Book Synopsis Aerodynamics of Asymmetric Sabot Discard by : Edward M. Schmidt
Download or read book Aerodynamics of Asymmetric Sabot Discard written by Edward M. Schmidt and published by . This book was released on 1983 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental results are presented which examine the pressure distributions upon projectiles during the portion of the launch cycle which involves strong aerodynamic interference between the flight body and sabot components. Particular attention is given to the simulation of asymmetric sabot discard geometries since these configurations result in transverse loadings upon the projectile. The pressure distribution in a given section of the projectile surface is shown to be strongly influenced only by the flow field associated with the sabot component facing that section. The basic features of the flow are similar in both the symmetric and asymmetric cases. The experiment is compared with existing analytical models and recommendations for improvements are made.
Book Synopsis Wind Tunnel Measurements of Sabot Discard Aerodynamics by : Edward M. Schmidt

Available in PDF, EPUB and Kindle. Book excerpt: This report addresses the flow field around a fin stabilized, hypervelocity projectile during the sabot discard process. The mutual interference of the flows around the flight body and three sabot components is examined through wind tunnel tests conducted at a free stream Mach number of 4.5. Since it was not practical to attempt the actuation of all three sabot components, the flow field was simulated by using splitter plates to develop reflection surfaces along planes of symmetry. The data show the effects of multiple shock interactions, shock-boundary layer interactions, and the variation in aerodynamic loadings as the sabot discard proceeds. (Author).

Download or read book Numerical Simulation of Sabot Discard Aerodynamics written by and published by . This book was released on 1993 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational fluid dynamics (CFD) solutions of the three-dimensional Navier-Stokes equations have been applied to sabot discard aerodynamics for gun- launched, saboted, armor-piercing projectiles. The portion of the launch cycle that involves strong aerodynamic interference between the projectile and discarding sabot (carrier) components has been investigated. Three sabot components were location symmetrically at various positions near the projectile and at angle of attack. The complex system of shock/boundary-layer interactions between multiple bodies (projectile and sabots), during the discard sequence, has been numerically simulated. Computed and measured surface pressures compare favorably for Mach number 4.5 and Reynolds number six million per meter. Comparison of symmetric sabot discard trajectories predicted using CFD and the AVCO sabot design code are shown.

Book Synopsis Computational Ballistics III by : C. A. Brebbia
Download or read book Computational Ballistics III written by C. A. Brebbia and published by WIT Press. This book was released on 2007 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containing the proceedings of the Third International Conference on Computational Ballistics, this book presents new ideas and advanced developments in the field of study of Computational Ballistics. Ballistic studies include applications as varied as the study of the structural and control behavior of rockets and communication satellites; bird strike effects on commercial aircraft, terrorist attacks and automobile crack worthiness modelling. Many basic problems of ballistics are similar to those in other fields of applications, such as combustion, heat conduction, in-flight structural behaviour, trajectory related issues, contact, impact, penetration, structural response to shock waves and many others.A valuable contribution to its field, this text will be of interest to researchers involved in the different areas of computational ballistics and their relationship between computational methods and experiments. Notable topics include: Systems and Technolog; Combustion and Heat Transfer; Propellants; Fluid Dynamics; Fluid Flow and Aerodynamics; In-Flight Structural Behaviour and Material Response; Guidance and Control; Perforation and Penetration Mechanics; Fluid-structure Interaction; Experimental Mechanics/ballistic and Field Testing; High Rate Loads; Composite Material; Shock and Impact.

This book was released on 2022-09-19 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: This multi-disciplinary book presents the most recent advances in exergy, energy, and environmental issues. Volume 2 focuses on fundamentals in the field and covers current problems, future needs, and prospects in the area of energy and environment from researchers worldwide. Based on some selected lectures from the Eleventh International Exergy, Energy and Environmental Symposium (IEEES-11) and complemented by further invited contributions, this comprehensive set of contributions promote the exchange of new ideas and techniques in energy conversion and conservation in order to exchange best practices in "energetic efficiency." Included are fundamental and historical coverage of the green transportation and sustainable mobility sectors, especially regarding the development of sustainable technologies for thermal comforts and green transportation vehicles. Furthermore, contributions on renewable and sustainable energy sources, strategies for energy production, and the carbon-free society constitute an important part of this book.
Book Synopsis The Effect of Muzzle Jet Asymmetry on Projectile Motion by : Edward M. Schmidt
Download or read book The Effect of Muzzle Jet Asymmetry on Projectile Motion written by Edward M. Schmidt and published by . This book was released on 1975 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gas dynamic loadings experienced by a projectile passing through the muzzle gas flow field are investigated by inducing deliberate asymmetries in the muzzle flow. The effect of these asymmetries on projectile yawing motion near first maximum yaw is measured in a ballistics range. The measured data is extrapolated back to the muzzle, and the projectile angular velocity upon penetration of the muzzle blast is evaluated. The projectile linear velocity imparted by the asymmetric gas dynamic loadings is estimated using the hypersonic equivalence principle. The total jump of the projectile trajectory due to both angular and linear velocity is computed and compared with measured values. (Author).
