Study of Internal Ballistics of Hepta-Tubular Powders

Abstract

In thin paper a solution of the system of equations in Internal Ballistics of a, conventional gun has been discussed for the hepta-tubular powder. The shot-start pressure is taken diffe- rent from zero and the covolume correction also is taken I. into amount and thus some of the results of Tavernierl who has taken zero shot-start preasure and has neglected the . covolume~omtion, have been generalised. It has been. found out that the maximum pressure in the case of hepta-tubular powders always occurs before the all-burnt position.
