Book Description
In the survey of high velocity impact information, a great deal of data was accumulated. Considerable difficulty was experienced in extracting original measured quantities, and originating laboratories were contacted whenever possible to supply tabulated data and additional information concerning material properties and measuring techniques. In some cases, such information was no longer available, and information was extracted from graphical data plots, and material properties corresponding to the material specifications were extracted from handbooks. The collected data are organized and presented under separate headings according to the projectiletarget configuration. (Author).

Book Description
HVIS 2005 was a clear success. The Symposium brought together nearly two hundred active researchers and students from thirteen countries around the world. The 84 papers presented at HVIS 2005 constitute an ''update'' on current research and the state-of-the-art of hypervelocity science. Combined with the over 7000 pages of technical papers from the eight previous Symposia, beginning in 1986, all published in the International Journal of Impact Engineering, the papers from HVIS 2005 add to the growing body of knowledge and the progressing state-of-the-art of hypervelocity science. It is encouraging to report that even with the limited funding resources compared to two decades ago, creativity and ingenuity in hypervelocity science are alive and well. There is considerable overlap in different disciplines that allows researchers to leverage. Experimentally, higher velocities are now available in the laboratory and are ideally suited for space applications that can be tied to both civilian (NASA) and DoD military applications. Computationally, there is considerable advancement both in computer and modeling technologies. Higher computing speeds and techniques such as parallel processing allow system level type applications to be addressed directly today, much in contrast to the situation only a few years ago. Needless to say, both experimentally and computationally, the ultimate utility will depend on the curiosity and the probing questions that will be incumbent upon the individual researcher. It is quite satisfying that over two dozen students attended the symposium. Hopefully this is indicative of a good pool of future researchers that will be needed both in the government and civilian industries. It is also gratifying to note that novel thrust areas exploring different and new material phenomenology relevant to hypervelocity impact, but a number of other applications as well, are being pursued. In conclusion, considerable progress is still being made that is beneficial for continuous development of hypervelocity impact technology and applications even with the relatively limited resources that are being directed in this field.

Book Description
High-Velocity Impact Phenomena covers a wide range of pertinent topics dealing with impact phenomena. The book discusses hypervelocity accelerators; stress wave propagation in solids; and the theory of impact. The text also describes the application of the theory of impact on thin targets and shields and correlation with experiment; the numerical evaluation of hypervelocity impact phenomena; and analytical studies of impact-generated shock propagation. The equation of state of solids from shock wave studies; metallurgical observations and energy partitioning; and engineering considerations in hypervelocity impact are also encompassed. Design engineers will find the book invaluable.

Book Description
A statistical analysis of the NASA Space Shuttle Hypervelocity Impact Database to find correlations between meteoroid and orbital debris (M/OD) impacts on the shuttle orbiter fleet and specific mission parameters; Inclination, Altitude, Duration and Year, M/OD impact data, regardless of location, particle type or mission was examined first, followed by the subcategories of Window data, Radiator data, Reinforced Carbon-Carbon (RCC) data, and Flexible Reusable Surface Insulation (FRSI) data, In an effort to characterize and evaluate the meteoroid and orbital debris (M/OD) environment in low earth orbit, post-flight surveys of the shuttle orbiters are conducted to identify damage caused by hypervelocity impacts from M/OD, Survey analysis determines whether the impactor was a naturally occurring meteoroid or man-made orbital debris, as well as the impactor's size and impact velocity, From the post-flight survey data, calculations on the number of impacts from specific particle diameters or specific particle materials are made and compared to mission parameters to help engineers design spacecraft for better mission efficiency by reducing the effects of M/OD impacts This thesis analyzes the NASA Space Shuttle Hypervelocity Impact Database, using regression analysis software, to find correlations between M/OD impacts on the shuttle orbiter fleet and mission parameters to draw conclusions on what is influencing vehicle damage.

Book Description
A high collision velocity was achieved by firing a steel pellet from a small light-gas gun at a target disk fired from a large smoothbore gun. Through the use of a higher velocity target gun and a modified light-gas pellet gun, the impact velocities obtained were higher than those in the Phase I program reported in BRL Technical Note 1337, August 1960 (AD-245 209). The techniques exploit the use of existing equipment to reach these hypervelocities in a range where the need for impact data is urgent. Collisions were predicted with reliability and precision. The experiment demonstrates the feasibility of adding significant target velocities to many hypervelocity launching techniques. The report discusses the techniques, instrumentation and results of the experiment. (Author).
