U.S. Army Materiel Command pamphlet. Research and development of materiel engineering design handbook. Headquarters. U. S. Army Materiel Command, 1963. – 59 р.This pamphlet, one of the series which will comprise the Ordnance Engineering Design Handbook, deals with the subject of Exterior Ballistics, covering Trajectories, Differential Effects and Data for Projectiles. The pamphlet pertains to that phase of projectile life starting at the gun muzzle (or, for a rocket, at burnout) and ending at the point of burst or impact. The subject is covered in a manner intended primarily to assist the ammunition designer in recognizing and dealing with the design parameters of projectile weight, shape, muzzle velocity, yaw, drag and stability, in designing for optimum results in range, time of flight and accuracy. It is hoped that it will also prove helpful to other personnel of the Ordnance Corps and of contractors to the Ordnance Corps. Because of its complexity, it is possible to cover the subject only briefly in this volume, but an attempt has been made to incorporate references which will permit the designer or the student to explore in more detail any phase of the subject.
The ballistics of bombs and of intermediate and long range missiles are not covered in this pamphlet. Neither are the problems associated with Interior Ballistics or of Terminal Ballistics. These subjects will be covered by other pamphlets.Contents:
