【Abstract】 A new device and a corresponding testing system are designed to simulate the status of combustion and mechanics of propellant charge in chamber. The gunpowder gas pressure in different radial positions are obtained by using the ’ detecting stick ’. The different radial pressure testing problem in the same chamber section is solved. The flame spreading process in chamber is obtained by using the ray fibre. The mechanics status near the projectile base before the propellant being ignited is obtained by using a projectile base sensor. Simulation experiments are accomplished and the status of combustion and mechanics of charge bed in chamber is obtained. This new device provides a new method for the study on the simulation of the status of combustion and mechanics of propellant charge in chamber and the launch safety of propellant charge.更多还原
