CALIBRATION OF A MICROMETEOROID IMPACT GAUGE.
Abstract
The response of a piezoelectric micrometeoroid impact gauge to both elastic and inelastic impacts was studied. The output from the gauge was found to vary linearly with momentum transfer for both elastic and inelastic impacts. However, for the same direct momentum transfer, the inelastic impacts yielded a substantially larger output. Some theoretical background is provided to show the complexity of the response mechanism of a piezoelectric micrometeoroid impact gauge. A brief study was also made of the craters produced by the glass beads accelerated in the shock tube and impacting on aluminum, brass and steel targets. The data agree with current theory that the penetration varies as the velocity to the two-thirds power. A general review of current micrometeoroid research is also included in this note. (Author)
