摘要

This paper describes the performance test of a free-piston shock tube built in Department of Aeronautics and Astronautics, Kyushu University and some results of the performance test are shown. This shock tube was built for the purpose of investigating high temperature effect in shock heated gas. In this type of shock tube, the performance of a facility partly depends on the characteristics of a compression tube, so that, the characteristics of the compression tube were calculated and compared with the experiments. The comparison shows good agreement between the experiment and calculation concerning the compression process of the compression tube. It has been confirmed that the facility can produce shock Mach numbers of 11 to 24 for the initial test section pressures of 65.5 Pa to 1.33 kPa in nitrogen and air.
