2.4.2 Procedure A 35 mm camera to operate at 24 frames/sec. will be installed in the RB-36. The aircraft will fly at an altitude of approximately 40,000 ft and at a range of from 30 - 60 miles from ground zero. It is éstimated that the light from the burst will provide sufficient light ‘to permit the photographing of the shock wave along the water. if sufficient resolution of the shock propagation can be obtained a peak- pressure vs distance curve my be constructed from the observed veloosty |° ‘the shock wave. éct is scheduled to participate in all shots. 2.5 : + ly > 0 ex: ee i ~ 1.2a Title: ‘ressure vs Tim: \Moderate Pressures) Performing Agency: Sandia Corporation Dr. J.

The pressure-time response of the gages will be transmitted by signal cable to Ampex recorders placed ina concrete shelter. pal 2.5.3 Remarks i This project is scheduled to participate in:(all shots. Limitations imposed by Rad-Safe considerations my restrict the participation to fewer shots.
