Internal Blast Damage Mechanisms Computer Program

Abstract : A computer program has been developed at NOL that describes the shock and blast loading characteristics of the detonation of a high explosive projectile internal to an aircraft structure; both shock wave and confined- explosion gas pressure loads are considered. With certain modifications, the program can be made applicable to any internal explosion irrespective of the type of confining configuration, e.g., a naval ship compartment, land vehicle, or building structure. Discussions are given on the general use and content of the program, the input options available in the code, and the technical aspects of the calculational methods used to determine shock loading functions, confined-explosion gas pressure, venting of the confined gases, and damage propagation to other areas of the aircraft.
