GRA (NTIS NTS) Country of Origin: United States Country of Publication: United States Abstract: This project was charged with the responsibility of conducting tests on static aircraft panels mounted on the ground at various ranges from the blast. Pressure-versus-time data were obtained using interferometer gauges. The gauge proved to be reliable and easy to operate. Its high-frequency response enabled it to record data to the pressure rise at the front of the blast wave which had not been noted previously. These results show, from measurements taken by pressure instruments mounted flush with the ground, that the rise times at the front of the blast waves were on gamma-radiation intensity by the smple expedient of stacking a few layers of lead breic around the gauge mounts.
