The System Zirconium-Iron-Tin. Summary Report No. 5 for July 1, 1957-- June 30, 1958

Description: The zirconium --iron--tin system was investigated up to the first compound in each binary system (ZrFe/sub 2/ and ZrSn) between the temperatures 500 and 1100 deg C. A careful study of the solubility of iron and tin in alphazirconium was also made betwen the temperatures 200 and 800 deg C. The alloys were prepared from ''Grade ''r iodide zirconium (as received and electron bombardment melted) and high purity iron and tin by nonconsumable-electrode are melting techiques under an inert atmosphere.… more

Altitude Performance of the Afterburner on the Iroquois Turbojet Engine. Coord. No. AF-P-6

Description: "The performance and operational characteristics of two afterburner configurations for the Iroquois turbojet engine were evaluated in an altitude test chamber over a range of afterburner equivalence ratios at afterburner-inlet pressures from 733 to 3186 pounds per square foot absolute. These conditions correspond to an altitude range from 38,700 to 66,800 feet at a flight Mach number of 1.5. The only difference between the two afterburner configurations was in the pattern of afterburner fuel in… more

Boundary-Layer-Transition Measurements in Full-Scale Flight

Description: Report presenting tests of the extent of laminar flow that can be obtained with practical wing-surface conditions. Chemical sublimation was used for boundary-layer-flow visualization on the wings of a supersonic fighter airplane in level flight. A method of continuous monitoring using heat temperature resistance gauges was also used on one wing.

Boundary-Layer-Transition Measurements in Full-Scale Flight

Description: Chemical sublimation has been employed for boundary-layer-flow visualization on the wings of a supersonic fighter airplane in level flight at speeds near a Mach number of 2.0. The tests have shown that laminar flow can be obtained over extensive areas of the wing with practical wing-surface conditions. In addition to the flow visualization tests, a method of continuously monitoring the conditions of the boundary layer has been applied to flight testing, using heated temperature resistance gages… more

DEPOSITION OF GAMMA-RAY HEATING IN STRATIFIED LEAD AND WATER SLABS

Description: Typical results are given from a calculation of the deposition of heat in stratified lead and water slabs caused by a monodirectional, monoenergetic beam of gamma rays incident on the slabs. A total of 512 cases were calculated for infinite slabs with finite thicknesses of 1, 2, 4, and 6 mean free paths; source energies of 1, 3, 8, and 10 Mev, and source angles of incidence which were chosen to give slant slab thicknesses of 1, 2, 3, and 4 times the normal thickness. The results were fitted to … more

Evaluation of Three Injectors in a 2400-Pound-Thrust Rocket Engine Using Liquid Oxygen and Liquid Ammonia

Description: Report presenting the performance of three injector types in a 2400-pound-thrust rocket test chamber. Characteristic velocity and specific impulses were obtained over a range of oxidant-to-fuel ratios at a nominal chamber pressure of 600 pounds per square inch absolute. RMI-1 and 2 had fairly similar results, but RMI-3 gave no stabilized data due to combustion instability.

Investigation of a Prototype Iroquois Turbojet Engine in an Altitude Test Chamber Coord. No. AF-P-6

Description: "Operation of the original engine configuration disclosed a severe compressor stall problem at high altitude, which was largely attributed to a radial flow distortion entering the high-pressure compressor. Engine modifications for eliminating or alleviating the stall problem were investigated. These included use of variable high-pressure compressor inlet guide vanes, increased turbine-stator areas, and minor alterations in both the low- and high-pressure compressor rotors" (Abstract).
