摘要：The existing work on the constant pressure guns has been improved upon by introducing the concept of Lagrange mean density function for the propellant gases behind the shot. Lagrange hydrodynamical model has been considered and the expressions have been established to work out the shape factor of the second component of the moderated charge, which will maintain a constant pressure during the burning of this component. This is followed by the numerical computations of a problem to establish the physical interpretation of the results.
