Use of a Foam Hest to Simulate Low-Yield Nuclear Overpressures.
Abstract
A series of nine Foam HEST experiments was conducted. These tests were used to produce simulated nuclear overpressure environments in a research program to investigate the vulnerability of shallow-buried structures (SBS). The tests utilized charge densities varying from 6.9 kg/cu. m (0.43 lb/cu. ft.) to 58.6 kg/cu. m (3.6 lb/cu. ft.), producing overpressures from a low of approximately 5.5 MPa (800 psi) to a maximum of approximately 117 MPa (17,000 psi). Weapon simulation was determined by comparing the measured airblast data records with theoretical airblast records and choosing the best fit in a least square sense. Weapons simulated varied from 0.04 TJ (0.01 kt) to approximately 33 TJ (8 kt). These tests were conducted on structural elements with 0.61-m (2-ft) and 1.2-m (4-ft) clear spans. Assuming a 4.9-m (16-ft) clear span in the prototype structure, the simulated weapons varied from 21.5 TJ (5.1 kt) to approximately 966 TJ (230 kt) on a prototype structure. (Author)
