Sažetak
Higher shock speed performance of an arc-driven shock tube has been obtained with the use of a dynamic discharge arc driver (DDAD). In DDAD operation, the driver gas mass is fed continuosly into the arc chamber during the discharge. DDAD operation is shown in increase the power to the arc chamber by raising the arc resistance throughout the entire discharge period. The time-varying arc resistance is calculated by computer program (SPARK) designed to model the electrical discharge performance of the energy storage and driver system. Effects of various design and operating parameters of the arc driver on the overall facility performance are analyzed with the aid of the SPARK program. The DDAD operation uses hydrogen as the driver gas to generate in air shock Mach numbers in excess of 60. Shock speeds of 42 km/sec were obtained in H2/He mixtures.
