Structural Reaction Program National Sonic Boom Study Project. Summary, Conclusions, and Analysis

摘要

The test area included 21 structures varying in design, construction and age. Furniture, mirrors, television sets and other home appliances, dishes, crystal, bric-a-brac and various other items were in the test structures. The test site was exposed to 1494 sonic booms of overpressures ranging from 1.6 to 23.4 pounds per square foot (p. s. f.). Sonic booms and structural material reaction were measured. To study the cumulative effects of repeated sonic booms, 680 successive flights at a scheduled overpressure of 5.0 p. s. f. were generated during one period of the study. It is concluded that no previously undamaged material was identified during the accumulative effects portion of the study. Sonic boom overpressure levels at which incipient effects appear in structures and materials are presented. (Author)
