This book was released on 1997 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: Paperback. This publication contains 36 papers taken from three symposia of COSPAR Scientific Commission B, which took place during the Thirty-first COSPAR Scientific Assembly, held in Birmingham, UK, during July 1996. The major areas covered by the symposia and which form this volume are as follows: the particulate space environment, problems in comparative planetology, and laboratory investigations relevant to planetology. Papers on the particulate space environment reflect advances in evaluation of the space environment, the deeper understanding of hypervelocity impact phenomena, and hold interest for the understanding of the natural environment and space debris. Papers on problems in comparative planetology investigate differences in impact melting on the surfaces of different planets, the geology of Alba Petra on Mars and attempts to interpret the geology of that region in terms of the geology of corona structures found on Venus.

This book was released on 2018-07-25 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: All large spacecraft are susceptible to impacts by meteoroids and orbiting space debris. These impacts occur at extremely high speed and can damage flight-critical systems, which can in turn lead to a catastrophic failure of the spacecraft. Therefore, the design of a spacecraft for a long-duration mission must take into account the possibility of such impacts and their effects on the spacecraft structure and on all of its exposed subsystems components. The work performed under the contract consisted of applied research on the effects of meteoroid/space debris impacts on candidate materials, design configurations, and support mechanisms of long term space vehicles. Hypervelocity impact mechanics was used to analyze the damage that occurs when a space vehicle is impacted by a micrometeoroid or a space debris particle. An impact analysis of over 500 test specimens was performed to generate by a hypervelocity impact damage database.

This book was released on 2018-06-11 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 material model has been validated in simulations of published impact experiments and applied to model orbital debris impacts at velocities beyond the range of current experimental methods. The results suggest that momentum scaling may be used to extrapolate the available experimental data base, in order to predict the size of wing leading edge perforations at impact velocities as high as 13 km/s.Park, Young-Keun and Fahrenthold, Eric P.Johnson Space CenterHYPERVELOCITY IMPACT; CARBON-CARBON COMPOSITES; LEADING EDGES; SPACE SHUTTLES; SPACE DEBRIS; THERMAL PROTECTION; THREE DIMENSIONAL MODELS; FINITE ELEMENT METHOD

Download or read book Hypervelocity Impact Analysis by the Method of Characteristics written by Richard Madden and published by . This book was released on 1969 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer method has been developed for the analysis of the initial hydrodynamic phase of hypervelocity impact. The method is based on solving the inviscid, non heat-conducting, unsteady fluid dynamic equations in cylindrical coordinates by utilizing an approach based on the method of characteristics. The method has been used to generate an operational computer program applicable to the impact of an infinitely long right circular cylinder striking a semi-infinite target of the same material. The projectile is assumed to be traveling parallel to its axis of symmetry, and the target is initially at rest. Results are presented for the pressure and velocity fields at various times following the impact. The pressure fields are compared with the pressure fields calculated from an existing hydrodynamic analysis.

Download or read book Hyper Velocity Impacts on Rubble Pile Asteroids written by Jakob Deller and published by Springer. This book was released on 2016-12-01 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis presents a tool to create rubble pile asteroid simulants for use in numerical impact experiments, and provides evidence that the asteroid disruption threshold and the resultant fragment size distribution are sensitive to the distribution of internal voids. This thesis represents an important step towards a deeper understanding of fragmentation processes in the asteroid belt, and provides a tool to infer the interior structure of rubble pile asteroids. Most small asteroids are 'rubble piles' – re-accumulated fragments of debris from earlier disruptive collisions. The study of fragmentation processes for rubble pile asteroids plays an essential part in understanding their collisional evolution. An important unanswered question is “what is the distribution of void space inside rubble pile asteroids?” As a result from this thesis, numerical impact experiments can now be used to link surface features to the internal structure and therefore help to answer this question. Applying this model to asteroid Šteins, which was imaged from close range by the Rosetta spacecraft, a large hill-like structure is shown to be most likely primordial, while a catena of pits can be interpreted as evidence for the existence of fracturing of pre-existing internal voids.
