Application of Radial-Equilibrium Condition to Axial-Flow Compressor and Turbine Design
Note presenting some of the basic general equations governing the three-dimensional compressible flow of gas through a compressor or a turbine in terms of velocity components, total enthalpy, and entropy. The equations are applied to investigate the maximum compatible number of the radial variations of the gas properties between successive blade rows that a designer is free to specify.

Application of Radial-Equilibrium Condition to Axial-Flow Compressor and Turbine Design
"Basic general equations governing the three-dimensional compressible flow of gas through a compressor or turbine are given in terms of total enthalpy, entropy, and velocity components of the gas. Two methods of solution are obtained for the simplified, steady axially symmetric flow; one involves the use of a number of successive planes normal to the axis of the machine and short distances apart, and the other involves only three stations for a stage in which an appropriate radial-flow path is used. Methods of calculation for the limiting cases of zero and infinite blade aspect ratios and an approximate method of calculation for finite blade aspect ratio are also given" (p. 1).

Burning Washington Coals on Different Types of Domestic Stokers in the Same Hot-Water Boiler: Comparison with Hand and Oil Firing
From Purpose and Scope: "This bulletin presents the results of an investigation of domestic stokers at the Northwest Experiment Station of the Bureau of Mines. Previous publications have dealt with the burning characteristics of Washington coals on a domestic overfeed stoker, a clinker-type domestic underfeed stoker, and an ash-removal-type domestic underfeed stoker designed for burning anthracite. This report includes all the principal results obtained on the three domestic stokers tested and compares these results with those obtained on the same hot-water boiler by hand-firing and oil-firing."

Characteristics of Low-Aspect-Ratio Wings at Supercritical Mach Numbers
"The separation of the flow over wings precipitated by the compression shock that forms as speeds are increased into the supercritical Mach number range has imposed serious difficulties in the improvement of aircraft performance. Three difficulties rise principally as a consequence of the rapid drag rise and the loss of lift that causes serious stability changes when the wing shock-stalls. Favorable relieving effects due to the three-dimensional flow around the tips were obtained and these effects were of such magnitude that it is indicated that low-aspect-ratio wings offer a possible solution of the problems encountered" (p. 1).

Coal Deposits of the Santa Clara District Near Tonichi, Sonora, Mexico
From abstract: The Santa Clara coal district is 7 to 10 kilometers west of Tonichi, a small town on the Rio Yaqui, in southeastern Sonora, Mexico. Tonichi was the terminus of a branch railroad from Corral until May 1945, when the end of the line was removed. The coal deposits were developed by the Southern Pacific Railroad from the 1890's until about 1911, when the mines were abandoned, partly because the coal was found unsuitable for use in locomotives. Other coal deposits, near Los Bronces and San Javier, west of the Santa Clara district, were mined for a number of years to provide coal for a silver smelter at San Javier which was abandoned sometime during the 1920's. Since 1942 the Santa Clara deposits have been reopened; through 1945 about 50,000 tons of coal had been shipped, at first to the Boleo copper smelter at Santa Rosalia, Baja California, and more recently to Guadalajara, Jalisco, for the manufacture of calcium carbide.

Comparison of over-all impact loads obtained during seaplane landing tests with loads predicted by hydrodynamic theory
Report presenting a landing investigation with a flying boat with a conventional configuration to determine the applicability of hydrodynamic impact theory in defining full-scale water impact loads. The results indicated that in addition to chine flare and angular rotation, there are many other factors that may affect overall load, such as elasticity effects, sustained pressures on the area behind the chine, and the effect of variation of wing lift during impact.

Comparison of the structural efficiency of panels having straight-web and curved-web Y-section stiffeners
Report presenting comparisons of the structural efficiency of panels with straight-web and curved-web Y-section stiffeners. In the high-stress region in which failure is at least in part associated with local buckling, panels with curved-web Y-section stiffeners have higher structural efficiencies than panels with straight-web Y-section stiffeners, which is evidenced by higher average stresses at failure, smaller stiffener heights, or wider average spacing of rivet lines.

Constant-Pressure Combustion Charts Including Effects of Diluent Addition
"Charts are presented for the calculation of (a) the final temperatures and the temperature changes involved in constant-pressure combustion processes of air and in products of combustion of air and hydrocarbon fuels, and (b) the quantity of hydrocarbon fuels required in order to attain a specified combustion temperature when water, alcohol, water-alcohol mixtures, liquid ammonia, liquid carbon dioxide, liquid nitrogen, liquid oxygen, or their mixtures are added to air as diluents or refrigerants. The ideal combustion process and combustion with incomplete heat release from the primary fuel and from combustible diluents are considered" (p. 1).

Contributions to the Data on Theoretical Metallurgy: [Part] 10. High-temperature Heat-Content, Heat-Capacity, and Entropy Data for Inorganic Compounds
From Introduction: "This work is both a revision and an elaboration of Bureau of Mines Bulletin 371, which was published in 1934 and included data available to October 1933. This bulletin purposes to collect and correlate all available high-temperature heat-content and specific-heat data for inorganic substances and to formulate tables and algebraic expressions for their representation. It is expected also that this bulletin will have value to those teaching courses in metallurgical and chemical thermodynamics."

The design of low-turbulence wind tunnels
From Summary: "Within the past 10 years there have been placed in operation in the United States four low-turbulence wind tunnels of moderate cross-sectional area and speed, one at the National Bureau of Standards, two at the NACA Langley Laboratory, and one at the NACA Ames Laboratory. This paper reviews briefly the state of knowledge and those features which make possible the attainment of low turbulence in wind tunnels. Specific applications to two wind tunnels are described."

The development of cambered airfoil sections having favorable lift characteristics at supercritical Mach numbers
Several groups of new airfoil sections, designated as the NACA 8-series, are derived analytically to have lift characteristics at supercritical Mach numbers which are favorable in the sense that the abrupt loss of lift, characteristic of the usual airfoil section at Mach numbers above the critical, is avoided. Aerodynamic characteristics determined from two-dimensional wind-tunnel tests at Mach numbers up to approximately 0.9 are presented for each of the derived airfoils. Comparisons are made between the characteristics of these airfoils and the corresponding characteristics of representative NACA 6-series airfoils.
