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)
