Experimental investigation of thrust augmentation of 4000-pound-thrust axial-flow-type turbojet engine by interstage injection of water-alcohol mixtures in compressor

Description: Report presenting an experimental investigation of thrust augmentation of a 4000-pound-thrust axial-flow-type turbojet engine by interstage injection of water-alcohol mixtures into the compressor at sea-level, zero-ram conditions. the number, size, and arrangement of interstage nozzles were varied to produce a satisfactory augmentation system of minimum complication. Results regarding the unaugmented performance with and without interstage-injection nozzles, augmented performance with three-sta… more

Radioactive Isotopes of Bismuth

Description: Five isotopes of bismuth occur in nature. Using particle accelerators providing helium ions up to 40 Mev in energy and deuterons up to 20 Mev in energy, it was possible to produce and identify two artificial radioactive isotopes. With the advent of the 184-inch Berkeley syncho-cyclotron and its hundreds of Mev energies, it was possible to form highly neutron-deficient bismuth isotopes extending more than ten mass units below stable Bi(209).

The System Pentaether-Uranyl Nitrate-Nitric Acid-Water

Description: The system pentaether-uranyl nitrate-nitric acid-water has been studied in the liquid-liquid region, Aqueous solutions containing 0.0M to 8.2M nitric acid and 0.0M to 2.3M uranyl nitrate were equilibrated with pentaether, and the effects of nitric acid concentration, uranyl nitrate concentration and temperature are discussed. Phase diagrams for the system are presented and approximate delta-H values are given.

Preliminary report on human excretion of tritium

Description: Six subjects received a few millicuries Of tritium by inhalation of isotopically labeled hydrogen gas. The concentration of H{sup 3} in the urine of these individuals has been followed for a period of some 15 days. The rate of excretion of the tritium was found to be constant for a given subject but to vary considerably, among individuals. Data on five individuals arbitrarily normalized to coincide at zero time showed a range in biological half-life from about 9 days to nearly 13 days. These va… more
