Abstract

Wind tunnel roll damping data on the Basic Finner are presented for subsonic speeds up to Mach 3. Rolling moment coefficients were obtained with a 5% accuracy in the transonic regime and to within 3% at supersonic speeds. A drop in roll damping in the transonic region is attributed to the occurrence of a shock wave on the fin causing a drop in fin lift. The measured roll rate coefficient was found to be invariant with the roll rate at all Mach speeds at zero angle of incidence, in contrast to previous tests in which the roll rate constant remained invariant with the rate only in supersonic regimes.
