100 Areas, January 29 through February 4, 1946
The B Pile operated 25 MW below rated power level without interruption during the week. The D Pile was shut down on January 29. During the shutdown 103 tubes were discharged. The shut down lasted for 15 hours. During operation after the shut down power was reduced to meet graphite temperature restrictions. The F Pile was run steadily throughout the week at 25 MW below rated level. Iron content in the process water averaged 0.015, 0.011 and 0.010 ppm at B, D, and F Areas, respectively. Examination of the slugs discharged from four corrosion tubes at F has been completed. A summary of conditions found in the vertical and horizontal aluminium thimbles at D and F during a recent inspection are given. Results are given on the graphite expansion problem.

100 Areas Technical Activities Report - Physics, January 1947
Four routine shutdowns were experienced during the month. A measurable amount of the excess reactivity held in the control rods at the first of the month has been lost in the decrease in the average accumulated exposure of all the metal in the pile. The vertical safety rod guides have been measured for vertical alignment by the Maintenance Dept. A definite pattern has been found in the misalignment of the guides. The horizontal rod thimbles were borrowed on January 2, 1947 to see if any leaks were present. No leaks were observed but No. 2 Rod and No. 8 Rod had heavy gouge marks along the longitudinal axes. Several thimbles contained white corrosion. During the month two new bismuth tubes were established, 2871-D and 2877-D. This now gives the desired pattern of ten bismuth tubes.

300 Area, February 12 through February 18
Extrusion was run on one day, February 2, and a total of 271 billets (178 Type G, 12 type BT, and 81 red band) were processed. Two failures occurred among the red band billets; UM 6610 had begun to melt in the furnace and TX 3323 disintegrated on being extruded through the die. Samples of these billets are being checked chemically and metallurgically in an attempt to ascertain the cause for the hot-short characteristics of these billets. A sample cut from a rod which possessed zero strength (fell apart under no stress other than its own weight) at extrusion temperature was found to contain a large amount of microconstituent not ordinarily found in appreciable quantity on uranium sections. The distribution and appearance of the excess phase suggested at least partial liquation at the working temperature and it could, therefore, be responsible for the hot-short tendency.

Addition of Heat to a Compressible Fluid in Motion
From Introduction: "The purpose of this report is to summarize, without extended proofs, the results of a study of a simplified model of nonadiabiatic, compressible fluid flow, both subsonic and supersonic, and to state these results in a form that will make them immediately useful in providing a theoretical background for current technical problems of high-speed combustion.

Aerodynamic Characteristics at High Speeds of Full-Scale Propellers Having Different Shank Designs
"Tests of two 10-foot-diameter two-blade propellers which differed only in shank design have been made in the Langley 16-foot high-speed tunnel. The propellers are designated by their blade design numbers, NACA 10-(5)(08)-03, which had aerodynamically efficient airfoil shank sections, and NACA 10-(5)(08)-03R which had thick cylindrical shank sections typical of conventional blades. The propellers mere tested on a 2000-horsepower dynamometer through a range of blade-angles from 20 degrees to 55 degrees at various rotational speeds and at airspeeds up to 496 miles per hour" (p. 1).

Aerodynamic Characteristics of Four NACA Airfoil Sections Designed for Helicopter Rotor Blades
"The purpose of the present work is to extend the previous investigation and to derive additional airfoil sections designed to minimize the undesirable characteristics of the previously tested airfoils. The tests of these additional airfoils were made in the Langley two-dimensional low-turbulence tunnel (LTT)" (p. 2).

Aerodynamics of Rotating-Wing Aircraft With Blade-Pitch Control
"In the present report, with the aid of the usual computation methods, a rotor is investigated the pitch of whose blades is capable of being controlled in such a manner that it varies linearly with the flapping angle. To test the effect of this linkage on the aircraft performance, the theory is applied to an illustrative example" (p. 1).

An Analysis of Jet-Propulsion Systems Making Direct Use of the Working Substance of a Thermodynamic Cycle
From Summary: "The results of the analysis showed that the combined efficiency, which is unacceptably low at speeds less than 300 miles per hour, becomes nearly equal to that of conventional power plants of current design at 500 miles per hour. It was also shown that the efficiency will be increased considerably as the physical limitations on cycle temperature and blower speed are raised and as the efficiencies of the system components are improved."

An analysis of the fatigue life of an airplane wing structure under overload conditions
From Introduction: "Fatigue life expectancy in normal transport operations was investigated in reference 1 and was found to be of equal importance with single-gust life. The effect of overload operation of transport airplanes on the probability of encountering single critical gusts was investigated in reference 2 and the frequency of critical gusts was found to increase rapidly with overload. The effect of overload operation on fatigue strength, however, has not heretofore been evaluated, hence the investigations of references 1 and 2 are combined herein to permit such evaluation and to determine the relative importance of fatigue and single-gust failures under conditions of overload operation."

Analytical Comparison of a Standard Turbojet Engine, a Turbojet Engine with a Tail-Pipe Burner, and a Ram-Jet Engine
From Introduction: "Experimental investigations (reference 1) have shown that in some cases the thrust can be more than doubled by means of tail-pipe burning. A comparison is made of a standard turbojet engine, whose thrust is augmented by tail-pipe burning, and a ram-jet engine. The performance characteristics for the ram-jet engine were computed entirely from theoretical considerations and on the assumption that the burner-inlet velocity was constant."
