THE EFFECTS OF MASS-TRANSFER ON THE DYNAMIC STABILITY OF SLENDER CONES.

Abstract

An exploratory analytical and experimental investigation of the effects of the mass-transfer of an ablating engineering material on the dynamic stability of teflon models slender vehicles in hypersonic flow was initiated. These data obtained with the ablation of engineering materials were compared to data obtained with blowing techniques and very low temperature sublimers. In this comparison of dynamic stability data with masstransfer, no consistency is discernible among the data obtained with the different methods of mass addition. An attempt to generate empirical values for the boundary layer terms in the theory indicates that present theoretical analyses of the stability of slender vehicles including viscous effects have not yet been perfected.
