A process for recovering vanadium from acid leach liquors by ion exchange using either columns or resin-in-pulp has been developed. The process is economically feasible, and operating techniques were developed which made the process practical from an operating standpoint. The theory, chemistry, and characteristics of the vanadium ion exchange process are fully discussed.

"A method is presented for determining the time-dependent flow over a rectangular wing moving with a supersonic forward speed and undergoing small vertical distortions expressible as polynomials involving spanwise and chordwise distances. The solution for the velocity potential is presented in a form analogous to that for steady supersonic flow having the familiar "reflected area" concept discovered by Evvard. Particular attention is paid to indicial-type motions and results are expressed in terms of generalized indicial forces. Numerical results for Mach numbers equal to 1.1 and 1.2 are given for polynomials of the first and fifth degree in the chordwise and spanwise directions, respectively, on a wing having an aspect ratio of 4" (p. 595).

From Summary: "The results of two investigations, one to determine the relative merits of four experimental and two conventional design 75-millimeter-bore (size 215) cylindrical roller bearings and one to determine the relative merits of nodular iron and bronze as cage materials for this size and type of bearing, are presented in this report. Nine test bearings were operated over a range of dn values (product of bearing bore in mm and shaft speed in r.p.m) from 0.3 x 10(6) to 2.3 x 20(6), radial loads for 7 to 1613 pounds, and oil flows from 2 to 8 pounds per minute with a single-jet circulatory oil feed. Of the six bearings used to evaluate designs, four were experimental types with outer-race-riding cages and inner-race-guided rollers, and two were conventional types, one with outer-race-guided rollers and cage and one with inner-race-guided rollers and cage."

Report discussing the aerodynamic characteristics in pitch and sideslip of a model of a Douglas D-558-II airplane with and without a yaw-damper vane at Mach number 2.01. A revised model was tested using a canopy and modified vertical tail. The revised configuration was found to have higher directional stability, trim lift coefficients, drag, and more positive effective dihedral than the original configuration.

Report discussing an investigation into the performance of several modifications of a side-inlet ramjet engine diffuser. Total-pressure-recovery profiles, Mach number profiles, longitudinal wall static pressure distributions, and variation of the average-static to average-total pressure are presented.

Report presenting an investigation in the high-speed tunnel to determine the pressure distribution at the 20-, 46-, and 65-percent wing semispan stations on a plug-type spoiler and a segment of a semaphore-type spoiler. The investigation was carried out at a range of Mach numbers and angles of attack. The pressure distributions and integrated section force and moment data are presented without discussion.

Memorandum presenting an evaluation of the handling qualities of the Northrop X-4 swept-wing semitailless airplane covering a speed range from stall to a Mach number of 0.92 primarily at 30,000 feet. The characteristic problems of tailless airplanes at low speeds, such as marginal longitudinal stability and control resulting in close center-of-gravity limits, were encountered. Results regarding static longitudinal stability characteristics, dynamic stability characteristics, and static lateral and directional stability and control are provided.

From Introduction: "The present paper contains the results of the investigation of the aerodynamic characteristics at Mach number of 2.01 of the two cruciform wing missiles equipped with larger canard controls and compares the result with that obtained previously with a smaller control."

A proposed new processing technique for the production of uranium tetrafluoride from uranyl nitrate solution is described. This technique involves the application of the fluidized-bod principle for the contacting of gases with powdered solids. A new application of fluidization developed at this Laboratory and applied to the denitration of uranyl nitrate to produce uranium trioxide is also described. The purpose of this work is to develop a low-cost, continuous process for the denitration of uranyl nitrate hexahydrate, the reduction of uranium trioxide to uranium dioxide, and the hydrofluorination of uranium dioxide to uranium tetrafluoride. Uranium trioxide and uranium dioxide powders can be satisfactorily fluidized over a wide range of particle sizes. The product is a powder having a high bulk density and satisfactory physical and chemioal properties. Production rates of 100 Ib/hr/ft/sup 2/ of reactor cross section were demonstrated. Experimental work is continuing to obtain additional information of the effects of operating variables. Experimental work is now underway to determine the optimum hydrofluorination operating oonditions and to estimate the size and number of stages required for the production of specification-grade uranium tetrafluoride.

An electromagnetic instrument similar to the Multitest was built and used to test 2200 uranium slugs. It was found that the equipment could be used to detect inclusions and cracks in the uranium, but that small cracks are not readily detectable on a production basis unless the material is absolutely uniform in inclusion content. The instrument can be used, however, to sort out hidden defects of a reasonable size and to reject grossly dirty uranium.

An investigation to determine the altitude performance of the J57-P-1 turbojet engine and components was conducted at the NACA Lewis altitude wind tunnel. Data were obtained over a corrected inboard rotor speed range from 56 to 106 percent of rated speed, with intercompressor bleeds both open and closed, at altitudes from 15,000 to 50,000 feet and at a flight Mach number of 0.81. The corresponding range of Reynolds number indices was from 0.858 to 0.213. All data presented were obtained with a fixed-area exhaust nozzle sized according to the manufacturer's specification. Over-all engine performance parameters are presented as functions of inboard rotor speed corrected on the basis of engine inlet temperature. Component parameters are presented as functions of their respective corrected rotor speeds. A tabulation of all performance data is included in addition to the graphical presentation. Corrected net thrust is unusually sensitive to changes in corrected inboard rotor speed in the high speed region. A change of 1 percent in speed, at sated speed, produced a change of 6 percent in corrected net thrust . At rated engine speed, increasing the altitude from 15,000 to 50,000 feet at a constant flight Mach number of 0.81 increased the specific fuel …

A turbine blade with a porous stainless-steel shell sintered to a supporting steel strut has been fabricated for tests at the NACA by Federal-Mogul Corporation under contract from the Bureau of Aeronautics, Department of the Navy. The apparent permeability of this blade, on the average, more nearly approaches the values specified by the NAGA than did two strut-supported bronze blades in a previous investigation. Random variations of permeability in the present blade are substantialy greater than those of the bronze blades, but projected improvements in certain phases of the fabrication process are expected to reduce these variations.
