HYPERSONIC STABILITY DERIVATIVES FOR A STANDARD 10 DEGREE CONE

Abstract

The report describes experiments on the stability of an STA standard 10 degree cone. The free oscillation experiments on a sting mounted, open base model used an Optron tracker to register the model's oscillation about zero angle of attack. Values of the static and dynamic pitching moment stability derivatives are given for independent combinations of nine initial oscillation amplitudes (between 1/2 degrees and 5 degrees), five reduced frequencies (omega d/2V between .0025 and .007), two pivot axis locations (x sub cg/l = 55% and 60%), and two nominal Mach numbers (M = 12 and 14).
