Dynamic Tests of a 10-Deg Cone Having Three Angular Degrees of Freedom at Mach 8

Abstract

Dynamic stability data were obtained on a slightly blunted 10-deg half-angle cone at Mach number 8. The tests were conducted using a unique balance system which allowed the model to have three angular degrees of freedom. Both a symmetrical model and a model having compound configurational asymmetries were tested at free-stream Reynolds numbers, based on model length, of from 1, 610,000 to 2,950,000. Data obtained on the symmetrical model at roll rated up to 300 rev/min showed the damping-in-pitch derivatives to be nearly constant with roll rate.
