Abstract : Data are presented on calculated minimum pressure for initiation of detonation in a double-base propellant. Good agreement with experiment is found, but the meaning of the agreement is uncertain because of uncertainty in the equation of state data used. The dependence of wave trajectories and reaction zone profiles upon a grain surface ignition versus a point ignition model is investigated. Evidence indicates that point ignition gives theoretical behavior more closely paralleling experimental behavior. Two dimensional calculations are presented showing the energy deposition resulting from passage of a shock over a bubble in a solid charge. Deposition is larger in the region of the bubble than elsewhere. The problem has not been carried to completion because it was found that a rather long running time would be required. Preliminary data on the experimental investigation of equation of state on polyurethane is presented. (Author)
