Large-scale flight measurements of zero-lift drag at Mach numbers form 0.86 to 1.5 of a wing-body combination having a 60 degree triangular wing with NACA 65A003 sections
Report presenting flight testing at high-subsonic and supersonic speeds at high Reynolds numbers to determine the zero-lift drag of a fin-stabilized body and a wing-body combination. The body was parabolic in profile, had a fineness ratio of 10, and a ratio of body frontal area to wing area to 0.306.

Low-Speed Investigation of Deflectable Wing-Tip Elevators on a Low-Aspect-Ratio Untapered 45 Degree Sweptback Semispan Wing With and Without an End Plate
Report presenting an investigation to determine the longitudinal control characteristics of deflectable wing-tip elevators on a low-aspect-ratio, untapered, 45 degree sweptback semispan wing. The elevators had triangular and parallelogrammic plan forms and flat-plate profiles. Results include the elevator effectiveness and comparison of the elevator effectiveness of deflectable wing-tip controls and trailing-edge flap-type controls.

Analytical evaluation of effect of inlet-air temperature and combustion pressure on combustion performance of boron slurries and blends of pentaborane in octene-1
From Summary: "The effects of variation in inlet-air temperature, combustion pressure, and boron or pentaborane concentration on combustion performance were discussed. It was shown how the theoretical data herein could be employed in obtaining the combustion efficiency of experimental combustors. Data were presented by which combustion efficiencies obtained with a water-quench heat balance could be adjusted for the heat of dissociation of the combustion products."

Experimental Evaluation of Boron-Hydrocarbon Slurry in a 16-Inch Ram-Jet Combustor
"The combustion efficiency of a 50-percent-boron-hydrocarbon slurry was evaluated in a 16-inch ram-jet burner. A peak slurry combustion efficiency of 75 percent was usually obtained, and a value of 84 percent was once measured. The connected-pipe burner was run at a simulated flight condition of Mach number 2.85 at an altitude of 68,000 feet, with a 70-percent diffuser recovery giving a burner-inlet pressure of 1 atmosphere and temperature of 570 degree Fahrenheit" (p. 1).

Panel-flutter investigation at supersonic speeds of a pressurized structure fabricated of 0.020-inch-thick laminated glass-plastic
Report presenting an exploration of the proposition that the structural weight of supersonic missiles should be reduced by the use of pressurized, thin-wall, glass-laminated shells. A model with this type of structure was investigated in the 8- by 6-foot supersonic wind tunnel to determine the minimum internal pressure necessary to prevent panel flutter. Results regarding the empty shell and shell containing liquid are provided.
