Nuclear Blast Attenuation by Ventilation Duct Liners.

reportActive / Technical Report | Accession Number: AD0852783 | Need Help?

Abstract:

Tests were conducted to determine the effectiveness of permeable lining materials in attenuating nuclear blast waves in ventilation ducts. Five sample materials were tested individually and in combination. A special support fixture was built to test the samples. The NCEL compressed-air-driven shock tube was used to generate simulated nuclear blasts with shock pressures up to about 36 psig. Shock attenuations up to 80 were measured. Standard pitot tubes traverse measurements were made to determine ventilation air flow resistances of the sample liners. Author
