Pagination or Media Count:
Four types of driver sections short driver, baffled driver, single pipe, and multiple pipe driver were designed and tested on a 148th scale model of the BRL 2.44 m shock tube. Pressures were monitored along the test section with piezoelectric transducers to determine waveshape as a function of drivers. Pressure-time waveforms are compared to computer predictions produced by the NASA-Ames one-dimensional hydrocode. Predictions are given for the performance of the BRL 2.44 m shock tube when suitably modified.
