Abstract: The Beckman & Whitley Model 189 Framing Camera is used at a framing rate of 1,440,000/sec for this study. An external stereoscopic mirror arrangement places pairs of stereo images on the film plane. The shaped-charge liner is plated and marked with reference rings. It fires through a mirror at 45° into target material, thus providing simultaneous performance data. Since the effective shutter speed is 1/4 μsec and the effective aperture is f/14.5, intense light from an argon-explosive bomb is needed. Photographic materials are pressed to the upper limit to obtain adequate exposures. Sharp definition and minimum background are required to make accurate measurements from enlargements of the images obtained. The photo sequences are well suited for study with a stereo viewer for observation of detailed effects. Precise measurements for velocity profiles are made from cross-section plots reconstructed on a geometrical plotting device. The device projects the film images to a plotting screen; placing cross-hairs on corresponding points locates a point in space with a standard deviation of 0.08 mm. The liner collapse velocity obtained is then used in analyzing the jet formed by the shaped charge.
