From purpose of report: The primary purpose of this report and its appendices is to transmit to the AEC the principal results of the experimental and engineering work done on the low-temperature process and to describe the factors which led to the designs finally adopted.

On 2/8/1950, there was mined from process tube 2273 in D pile at Hanford a quantity of graphite power, which was expected to show the most extensive radiation damage of any graphite available at that time. A series of samples of this powder were annealed in 100 degrees increments from 100 degrees to 2000 degrees C at this labaoratory. There were returned to Hanford and shipped by them to the National Bureau of Standards for total stored energy measurements. The present memorandum is comprised of a description of the annealing procedure used here, curves giving the detailed annealing history of each sample, and various curves derived from data obtained from these samples at Hanford and at the National Bureau of Standards.

Report presenting the results of a free-flight investigation of two drag research models equipped with canopies for a range of Mach numbers from 0.8 to 1.5. The main difference between the models was the location of the canopy, which was at the 15-percent fuselage station on one model and the 25-percent fuselage station on the other. The additional drag due to the canopies was about 10 to 20 percent of the total configuration drag at supersonic speeds.

Memorandum presenting a description of a method of telemetering skin temperature using a small resistance wire pickup with a time constant of less than 0.003 second to determine boundary-layer heat-transfer coefficients. An evaluation of the accuracy of the method of measuring the heat-transfer coefficient is given for a particular application.

"Flutter tests of sweptback cantilever wing models have been made in a small intermittent two-dimensional supersonic tunnel where the testing technique involved changing the structural parameters so that the models would flutter at the tunnel design Mach number of 1.3. Data for 21 models covering sweep angles from 30 degrees to 60 degrees and with varying parameters are included" (p. 1).

Report presenting the use of Theodorsen's propeller theory to calculate the performance of a dual-rotating propeller with nonideal load distributions. Results regarding the propeller characteristics were made for several blade-angle settings and flight Mach numbers.

This report follows an investigation on Great Lakes Carbon with the objectives to demonstrate their ability to make and F process purify reactor carbon on a commercial scale; and construct an F process pilot plant and use it in a survey of U.S. petroleum cokes to discover additional supplies of raw coke suitable for making reactor grade carbon.

Report documenting the suitability of Indiana for plant locations to produce synthetic liquid fuels, based on raw materials such as oil shale, natural gas, and coal.
