were observed to ignite in shocked argon. Their behavior is explained on the basis of their weak bonds and their ability to behave as monopropellants. Schlieren photographs showed that autoignition occurred in the wake of the droplet, and that the flame front expanded rapidly and induced a strong blast wave. The trajectories of the flame fronts and blast waves of the burning nitrate droplets were plotted, and empirical expressions were found. Author
