Experiments and Numerical Calculations on an Ignition System

Aim To present a new kind of rapid ignition tube for igniting the propellant of heavy calibre gun uniformly and synchronistically so as to decrease the pressure wave. Methods Firing tests were carried out. Relationships between pressure and time ( p t curves) at different positions of the tube are measured. The mode of igniter tube of quasi one dimensional two phase flow is given. Results\ The test results indicate that the speed of ignition front in the ignition tube is very fast and the pressure distribution within the igniter tube is uniform. Results of experiments and numerical calculations of the combustion in the igniter tube are in reasonable agreement. Conclusion\ The new igniter tubes have a very high velocity of propagation of ignition stimuli and can ignite the propellant bed synchronistically.
