Available in PDF, EPUB and Kindle. Book excerpt: Several series of tests were conducted to establish the ballistic limit for the various Pegasus and Explorer XXIII detector panels. In these tests extremely small, carefully sized beads were launched in a velocity range that included the perforation threshold. By varying the size, a ballistic limit curve was established on a mass-velocity plot. Such curves were then extrapolated to average meteor velocity to obtain the characteristic mass for each sensor. Additional tests were conducted on the Pegasus panels using the Pegasus test tool, which contains the identical electronic circuitry used by the flight models. These tests included hot and cold tests, thermal cycling after impact, oblique impacts, etc. Several types of anomalous events noted in the operation of the spacecraft could be simulated in this manner. Some indication of the dependence of detection threshold upon size was obtained, and the implications of these tests in the analysis of the results will be discussed.

Download or read book Interplanetary Dust written by Eberhard Grün and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: An excellent handbook on the physics of interplanetary dust, a topic of interest not only to astronomers and space scientists but also to engineers. The following topics are covered in the book: historical perspectives; cometary dust; near-Earth environment; meteoroids and meteors; properties of interplanetary dust, information from collected samples; in situ measurements of cosmic dust; numerical modeling of the Zodiacal Cloud structure; synthesis of observations; instrumentation; physical processes; optical properties of interplanetary dust; orbital evolution of interplanetary dust; circumplanetary dust, observations and simple physics; interstellar dust and circumstellar dust disks. No doubt, the text will be regarded as the standard reference on interplanetary dust for many years to come.

Download or read book Engineering Models In High speed Penetration Mechanics And Their Applications In 2 Volumes written by Gabi Ben-dor and published by World Scientific. This book was released on 2018-12-28 with total page 1116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This two-volume, 1100 pages, 38 chapters book is a significantly expanded, revised and updated version of the monograph by the authors published in 2013 (Ben-Dor, G, Dubinsky, A, Elperin, T, 'High Speed Penetration Dynamics: Engineering Models and Methods,' Singapore: World Scientific Publishing Company). The contents increased by 60%, the number of titles in bibliography doubled and reached 1600; and the scope covers a range of new topics related to hypervelocity penetration, along with high-speed impact.Presented material is structured into two parts. The first part includes description and analysis of practically all known engineering models for calculating high-speed penetration of projectiles into concrete, metals, geological shields, adobe, and gelatine.The second part focuses on the use of approximate models for solving conventional and non-standard problems of penetration mechanics including prediction and optimization of protective properties of monolithic and multi-layered shields against high-speed projectiles and space debris; shape optimization of high-speed projectiles penetrating into various media; modelling of penetration and optimal control of penetrators equipped with jet thrusters; and investigation of the efficiency and optimization of segmented projectiles. The book includes comprehensive overviews on basic classes of problems in high-speed penetration mechanics.This is a indispensable reference guide for scientists, engineers, and students specializing in the field of high-speed and hypervelocity penetration mechanics.
