Motor Flow Instabilities - Part 2. Intrinsic Linear Stability of the Flow Induced by Wall Injection
Abstract
Thrust oscillations generally occur in large solid propellant motor during a few seconds of the flight, they exactly correspond to the frequencies of the cavity modes. The excitation of cavity modes has been reproduced in small scale solid propellant motors and also in cold gas facilities. However as extensively exposed by F. Vuillot in the present VKI lecture series, there are different possible causes of this excitation and all of them may play a role. Among them, as suggested by F. Vuillot, see 1, there is the intrinsic instability.
