FOCUSSING OF SUPERSONIC DISTURBANCE GENERATED BY A SLENDER BODY IN A NON-HOMOGENEOUS MEDIUM.
Abstract
The objective of this work is to analyze the flow past a slender body of revolution moving at supersonic velocity in an atmosphere in which the velocity of sound decreases linearly with altitude. The problem is treated in the context of the linearized theory. The primary interest is directed to the pressure distribution occurring in regions where the signal generated by the body is focussed by refraction in the non-homogeneous medium. Expressions are derived for this pressure signature, and it is found that the rise in pressure behind the Mach surface in the variable medium is of the order of four times that occurring behind the Mach cone in a uniform atmosphere.
