INVESTIGATION OF THE STATIC LONGITUDINAL AERODYNAMIC CHARACTERISTICS OF A 1/10-SCALE MODEL OF THE BLUE SCOUT JR. AT MACH NUMBERS FROM 0.40 TO 1.03

Abstract

Results were obtained in the Langley 8-foot transonic pressure tunnel at Mach numbers from 0.40 to 1.03 for a 1/10-scale model of the Blue Scout Jr. Tests extended over an angle-of-attack range from about -6 to 6 degrees at a Reynolds number per foot of approximately 4.0 x 10 to the 6th power. Results indicated that the complete configuration exhibited nonlinear variations of normal-force and pitching-moment coefficients with angle of attack which were attributed to the downwash field of the forward fins and its effects on the rear fins. The complete configuration was stable about the test center-of-gravity location which was close to the estimated fullscale-vehicle initial center-of-gravity location. (Author)
