Includes papers presented at a symposium, which represent the state-of-the-art in the development of base bleed projectiles and related research, and are from recognized experts in the field. The papers have undergone a thorough review process.

Base bleed is a technique whereby all or part of the boundary layer is 'bled' from the rear portion of a projectile to the base region. Passage from the model's surface to the base region is by means of concentric cylindrical passageways. The purpose of base bleed is to reduce the Magnus moment on overlong spinning bodies of revolution and to reduce the base drag. Both analytic and experimental results are presented. The boundary layer is represented by means of the momentum thickness.

A theoretical and experimental investigation has been conducted of the pressure distribution on the surface of either a circular cylinder or a truncated cone located within the base region of another circular cylinder at Mach number 2. A similar analysis of pressure distribution was made for rearward-facing two-dimensional steps, and theoretical results were compared with experimental results of earlier investigations. Theoretical base-pressure ratios of two-dimensional steps agreed well with experimental results; however, as a result of the simplifying assumptions made for axisymmetric configurations, only a range of values for theoretical base-pressure ratio could be calculated within which the experimental results were expected to occur. The data generally followed the trends predicted by the theory, and deviations apparently could be explained.

This book presents innovative ideas, cutting-edge findings, and novel techniques, methods, and applications in a broad range of cybersecurity and cyberthreat intelligence areas. As our society becomes smarter, there is a corresponding need to be able to secure our cyberfuture. The approaches and findings described in this book are of interest to businesses and governments seeking to secure our data and underpin infrastructures, as well as to individual users.
