High-Energy, Low-Thrust Jupiter Missions

Description: Previous studies have been made of the relationship among acceleration, specific power, payload fraction, and travel time for many interplanetary missions. These utilized tangential thrust and correspond to the high thrust Hohmann transfer orbits. In addition, a complete optimization of the one way Mars mission has been accomplished. Since the minimum Jupiter round trip time was six and a half years for tangential thrust, calculations were carried out using higher energy transfer orbits. It is … more

ISOTOPIC METHOD FOR AGE DETERMINATION OF INDUSTRIAL PRODUCTS. Quarterly Progress Report, July-September 1959

Description: >The materials and methods used for the long-term nuclide pairs are essentially the same as those previously described. (April - June Report). The split planchet method was used to determine the resolving time of the tracerlab superscalar counting apparatus which is currently in use. A planchet was split in two and a sample of nuclide placed in each half and counted. From these results a formula for calculating true counting rates was evolved. Data on resolving time loss for the Superscalar are… more

METALLURGY INFORMATION MEETING, AMES LABORATORY, IOWA STATE COLLEGE, MAY 2, 3 AND 4, 1956

Description: The elevated-temperature mechanical properties of beryllium were enhanced by forming dispersed-phase alloys. The addition of properly dispersed BeO to beryllium in quantities of 2 to 3% is equivalent to lowering the testing temperature 200 deg at 1000 to 1350 deg F. Similarly dispersed intermetalic compounds such as FeBe/sub 11/ result in a threefold increase in strength at 1350 to 1650 deg F when 1.5 to 3% tron powder is blended with beryllium powder prior to fabrication. Tensile and stress-ru… more

Power Cost Normalization Studies Civilian Power Reactor Program--Sept. 1, 1959

Description: In connection with the development of a comprehensive plan for a ten- year civilian power reactor program, the AEC has had a series of status reports prepared to present a comprehensive review of the technical and economic status of various nuclear power reactor concepts. In as much as the economic data reported by the various contractors reflected different design philosophies, different estimating policies, and in some cases a technology not verified by the AEC definition of current status, S… more

THERMAL STRESS TESTING OF SM-2 FUEL ELEMENTS. Interim Technical Report for January 1, 1959 to January 1, 1960

Description: Thermal stress testing was performed on two fuel plates, one cut from a brazed SM-1 dummy fuel element and the other from a TIG Welded SM-2 reference element. The test specimens were subjected to transverse temperature differences of up to 200 deg F, and distortion and strain at various locations were measured. The effect of the thermal stress was to increase the amplitude of original distortions. Adddtional distortions due to thermal stress were proportional to temperature differential and to … more
