Simulation of Nuclear Underwater Shock Waves Using Planar Sources: An Investigation of Feasibility.
Abstract
Various high explosive and/or propellant sources were assessed for use in the Shock Block nuclear simulation development program. The purpose of this program is to design and engineer a planar source that can develop a fast risetime (approximately 0.1 millisecond), long pulse width (approximately 5 milliseconds) pressure pulse at a constant amplitude of approximately 20 MPa (3000 psi) in water. Assessment techniques included: (1) a survey of the properties of fast-burning propellants; (2) one- and two-dimensional finite-difference calculations of candidate charge designs in a water environment; and (3) small-scale experiments investigating the feasibility of developing an HE/propellant charge. Recommendations are made concerning the design of future charges to be tested in the continuing program. These designs rely on: (1) decoupling the high explosive source from the water by means of an air gap; (2) forcing the explosive gases to push a steel plate; and (3) sealing the charge edges as means to ensure a more constant pressure source for the simulation technique. The computed results are made credible by their close agreement with data from a previous Shock Block test. (Author)
