Removal of the reflected pressure pulses from the end of a shock tube (U) / by W.A. Jones and F.L. McCallum.

D-16-01-27, D-95-11-68". Digitized edition from print [produced by Defence Research and Development Canada]. Includes bibliographical references. Summarizes the data obtained during the development of a reflection eliminator to prevent positive or negative pressure pulses, generated by shock wave interaction with the end of a shock tube, propagating back up the expansion chamber. The study was shown that both the reflected positive and negative pressure pulses can be reduced to a very small amplitude by a flat plate placed at a predetermined distance downstream of the open end of the expansion chamber, or by a screen with adjustable openings attached to the open end of the expansion chamber.
