Download or read book Small Caliber Projectile Target Impact Angle Determined From Close Proximity Radiographs written by and published by . This book was released on 2006 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-caliber rounds have a yaw cycle of approximately three meters, but the magnitude and initial yaw varies from shot to shot, even when fired from the same gun. This yaw cycle becomes a variable that researchers must consider when looking at the lethality of an individual shot and round type, especially when testing at close ranges where the yaw cycle is high. Four orthogonal radiograph images provided measured pairs of pitch, yaw and their Z-locations, a curve is fitted through all four pair of points using a fundamental Aerodynamic equation. The fitted curve is then carried out a know distance to the target where the curve provides an expected pitch, yaw, and total angle of attack at impact. Upon completion of a significant number of shots, this method can provide an accurate estimate of measurement error.

Download or read book Yaw Card Influence on Stability and Yaw Growth for Spin Stabilized Projectiles written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using an impulse or Dirac delta approach, the stability and growth of yaw for a spin-stabilized projectile as it transits a yaw card range is investigated. The card-induced changes in the complex yaw arm amplitudes and phases are expressed as difference equations. For a yaw card range with uniform spacings, the solutions to the general difference equations yield the magnitude and phase values for the complex yawing arms as a function of the card index number. A stepwise encounter with a yaw card reduces the epicyclical phase values across the yaw card. The parameters for the solution include encounter phase value at the entrance of the range, the characteristics of the yaw card, and the distance between the cards. Critical curves separating stable and unstable flight are presented as a function of yaw card spacing and a stability parameter that depends upon both the flight characteristics of the projectile and the card material and thickness. Quasi-universal curves of a transformed epicyclical phase encounter value versus a normalized epicyclical phase reduction value are graphically presented.

Available in PDF, EPUB and Kindle. Book excerpt: This report presents an improved method for analysis of the effect of yaw cards on the determination of the pitching moment coefficient of symmetric missiles. Several comparisons of the present method axe made with spark photography range results obtained for the same projectiles, and a proper treatment of yaw-card data is shown to significantly improve the agreement between the two techniques.
Download or read book Lightweight Ballistic Composites written by Ashok Bhatnagar and published by Woodhead Publishing. This book was released on 2006-06-30 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ballistic composites need to be lightweight and durable as well as exhibiting high impact resistance and damage tolerance. This important book reviews these requirements, how the materials used for ballistic composites meet them and their range of applications.After an introductory chapter, Lightweight ballistic composites is split into two main sections. The first part of the book explores material requirements and testing. There are chapters on bullets and bullet fragments, material responses to ballistic impact, standards and specifications, modelling and test methods. Part Two reviews the range of materials used, production methods and applications. Topics discussed include high-performance ballistic fibres and ceramics, non-woven ballistic and prepreg composites, and their uses in body armour, vehicle and aircraft protection.This major book is the first of its kind to give a comprehensive review of the current use of lightweight ballistic composites in both military and law-enforcement applications. It is an invaluable reference for all those involved in personnel and vehicle protection in defence and police forces around the world. - Reviews the current use of lightweight ballistic composites in both military and law-enforcement application - An authoritative overview of the range of materials used, production methods and applications - Explores material requirements and testing
