THE EXPLOSIVE RELEASE OF GAS GUN DIAPHRAGMS
NAVAL ORDNANCE LAB WHITE OAK MD
An experimental investigation was conducted to determine the feasibility of using explosive materials to open the diaphragm used for the release of the chamber pressure in a 4-in. gas model launcher. A method was developed, using linear-shaped mild detonating fuse for controlled rupture of the stainless steel diaphragm. The diaphragm is ruptured at a predetermined delay time after the gas propellant has reached a given pressure. The tests show that diaphragms can be ruptured at chamber pressures up to 10,500 psi under the ultimate rupture pressure for the diaphragm.
