Abstract

The disclosure relates to a method of producing charges for cannons with extremely high charge density and favorable burning properties from the standpoints of both wear and pressure vs time characteristics. According to the invention, the charge is formed of mutually parallel, bundled tubular propellant rods which have been provided with specially designed rupture points which cause the charge to be ignited as a pure tubular propellant charge of large length in relation to the diameter of the combustion channels, but finally burns as a pure granular propellant. The disclosure also relates to propellant charges produced according to the disclosed method.
