Breech Blast Emitted from Recoilless Rifles.

摘要

The purpose of this study was to develop simplified empirical equations and graphical solutions whereby estimates can be made of the breech blast pressure and impulse fields around the breech of any recoilless rifle. Two empirical equations were developed by conducting a model analysis, reviewing recoilless rifle firing test data, and supplementing the data base in the literature with test results of our own from a specially designed propellant chamber and variable area nozzle test device. The equations which result can be used with any size propelling charge in any caliber of recoilless rifle. (Author)
