Results of close-in effects of enhanced blast weapons, numerical simulation of blast and response of field structures
conference paper
The Netherlands research program on `Protection of field structures against the effects of enhanced blast weapons (EBWs)' is strongly related to the Canadian Technology Program on 'Force protection against enhanced biast'. The Netherlands program is divided into four research topics (i) Threat/scenario analysis of EBW (ii) Measurement techniques (iii) Development of prediction models: explosion effects, blast propagation and response of field structures, ammo- and POL-storage (iv) Development of a consequence/risk-analysis tool.
This paper presents the development of prediction models for EBW blast and discusses the vulnerability of protective field structures against EBWs threat. Particular in harsh explosion environments the pressure measurements in the fire balt of a thermobaric (TBX) or a fuel air explosion (FAE) are a real challenge. These signals are necessary to develop and validate blast prediction models of EBW explosion effects. Numerical study of the physical effects has led to the implementation of TBX and FAE models into TNO's Blast3D code. The simulation results of the blast propagation show good correspondence to the measured pressures during the Elk Velvet trials at DRDC Suffield, Canada.
