Zero-Lift Drag of Several Conical and Blunt Nose Shapes Obtained in Free Flight at Mach Numbers of 0.7 to 1.3 (open access)

Zero-Lift Drag of Several Conical and Blunt Nose Shapes Obtained in Free Flight at Mach Numbers of 0.7 to 1.3

Report presenting the zero-lift drag characteristics of seven nose shapes on a slender body of revolution in free flight between the Mach numbers of 0.7 and 1.3. Some of the nose shapes included a spherical segment, flat face with a sharp shoulder, flat face with a rounded shoulder, 30 degree and 40 degree total-angle cones, and a spherical segment with two different length spikes. Results regarding drag coefficients and performance for the various shapes are provided.

Wind-Tunnel Investigation at High Subsonic Speeds of the Effects of Wing-Mounted External Stores on the Loading and Aerodynamic Characteristics in Pitch of a 45 Degree Sweptback Wing Combined With a Fuselage (open access)

Wind-Tunnel Investigation at High Subsonic Speeds of the Effects of Wing-Mounted External Stores on the Loading and Aerodynamic Characteristics in Pitch of a 45 Degree Sweptback Wing Combined With a Fuselage

Report presenting an investigation of the effect of wing-mounted external stores on the loading and aerodynamic characteristics in pitch of a 45 degree sweptback wing combined with a fuselage. Store arrangements investigated consisted of stores mounted at the wing tips, stores mounted inboard on the wing undersurface at 46-percent semispan, and stores in both the tip and inboard locations.
