Abstract:

The overall design of a shock tube has been validated with an extraordinary level of performance. It has been demonstrated that shock Mach numbers up to M 12 can be predicted to better than or - 2 95 confidence limits and that the purely aerodynamic losses account for about a 1 decrease in the observed shock Mach numbers relative to the ideal performance values. These results set quite a new level of control for large high performance shock tube installations. The mechanical design work with complete reliability is demonstrated after extensive de-bugging the combustion, control and test section. The diaphragm rupture and folding system also functions with complete reliability with respect to diaphragm tearing, etc., but a presently unresolved problem is a material failure which occurs after 15 to 20 shots.
