Abstract
Upgrade proposals are presented for the DRDC Suffield Blast Tube facility designed to extend its testing range and capabilities for conducting studies of structural response and injury from blast. By means of straightforward modifications, the facility’s operational Pressure-Impulse (P-I) envelope can be greatly extended as well as its capacity to test full-scale responding targets. Blast conditions equivalent to those from charges of several kilograms of high-explosive to small tactical nuclear devices (0.25KT) can be simulated. This extended capability can be achieved by the following modifications which can be implemented independently in phases if necessary: - Installation of an optional breech insert for condensed low-explosive (LE) charges; - Installation of a relocatable test table; - Construction of an extension/expansion section for the current end of the Tube; - Refurbishment of the current main 30m Test Station; - Upgrade and refurbishment of the current FAE fuel-flow control and firing system. Advanced conceptual designs for the upgrades are presented, and the efficacy of the proposals in extending the P-I range is demonstrated by blast CFD modeling. For each upgrade proposal, a more detailed engineering study will be required prior to proceeding with fabrication or re-construction; sub-scale shock-tube testing and more detailed computational modelling should be applied for this purpose. The upgraded facility offers much lower cost, higher reproducibility and co
