Odom. A drag coefficient Kd based on the 155mm shell, HE, M101

Memorandum report No.1167. Ballistic research laboratories. 1958, - 11 p.Firing tables for the 155mm howitzer are being revised to reflect the latest changes in table format and in the process will incorporate the most recent information on performance and drag characteristics of the M107 shell. Drag coefficients, Kd, obtained from transonic range measurements of the M101 shell, identical to the M107 shell except for its wider rotating band, were fitted with a series of polynomials. The fitting expressions and a tabulation of the drag coefficients at small intervals of Mach Number are given in this report.Contents:Introduction.Shell, 155mm, HE, M101 with fuze.Table of the drag coefficient Kd based on the 155mm shell, HE, M101.
