Consumable Electrode Arc-Melting of Cold-Compacted Thorium Powder

Description: The consumable electrode arc melting of cold-compacted thorium powder has been developed to produce dense, clean, and soft ingots which can be hot rolled without cracking. By using a water-cooled copper crucible, contamination has been prevented and resultant ingots cleaner than the original power have been produced.

Low-Speed Roll Effectiveness of a Differentially Deflected Horizontal-Tail Surface on a 42 Degree Swept-Wing Model

Description: Memorandum presenting an investigation to determine the roll effectiveness of a differentially deflected horizontal tail of a 42 degree swept-wing model. The model was tested through an angle-of-attack range of 0 degrees through the stall in the clean and landing configurations with the horizontal tail in a low position. Results regarding the longitudinal characteristics and lateral characteristics are provided.

Some Effects of Roll Rate on the Longitudinal Stability Characteristics of a Cruciform Missile Configuration as Determined From Flight Test for a Mach Number Range of 1.1 to 1.8

Description: Report discussing testing of a cruciform missile with a low-aspect-ratio wing and flap-type controls to determine the stability and control characteristics while rolling. Longitudinal stability and control effectiveness for this particular configuration were examined. The data obtained was compared to results from a similar model that was rolling significantly less.

Fundamental flame velocity, heat of combustion, and spontaneous ignition temperature of dimethylaminodiborane

Description: The following properties have been determined for a sample of dimethylaminodiborane : (1) maximum fundamental flame velocity for fuel and air at 35 degrees C, 115 +/- 5 centimeters per second ; (2) net (lower) heat of combustion of liquid fuel to gaseous nitrogen, carbon dioxide, and water, and to solid boric oxide, 19,225 +/- 100 Btu per pound ; and (3) spontaneous ignition temperature, 240 degrees +/- 10 degrees F.

Some Effects of Roll Rate on the Longitudinal Stability Characteristics of a Cruciform Missile Configuration as Determined From Flight Test for a Mach Number Range of 1.1. To 1.8

Description: Report presenting flight testing of a model of a cruciform missile configuration with a low-aspect-ratio wing equipped with flap-type controls in order to determine the stability and control characteristics while rolling at about 5 radians per second. Results indicated that if the ratio of roll rate to natural circular frequency in pitch is not greater than about 0.3, the motion following a step disturbance in pitch essentially remains in a plane in space. Results regarding time histories, norm… more

An evaluation of four experimental methods for measuring mean properties of a supersonic turbulent boundary layer

Description: From Summary: "Surveys were made through a turbulent boundary layer on a flat plate by means of a pitot probe, an x-ray densitometer, and hot-wire and cold-wire probes. Results from these surveys were analyzed to determine (a) the reliability of the basic data and hence the methods by which they were obtained, and (b) how well the actual distributions of properties in the boundary layer compare with those commonly assumed in semiempirical and theoretical analyses. All surveys were made at the s… more

Thermal Stability of Pentaborane in the Range 329 to 419 Degrees F

Description: "The thermal stability of pentaborane has been determined in the temperature range 329 degrees to 419 degrees Fahrenheit by measuring the increase with time in the formation of nonvolatile residue. A relationship was established between the thermal stability and the temperature. The expression permitted extrapolation to obtain the stability of pentaborane at either high temperatures and short times or at ambient temperatures and long times" (p. 1).

Free-Flight Flutter Tests in the Transonic and Low Supersonic Speed Range of Three Low-Aspect-Ratio Swept, Tapered Wings on Rocket-Propelled Vehicles

Description: Report presenting flutter data obtained with the use of rocket-propelled vehicles in the transonic and low supersonic speed ranges for three low-aspect-ratio, highly tapered, swept wings. Structural influence coefficients were obtained for each of the three plan forms and calculated mode shapes and frequencies are provided. Time histories for each of the configurations also demonstrate the flutter pattern of each wing.

A Study of Expected Reactor Powers After Project CG-558 as Determined by Slug Rupture Considerations

Description: Studies were conducted to estimate at what powers the B, D, DR, F, and H Reactors will be limited by slug rupture frequencies after completion of project CG-558. Various approaches were used in the calculations. Methods of raising the reactors to the optimum power levels in a manner so as to protect against the possibility of an excessive number of slug ruptures were studied. This report discusses these studies and presents the conclusions drawn.
