RF Signatures of Hypervelocity Impacts on Spacecraft
We investigate the radio frequency (RF) signature resulting from a hypervelocity impact on a spacecraft. While hypervelocity impactors, consisting of meteoroids, dust and orbital debris, are known to cause mechanical damage to satellites, very little is understood about the electrical effects associated with an impact. We present a theory to describe the behavior of the plasma produced from a h...
متن کاملSimulation of Hypervelocity Impact Effects on Reinforced Carbon-carbon
Spacecraft operating in low earth orbit face a significant orbital debris impact hazard. Of particular concern, in the case of the Space Shuttle, are impacts on critical components of the thermal protection system. Recent research has formulated a new material model of reinforced carbon-carbon, for use in the analysis of hypervelocity impact effects on the Space Shuttle wing leading edge. The m...
متن کاملCharacterizing Hypervelocity Impact (HVI)-Induced Pitting Damage Using Active Guided Ultrasonic Waves: From Linear to Nonlinear
Hypervelocity impact (HVI), ubiquitous in low Earth orbit with an impacting velocity in excess of 1 km/s, poses an immense threat to the safety of orbiting spacecraft. Upon penetration of the outer shielding layer of a typical two-layer shielding system, the shattered projectile, together with the jetted materials of the outer shielding material, subsequently impinge the inner shielding layer, ...
متن کاملElectromagnetic interference from plasmas generated in meteoroids impacts
– It is shown that the plasma, generated during an impact of a meteoroid with an artificial satellite, can produce electromagnetic radiation below the microwave frequency range. This interference is shown to exceed local noise sources and might disturb regular satellite operations. Introduction. – At the end of 1998, the first modules of the International Space Station will be put in orbit arou...
متن کاملDetection and Analysis of RF Data from Hypervelocity Impacts
Ground based tests were performed at the Max-Planck-Institute für Kernphysik Van de Graaff accelerator in Heidelberg, Germany to explore radiofrequency (RF) emission associated with hypervelocity particle impact induced plasma. Meteoroids and dust traveling between 11 and 72.8 km/s are constantly bombarding spacecraft while on orbit. These hypervelocity particles may cause electrical anomalies ...
