Air-Flow and Performance Characteristics of Engine-Stage Supercharger of a Double-Row Radial Aircraft Engine 2: Effect of Design Variables (open access)

Air-Flow and Performance Characteristics of Engine-Stage Supercharger of a Double-Row Radial Aircraft Engine 2: Effect of Design Variables

Report presenting an investigation to determine the effect of the location of the diffuser vanes with respect to the supercharger outlets and the effect of flow conditions at the impeller inlet on the air-flow distribution in the outlets of the engine-stage supercharger of an 18-cylinder double-row radial aircraft engine. The effect of flow conditions at the impeller inlet was investigated by distorting the flow at the inlet and noting the effect in the supercharger outlets. Results regarding the diffuser effect and inlet effect are provided.

Air Flow in the Boundary Layer of an Elliptic Cylinder (open access)

Air Flow in the Boundary Layer of an Elliptic Cylinder

From Introduction: "The present investigation was carried out for the purpose of supplementing the earlier work with information on the boundary layer under such conditions of air speed and turbulence that transition occurs and the layer is partly laminar and partly turbulent. In the work reported in reference 1, the air speed was about 12 feet per second, and it was assumed that the boundary layer remained in the laminar condition until after separation because the separation point remained fixed and the pressure distribution about the cylinder was unaffected until an air speed of 15 feet per second was reached."

Air Flow Investigation for Location of Angle of Attack Head on a JN4h Airplane (open access)

Air Flow Investigation for Location of Angle of Attack Head on a JN4h Airplane

The technical staff of the NACA at Langley Field, has made a series of free flight tests with a JN4h airplane in order to find the best place for an instrument for measuring the angle of attack. A "neutral zone" was found where the air remains either at rest relative to the undisturbed air beyond the influence of the airplane, or is set in motion parallel to the motion of the airplane. This zone is about midway between the two wings and slightly in front of, or at the vertical plane through the leading edges of the wings but the exact position as well as the outlines of the zone varies considerably as the conditions of flight change.

Airborne Radioactivity Surveys for Phosphate in Florida

Introduction: Deposits of phosphate in Florida, located beyond the limits of known producing areas, have been reported by prospectors and mining companies. Much of the information has been based upon prospecting and exploration which was undertaken many years ago and as a result the published data relating to the occurrence of these deposits are fragmentary, and few details relating to specific locations and extent are available.

Abstract: "An airborne radiometric survey of the pre-Cambrian Highlands of New Jersey and New York, and Triassic Newark Basin located in 14 radiometric anomalies in the Highlands. No commercial deposit of uranium discovered. Ground checks revealed that most anomalies were caused by large masses or residual boulders of slightly radioactive granitoid gneiss."

Airborne Reconnaissance Survey of Northwestern Arizona (Arizona Strip) and Southwestern Utah

Abstract: From December 1953 to May 1954 an extensive airborne reconnaissance program was conducted in northwestern Arizona (Arizona Strip) and southwestern Utah. Five surface anomalies were detected, one of which has possible commercial value. All anomalies are within the boundaries of National Park Service jurisdiction, consequently, this report is not for public distribution until clearance is obtained from the National Park Service. A preliminary airborne reconnaissance program was also conducted in the Richfield area. No anomalies were discovered.

Aircraft-Fuel-Tank Design for Liquid Hydrogen

"Some of the considerations involved in the design of aircraft fuel tanks for liquid hydrogen are discussed herein. Several of the physical properties of metals and thermal insulators in the temperature range from ambient to liquid-hydrogen temperatures are assembled. Calculations based on these properties indicate that it is possible to build a large-size liquid-hydrogen fuel tank which (1) will weigh less then 15 percent of the fuel weight, (2) will have a hydrogen vaporization rate less than 30 percent of the cruise fuel-flow rate, and (3) can be held in a stand-by condition and readied for flight in a short time" (p. 1).
