WAVES PROPAGATION AND LIQUID ALUMINUM PARTICLE INJECTION IN SOLID ROCKET MOTORS

2013

A method to determine the injection of aluminium particles from the solid propellant burning surface to the core of the chamber in the presence of an acoustic wave field is developed and aluminum-droplet effects on propagation of acoustic waves in the flow of a solid rocket motor are analysed. Changes of the multiphase flow compressibility are calculated by taking into account both the translational and the pulsational motions of the aluminum droplets in consequence of the acoustic waves.

Liquid aluminum particle effects on propagation of waves in solid rocket motor internal flow

2007

Aluminum-droplet effects on propagation of acoustic waves in the internal flow of a solid propellant rocket motor are analysed. Changes of the multiphase flow compressibility are calculated by taking into account both the translational and the pulsational motions of the aluminum droplets in consequence of the acoustic waves. Chemical reactions are not included in the analysis to avoid the complications arising from the non-isothermal and non-chemical-uniform combustion of aluminum in the chamber. Some corrections in current metalized propellant rocket instability calculations accounting for the results of the analysis are proposed.
