Development and Aerodynamics of Proboscioid Ablating Nose Tips.

Abstract

Rationalization of slender concave shapes on ablating nose tips is obtained in terms of composite laminar/turbulent self-preserving solutions to the nose recession problem. The occurrence of subcritical and critical (violently oscillatory) flow conditions is discussed and associated with specific geometrical characteristics of the ablating nose shape. The presence of distinct oscillaotry modes is noted for both the subcritical and critical cases, and the distinct underlying inviscid instability mechanisms are pointed out. On that basis numerical flow analyses by extension of available unsteady inviscid flow models is suggested, and the nature of the required extensions is outlined. (Author)
