Development of Airblast and Thermal Radiation Instrumentation.
Abstract
This is part of a continuing effort to develop instrumentation for use in underground nuclear tests. In particular, the development of instrumentation to measure airblast and thermal radiation is described. The initial development of an instrumented sphere to measure dynamic pressure in the supersonic flow behind a blast front was completed. Experiments are described that show that it is feasible to use a bar gauge to measure pressure on a surface parallel to the axis of the bar gauge by using a piston and fluid coupling combination. Work is described on sputtering a thin (2 micron) insulating film of sapphire onto the surface of a copper disc. Such films are required in a proposed thermal radiation gauge to measure the total radiation flux in an underground nuclear explosion. Measurements of pressure in the HE driver chamber on the DABS S-2 Test are also described. (Author)
