From introduction: Geodata International, Incorporated, conducted an airborne gamma ray and total magnetic field survey which covered a region of North Texas, New Mexico and Oklahoma. The specific area of this report as outlined on Figure 1 was surveyed from an aircraft using large-volume radiation detectors with computer controlled airborne equipment. Each map line was flown in an east-west direction with an average length of 120 miles and each tie line was flown in a north-south direction with an average length of 69 miles. Map lines and tie lines were surveyed spaced at intervals indicated on Figure 2. The data for the total area of Figure 1 were gathered between March-July, 1976.

From objective and plan: The airborne data gathered were reduced using ground-based computer facilities to give the basic uranium, thorium and potassium equivalent gamma radiation intensities, ratios of these intensities, aircraft altitude above the earth's surface, total gamma ray and earth's magnetic field intensity, correlated as a function of geologic units indicated from available geologic maps. Results of analyses of these field data are presented as profile plots of the gamma radiation and earth's magnetic field.

Report describing a series of tests performed to review the safety procedures and systems of Hanford Laboratories' N-Reactor.

Report discussing the longitudinal static and dynamic stability, overall duct performance, drag, and some static and dynamic lateral-stability data obtained from testing of the Chance Vought Regulus II missile. Five different models with various modifications were used in the investigation.

From Introduction: "The objective of this report are (1) to describe the complete fuel system, (2) to discuss the procedure used for transitions between JP-4 fuel and hydrogen, and (3) to present and discuss engine performance obtained with both fuels, and (4) to review the reliability of the fuel system."

Report presenting an investigation of a liquid-hydrogen fuel system developed to operate one of the turbojet engines in a twin-engine light bomber at an altitude of 50,000 feet and Mach number 0.75. The heat exchanger was evaluated in an altitude test chamber in conjunction with the complete aircraft fuel system. Results regarding calculated heat-exchanger performance, experimental heat-exchanger performance, and reliability are provided.

A ram-air heat exchanger was used to vaporize liquid hydrogen. Results regarding calculated heat-exchanger performance, experimental heat-exchanger performance, and reliability are provided.

Memorandum presenting the system analysis, design, and performance of a control system for an experimental flight-type hydrogen fuel system. The fuel system was designed to investigate some of the problems associated with the utilization of hydrogen as an aircraft fuel. Speed control of the engine was obtained by coupling the hydrogen regulator to the JP-4 fuel control.

Report presenting the system analysis, design, and performance of a control system for an experimental flight-type hydrogen fuel system. The system was designed to explore some problems associated using hydrogen as an aircraft fuel. Results regarding the steady-state response, transient response, and performance in engine-speed loop for the system are provided.

Memorandum presenting testing of a twin-engine light bomber modified to utilize hydrogen fuel in one of the two engines during flight at an altitude of 50,000 feet. Three completely successful flights were made using hydrogen fuel. Data are presented to show the effect of tank agitation on fuel pressure and fuel losses.

From Abstract: "The advantage of long operational life, low power drain and miniaturization may be realized in nuclear counting circuits through the use of transistors. The disadvantage of instability, due to the effects of temperature change in the transistor, may be minimized in counting circuit designs. Representative circuits of a binary stage, amplitude discriminator, one shot multivibrator, and ratemeters are included. These were designed using the criteria of an minimum Beta and a maximum Ico."

For greater understanding of possible explosion hazards knowledge is needed of the volume of hydrogen evolved in the calcium and magnesium-nitric acid reactions. Measurements of evolved hydrogen are presented in this project.

Report presenting an experimental study of the compression fields around axially symmetric isentropic spikes with varying degrees of compressive flow turning made at a Mach number of 3.85 to analyze the basic shock structures and thereby establish further design criteria for supersonic-inlet applications.
