ROLL DAMPING MOMENT MEASUREMENTS FOR THE BASIC FINNER AT SUBSONIC AND SUPERSONIC SPEEDS

Abstract : Wind tunnel measurements are presented of the aerodynamic roll damping moment coefficient derivative of the Basic Finner configuration. Data were obtained over the Mach number range from 0.22 to 4.81. At four Mach numbers the roll damping moment coefficient derivatives were measured as a function of angle of attack with roll rate as a parameter. A free decay technique was used to obtain the data. The present results compare favorably with free flight ballistics range data.
