An experimental explosive chamber has been designed and used for the measurement of the pressure output history of explosives and pyrotechnics in explosive actuators. The design incorporates a variable volume concept, thus enabling the simulation of the pressure-volume history of an actuator as it is used in an actual explosive valve. A pressure transducer measures the dynamic pressure while a Velocity Interferometer System for Any Reflector (VISAR) is used at a sensitivity of 0.021 mm/..mu..sec per fringe to measure the velocity of a moving actuator assembly. The simultaneous pressure and velocity data are used to calculate the pressure-volume equation of state for each explosive and pyrotechnic tested.
