| Abstract: | Derives the solution of the Lagrange problem for the RLPG with variable cross-section barrel and obtains the conversion relationships among the breech pressure, projectile-base pressure and the average pressure. The results obtained are of general significance. It is proved that the uniform density hypothesis is the sufficiency condition for the proportional expansion hypothesis under the existence of the breech boundary motion and the mass jet. |
