1025 Investigation of Debris Cloud Generated by Oblique Impact
Details
We have measured debris cloud generated by oblique impact. And in order to evaluate effect of oblique impact of aluminum spheres against a thin laminated target, hypervelocity impact test have been conducted. Impact velocity was approximately 2km/s. Impact angle was 0[deg] and 30[deg]. The experiments were performed to take images of the generated debris clouds behind target using three flash x-rays and to capture them softly using a stack of polystyrene sheets. And then, the images were analyzed to measure the velocity of each fragment. And the mass of recovered fragments were measured. As a result, it is found that at the impact obliquity of 30[deg], heavier and faster fragments were generated with a spray angle ranging from 20[deg] to 30[deg].
