Abstract : During nuclear weapons tests a series of gages was used to measure the airblast dynamic pressure. Presence of desert dust raised questions about the evaluation of results. Six of these gages were tested. A rough theoretical analysis predicts the performance of most of the gages tested with reasonable accuracy and shows the effect of dust loading and airblast velocity on their calibration. Results indicate that a combination of the measurements from two of the gages tested (Sandia Snob gage and the SRI-Z gage) is likely to lead to the most reliable data. Where results from only a single gage are available, some independent way, such as photographic records, must be used to estimate dust loading before the dust effect can be evaluated. (Author)
