EFFECTS OF GAS PHASE AND SOLID PHASE DAMPING ON INSTABILITY OF LOW FREQUENCY MODES IN SOLID PROPELLANT ROCKETS,

Abstract

Gas phase and solid phase damping are known to have important effects on the instability patterns in the high frequency (tangential) modes of solid propellant rockets. In particular, intermittency can be associated with damping in the solid phase. The low frequency modes are investigated for several different boundary conditions applied to the solid, with emphasis on these two acoustic loss mechanisms. As a consequence, it is noted that intermittency is not expected to be characteristic of instability in such modes. However, the instability when not continuous throughout burning may be limited to the early portion of the burning time by these mechanisms. (Author)
