Parameters of accidental liquid-propellant rocket explosions

Formation of a reactive mixture capable of self-igniting after destruction of partitions between tanks separating liquid fuel (unsymmetrical dimethyl hydrazine) and oxidizer (nitrogen tetroxide) is considered. The mixing mode l suggested in our previous work and based on the theory of Taylor instabil ity of the contact surface is used. The structure and composition of the mi xture formed are studied and the energy (TNT equivalency) is assessed for t he case of liquid-propellant rocket impact on a rigid surface. The results of calculations by this model are compared with available data deduced from large-scale accidents with liquid-propellant rockets and from deliberately designed tests.
