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.
