(Драйздейл B.X. Структурная интеграция при проектировании оперенных бронебойных подкалиберных снарядов).Technical report. – Aberdeen: U.S. Army Ballistic Research Laboratory. 1981, - 54 p.In this report, rational design of long-rod kinetic energy projectiles is considered from the aspect of structural integrity. Primary emphasis is placed on determining the length and configuration of a sabot which is capable of supporting the subprojectile during launch. Strength of materials methods are utilized for the initial design steps; subsequently, finite element techniques are introduced to obtain improved assessments of the total projectile structural integrity. A simplified rule to estimate sabot mass is developed as part of the analysis.Contents:
