Abstract : A high energy shock tube was developed that employs free piston compression to energize the driver gas. The shock tube may be operated in either a constant volume or a constant pressure mode, depending upon whether or not the piston is brought to test prior to diaphragm rupture. The constant volume mode was used to produce shock velocities up to 30,000 feet per second in helium and argon. The constant pressure mode was used to obtain tailored interface operation with helium driving argon at shock Mach numbers around 10. Analyses were developed for predicting piston behavior and shock tube operating characteristics in both modes. The results of these predictions are compared with the measurements.
