SEDAN LONG RANGE BLAST PROPAGATION. Final Report

Technical Report ·
OSTI ID:4667169
Microbarograph records of air-blast waves from the Sedan shot 635 ft below the surface were made at eight stations in California and Nevada at ranges from 100 to 230 miles. A 1.2-ton high-explosion calibration shot was fired at Sedan minus 2 minutes to establish propagation conditions for bursts in air. Comparison of recorded signals indicated that Sedan blast-wave amplitudes averaged 20% of amplitudes which would have been transmitted had the Sedan yield been free-air burst. Individual transmissivity values ranged from 5 to 35%. Variations around the average were probably caused by atmospheric turbulence. Sedan blast waves were ducted toward the west by atmospheric refraction in the ozonosphere where strong summer easterlies were blowing at 100,000- to 200,000- foot altitudes. Rocket wind measurements were made at Tonopah Test Range. Rocket and rawinsonde data were used to calculate atmospheric blast propagations which are in fair agreement with microbarograph measurements. (auth)
