This book was released on 1968 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Army-Navy Spinner Projectile is a research shape that has been used as the foundation of many spin stabilized weapon designs. The purpose of the wind tunnel tests was to make supersonic wind tunnel Magnus measurements on AN Spinner configurations of 7-, 8-, 9- and 10-caliber lengths. Such an experimental study indicates the effect of length on the Magnus force and moment for a basic spin stabilized shape. (Author).

This book was released on 1970 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A research configuration was formed by attaching wraparound fins in a cruciform arrangement to a 10-caliber Army-Navy spinner projectile. This configuration was tested in a supersonic tunnel to get the Magnus force and moment, as well as the normal force and pitching moment. Model spin rate was generated by means of fin cant.

This book was released on 1972 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The report reviews both theoretical and experimental investigations of the Magnus effect on arbitrary bodies of revolution. The main emphasis is on spinning projectiles at angle of attack, both with and without fins. Flow visualization measurements are used to assess the accuracy of the existing theories. Laminar, turbulent, and mixed boundary layers are considered. (Author).

Download or read book Wrap around fin WAF Pressure Distribution written by John E. Holmes and published by . This book was released on 1973 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal difference between a wrap around fin and a planar fin is that the WAF exhibits an induced rolling moment at zero degree angle of attack, while a straight fin has none. The Naval Ordnance Laboratory, along with other members of The Technical Cooperation Program, initiated a joint investigation into the causes of the induced roll moment. Measurements of the pressure distribution over both the convex and concave sides of a WAF showed that the primary difference in pressure across the fin occurred immediately behind the leading edge with the pressure on the convex side apparently being affected more by the curvature than that on the concave side. In general, for a WAF with fixed curvature, it appeared that the physical characteristic which would have the most effect on changing the roll moment would be the fin cross-sectional profile, especially the leading-edge profile.

This book was released on 1967 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the techniques in current use for measuring dynamic stability derivatives in wind tunnels are described, with emphasis given to the important features of balance system design, data reduction methods, instrumentation and typical balance systems. The use of gas bearings for dynamic stability and roll damping balances is treated and a three-degree-of-freedom balance system employing a spherical gas bearing is described. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The book aims to provide the reader with an updated general presentation of multiscale/multiresolution approaches in turbulent flow simulations. All modern approaches (LES, hybrid RANS/LES, DES, SAS) are discussed and recast in a global comprehensive framework. Both theoretical features and practical implementation details are addressed. Some full scale applications are described, to provide the reader with relevant guidelines to facilitate a future use of these methods.

Download or read book Modern Exterior Ballistics written by Robert L. McCoy and published by Schiffer Military History. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern Exterior Ballistics is a comprehensive text covering the basic free flight dynamics of symmetric projectiles. The book provides a historical perspective of early developments in the 19th century, the technology leading to World War I and that through World War II into the modern post-war era. Historical topics include the first ballistic firing tables, early wind tunnel experiments, the development of free flight spark ranges and the first supercomputer, ENIAC, which was designed to compute artillery trajectories for the U.S. Army Ballistic Research Laboratory. The level of the text requires an undergraduate education in mathematics, physics, and mechanical or aerospace engineering. The basic principles of ballistic science are developed from a comprehensive definition of the aerodynamic forces that control the flight dynamics of symmetric projectiles. The author carefully starts with the basic vacuum point mass trajectory, adds the effects of drag, discusses the action of winds, simple flat fire approximations, Coriolis effects and concludes with the classic modified point mass trajectories. Included in the discussion are analytical methods, change of variables from time to distance, numerical solutions and a chapter on the Siacci Method. The Siacci Method provides a historical perspective for computing flat fire trajectories by simple quadrature and is used in the sporting arms industy. The final six chapters of the book present an extensive physical and mathematical analysis of the motion of symmetric projectiles. The linearized equations of angular and swerving motion are derived in detail. The effects of mass asymmetry, in-bore yaw, cross wind and launch in a slipstream are discussed. Special consideration is given to the derivation and explanation of aerodynamic jump. These subjects are then expanded to include a complete chapter on nonlinear aerodynamic forces and moments. The final chapter in the book presents an overview of experimental methods for measuring the flight dynamics of projectiles. The great forte of Modern Exterior Ballistics is the author's effort to provide many fine specific examples of projectile motion illustrating key flight behaviors. The extensive collection of data on projectiles from small arms to artillery used to substantiate calculations and examples is alone a valuable reference. The ultimate joy of the book is the incomparable comprehensive set of flow field shadow graphs illustrating the entire spectrum of projectile flight from subsonic, through transonic and supersonic. The volume is a necessary addition to any undergraduate or graduate course in flight dynamics.
