  • A semi-closed pressure-loading vessel was designed to test the dynamic pressure bearing capacity of a laser ignition window.The mathematical model that describes the relationship between the propellant combustion and the pressure in the vessel was built and its validity was verified.The calculated results were fairly consistent with those achieved from tests.Then the vessel was used to test the bearing capacity of a sapphire window sample, the curves showing the pressure variation of the vessel were obtained and compared with those of the gun chamber.The results indicate that the sapphire window sample could satisfy the requirement of the gun's laser ignition.This vessel could simulate the actual dynamic pressure variation of the interior ballistic of the gun, which may provide a valid method for testing the dynamic pressure bearing capacity of the laser ignition window.
