摘要

A single microparticle launching method is described to simulate the hypervelocity impacts of micrometeoroids and microdebris on space structures at the Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency. A microparticle placed in a sabot with slits is accelerated using a rifled two-stage light-gas gun. The centrifugal force provided by the rifling in the launch tube separates the sabot. The sabot-separation distance and the impact-point deviation are strongly affected by the combination of the sabot diameter and the bore diameter, and by the projectile diameter. Using this method, spherical projectiles of 1.0–0.1 mm diameter were launched at up to 7 km/s. © 2010 American Institute of Physics Article Outline INTRODUCTION SABOT SEPARATION METHOD SINGLE MICROPARTICLE LAUNCHING FACILITY Two-stage light-gas gun at ISAS Sabot design Velocity measurement SINGLE-PARTICLE LAUNCHING TESTS Sabot separation characteristic Projectile trajectory Success rate of single particle launching CONCLUSION
