Comparison of experimental and theoretical normal-force distributions (including Reynolds number effects) on an ogive-cylinder body at Mach number 1.98 (open access)

Comparison of experimental and theoretical normal-force distributions (including Reynolds number effects) on an ogive-cylinder body at Mach number 1.98

Report presenting normal-force and pressure distributions for a body of revolution consisting of a fineness-ratio-3, circular-arc, ogival nose tangent to a cylindrical afterbody 7 diameters long. Comparisons of theoretical and experimental distributions indicate that available theoretical methods are only accurate for angles of attack up to about 5 degrees.

A Comparison of Flight Measurements With Calculations of the Horizontal-Tail Root Bending Moments for a Jet-Powered Bomber Airplane (open access)

A Comparison of Flight Measurements With Calculations of the Horizontal-Tail Root Bending Moments for a Jet-Powered Bomber Airplane

Memorandum presenting a comparison made between the incremental aerodynamic root bending moments on the horizontal tail of a jet-powered bomber airplane measured during a flight investigation over a range of Mach numbers and the bending moments calculated by using available theoretical models in conjunction with measured loads, elevator positions, and elevator and stabilizer twists. Results regarding abrupt maneuvers, gradual turn maneuvers, and effects of downwash are provided.

Effect of a wing leading-edge flap and chord-extension on the high subsonic control characteristics of a spoiler-slot-deflector control located at two spanwise positions (open access)

Effect of a wing leading-edge flap and chord-extension on the high subsonic control characteristics of a spoiler-slot-deflector control located at two spanwise positions

Report presenting an investigation in the high-speed 7- by 10-foot tunnel to determine the effects of a wing leading-edge modification on the effectiveness of a spoiler-slot-deflector control. The modification consisted of a chord extension over the outboard 35 percent of the semispan in combination with a full-span leading-edge flap deflected 6 degrees.
