Operation of the AEDC Impulse Tunnel at high stagnation conditions will require diaphragm burst pressures up to approximately 6,900 bars. A hemispherically shaped diaphragm design made of high-strength material has been developed and tested in a test rig for the pressure range from 1,400 to 6,800 bars. Flat diaphragms have been developed and used in the Impulse Tunnel at pressures up to 1,400 bars. A nearly linear relationship between the burst pressure and the ratio of remaining metal thickness to the radius of the cavity into which the diaphragm opens allows linear scaling to different size facilities.
