• Acoustic oscillations
• Numerical simulation
• Pressure filling
• Solid propellant rocket engine

Numerical simulations for different grain models show that the high frequency longitudinal acoustic oscillations could be generated at the moment of pressure filling. The factors affecting the acoustic oscillations have been studied. The results indicate that these factors include the intensity, damping and frequency of the acoustic oscillations. The development and disappearance of the acoustic oscillations are influenced by the nozzle throat size and open-time of the plug.
