Free-flight heat-transfer measurements on two 20 degree-cone-cylinders at Mach numbers from 1.3 to 4.9
Report presenting heat-transfer data obtained in free flight at supersonic Mach numbers up to 4.90 and local Reynolds numbers per foot up to 27.7 million. Two 20 degree-included-angle cone-cylinder models were launched from a carrier airplane at 36,000 feet of altitude. Results regarding primary data and heat-transfer results are provided.

Effectiveness of a turbojet tubular combustor in screening the turbine from foreign objects
Report presenting the effectiveness of a tubular combustor in screening the turbine from foreign objects measured with air flow corresponding to that at static sea-level rated operation. On average, the effectiveness of the production combustor was only 36 percent for the foreign objects introduced in the tests; that is, 64 percent of the objects penetrated the combustor. Results for six different configurations are provided.

Effect of Temperature on Viscosity of Slurries of Boron and Magnesium in JP-5 Fuel
Memorandum presenting the viscosities of slurries containing 50 to 65 percent by weight of boron in JP-5 fuel at temperatures from 30 to 80 degrees Celsius and of slurries containing 50 percent by weight of magnesium in JP-5 fuel from -40 to 80 degrees Celsius. Plastic viscosities of the boron slurries decreased consistently with an increase in temperature. Results regarding boron slurries and magnesium slurries are provided.

Investigation at high subsonic speeds of the effects of various underwing external-store arrangements on the aerodynamic characteristics of a 1/16-scale model of the Douglas D-558-II Research Airplane
Report presenting an investigation at high subsonic speeds of various arrangements of underwing external stores on a model of the Douglas D-558-II research airplane. Three sizes of a short-cylinder shape and two sizes of a long-cylinder shape were investigated with three thicknesses of pylon support on one store configuration. Results regarding drag characteristics and lift and pitch characteristics are provided.
