Closed vessel technique for assessment of ballistic characteristics in quality control of propellant manufacture

Abstract

"In order to assess the ballistic performance of a propellant it is necessary to measure its following characteristics: (a)Force constant, (b)vivacity, and (c)shape. It is possible to determine (a)and (b)by the closed vessel technique which enables ballistic performance of the propellant in the gun to be estimated. It can be very usefully employed for quality control of propellant manufacture. As more and more experience is gained in the closed vessel technique these tests have several other possible practical applications such as those: (a)for inspection of propellants, (b)for assessment of quality, (c) to reduce proof in guns, and (d)to check ballistics of a lot after long storage."
