Abstract:

Acoustic instability in solid propellant rocket motors is a question of the balance of the acoustic gains and losses in the system. With special reference to transverse modes, this question is examined with respect to those loss and gain mechanisms for which some limited information is available. It is interesting that, depending on which mechanisms are predominant, the critical conditions for instability may be quite different functions of the parameters characterizing the rocket. A possible mechanism consistent with the main results of Brownlee and Marble is presented.
