An Investigation at Transonic Speeds of the Effects of Fences, Drooped Nose, and Vortex Generators on the Aerodynamic Characteristics of a Wing-Fuselage Combination Having a 6-Percent-Thick, 45 Degree Sweptback Wing

Description: Report presenting an investigation at transonic speeds to determine the effects of fences, drooped nose, combination fences and drooped nose, and vortex generators on a 45 degree sweptback wing-fuselage combination. The purpose of undertaking this investigation was due to the pitch-up tendency that results from leading-edge vortex-type flow on thin sweptback wings. The data for each component and their interaction with one another is also provided.

Wind-Tunnel Investigation at Low Speed of the Yawing Stability Derivatives of a 1/9-Scale Powered Model of the Convair XFY-1 Vertically Rising Airplane, TED No. NACA DE 373

Description: "An experimental investigation has been conducted in the Langley stability tunnel at low speed to deter+nine the yawing stability derivatives of a 1/9-scale powered model of the Convair XFY-1 vertically rising airplane.

Comparison of theoretically and experimentally determined effects of oxide coatings supplied by fuel additives on uncooled turbine-blade temperature during transient turbojet-engine operation

Description: From Summary: "An analysis was made to permit the calculation of the effectiveness of oxide coatings in retarding the transient heat flow into turbine blades when the combustion gas temperature of a turbojet engine is suddenly changed. The analysis is checked with experimental data obtained from a turbojet engine whose blades were coated with two different coating materials (silicon dioxide and boric oxide) by adding silicone oil and tributyl borate to the engine fuel. The very thin coatings (a… more

Coring pattern for K Pile

Description: Pile operation data from 100-H and 100-C has demonstrated that symmetrical heat generation (flux distribution) can be attained with enrichment or enrichment and shortened control rods. The previous coring pattern was based on 100-H operation prior to enrichment and therefore was designed to accomodate an asymmetrical flux distribution. Because the present K reactor design includes shortened control rods and operation will probably include enrichment, the coring design has been revised to a symm… more

Effect of axially staged fuel introduction on performance of one-quarter sector of annular turbojet combustor

Description: The design principle of injecting liquid fuel at more than one axial station in an annual turbojet combustor was investigated. Fuel was injected into the combustor as much as 5 inches downstream of the primary fuel injectors. Many fuel-injection configurations were examined and the performance results are presented for 11 configurations that best demonstrate the trends in performance obtained. The performance investigations were made at a constant combustor-inlet pressure of 15 inches of mercur… more

General Flattening and Power Curves

Description: Introduction: "In the evaluation of pile designs it is necessary to know how the production varies with the number of tubes. It has been possible to solve the problem in terms of some general parameters whose values may be quickly computed for any specific design when the pertinent information is available."

The Kinetics of the Circulating-Fuel Nuclear Reactor

Description: Abstract: "In a circulating-fuel reactor, the circulation of the fuel cause a damping of power oscillations of the reactor. This is demonstrated under the assumption, that there is no mechanical vibration coupled with the oscillation of reactor power, and that the shapes of the hydrodynamic flow does not vary with time."

Calculations pertaining to the expansion of oxide conversion facility, Building 224-U. Project CA-513-B

Description: This report discusses the proposal to expand the existing 224-U Building from an instantaneous rate of 13.5 tons of uranium per day to 18.5 tons per day. This is to be accomplished by the installation of two additional 8{prime} calcining kettles (or pots) available through the Atomic Energy Commission from Luckey, Ohio. It is the purpose of this report to present calculations and recommendations upon which design work is proceeding. This expansion is to utilize existing facilities of 224-U when… more

Preliminary investigation of plate-type molybdenum disilicide fuel elements for an air-cycle nuclear reactor

Description: From Summary: "Flat, plate-type elements, 3.5 by 0.5 by 0.070 inches in size and containing 10 percent elemental natural uranium, were produced by hot pressing. The elements were acid-treated to remove surface uranium and then coated with an alumina glaze. Such an element remained stable and did not lose detectable quantities of fission fragments in a 400-hour treatment at 1800 degrees F in a flux of 5 X 10 to the 11th power neutrons per square centimeter per second. Such elements are convenien… more

Some approximate methods for estimating the effects of aeroelastic bending of rocket-propelled model-booster combinations

Description: Report presenting methods for estimating the aeroelastic effects and structural requirements of rocket-propelled model-booster combinations that are nearly symmetrical. The methods differ principally in the manner in which booster stiffness, reference axis, and inertia loading are considered. Special conditions and accuracy for each of the three models are provided.

Uranium Ore Controls of the Happy Jack Deposit, White Canyon, San Juan County, Utah

Description: Abstract: The Happy Jack uranium deposit of White Carron, San Juan County, Utah, was studied in connection with an Atomic Energy Commission exploration program. The major uranium ore control is a paleostream channel containing sediments of the Shinarump conglomerate. Intrachannel controls include organic matter, lithologic variations, and channel "lows". Microscopic studies reveal that uraninite, the primary ore mineral, occurs as cement and as a replacement of organic material. Both the uranin… more

Neutron Streaming Through Boundaries in a Mock-Up of the SIR Rotating Plug

Description: This report is a summary of the neutron attenuation data which have been obtained at the Brookhaven shielding facility on a mock-up of the fuel-rod-unloading plug used in the KAPL Reactor. Before this program was initiated, a number of small scale tests had been made in the ORNL lid tank on carbon steel mock-ups of components of the rotating plug. The results of the tests indicated considerable neutron streaming through the vertical steel and air members of the plug. However, the lid tank sourc… more

Calculation of Average Flux in Moderator of Water Lattices by Means of a Relaxation Method

Description: The following report concerns the application of a relaxation mesh method for the determination of the average flux within the moderator of a light water moderated, 1.027 per cent U-235, hexagonal lattice with a volume ratio (V_H2O + V_Al)/V_Uranium of 4:1. It was hoped that the calculation would enable one to determine any differences in flux which might result from the fact that the unit cell is a hexagon instead of a cylinder. Because we were primarily interested in the effect due to geometr… more
