A Novel Device for Bursting Shock-Tube Diaphragms

Abstract

The new GALCIT 17-in. low-pressure shock tube is equipped with a novel device which was
\ndesigned to overcome some of the difficulties encountered in attempting to precisely select and control the bursting pressure of very thin diaphragms. This device is a cutter, shown in Figs. 1 and 2, which consists of two blades set at right angles in a cruciform configuration and positioned in the tube on the low-pressure side of the diaphragm.
