DESCRIPTION OF ORNL POOL TYPE CRITICAL FACILITY

Description: The Pool Type Critical Facility (PTCF) is a low powered, highly eariched (90 to 95% U/sup 235/) ordinary light water cooled and moderated, beryllium oxide reflected assembly. It is generally similar to the present BSR at ORNL, the principal modification being that the grid plate is arranged to accommodate both ORR and BSR fuel elements. The PTCF is located in the northwest corner of the existing BSR pool. The 9 x 7 lattice provides 63 fuel, control rod, or reflector positions. (W.D.M.)

The design and cascade tests of free-streamline and full-contour 160 degrees turning supersonic-turbine-blade sections

Description: Report presenting a study of the flow characteristics of two supersonic-impulse-turbine-blade sections designed for a turning angle of 160 degrees. The primary difference between the two sections was the cutting away of a large portion of the convex surface and the presence of a free streamline as the boundary of flow in the passage. Results regarding the full-contour blade, free-streamline blade, and a comparison of the two are provided.

Experimental investigation of effects of simulated nacelles and wing-root freedoms on supersonic flutter characteristics of a cambered, modified, swept, tapered wing

Description: Report presenting an investigation to determine the effects of simulated engine nacelles and wing-root freedoms on the flutter characteristics of a cambered, modified, swept, tapered, semispan wing through a range of Mach numbers. Wings were tested with and without nacelles and with the model restrained, free to roll, and free to translate in the vertical direction. Results regarding the effect of nacelles, flutter boundary, and effect of wing-mount freedom are provided.

A Flight and Analog Study of the Effect of Elevating the Radar-Boresight Axis Upon Stability and Tracking Performance of an Automatically Controlled Interceptor

Description: Report presenting flight and analog-simulator tests with a prototype automatic interceptor in order to study the effects of elevating the radar-boresight axis on the stability and tracking performance of the system. Results regarding effects of interceptor rolling motion upon tracking errors, similarity of flight results and analog-computer results, effect of elevating the radar-boresight axis upon stability, effect of elevating the radar-boresight axis upon the required bank-angle feedback, and application of the principle of elevated radar-boresight axis are provided.

A Flight and Analog Study of the Effect of Elevating the Radar-Boresight Axis Upon Stability and Tracking Performance of an Automatically Controlled Interceptor

Description: Report presenting flight and analog-simulator tests with a prototype automatic interceptor in order to study the effects of elevating the radar-boresight axis on the stability and tracking performance of the system. The interceptor was designed to perform the lead-pursuit type of attacks and test runs were made in flight and on the analog simulator with and without lead-angle computation. Results regarding the effects of interceptor rolling motion upon tracking errors, similarity of flight results and analog-computer results, effect of elevating the radar-boresight axis upon stability, and application of the principle of elevated radar-boresight axis are provided.

Flight evaluation of the lateral stability and control characteristics of the Convair YF-102 airplane

Description: Report presenting the lateral stability and control characteristics of the Convair YF-102 airplane during flights for the NACA research program. The investigation included gradually increasing sideslips, rudder-fixed aileron rolls, rudder pulses, and trim runs at two different altitudes over the test Mach number range. The lateral handling characteristics appeared satisfactory when viewed in terms of gradually increasing sideslips.

A Flight Investigation to Determine the Effectiveness of Mach Number 1.0, 1.2, and 1.41 Fuselage Indentations for Reducing the Pressure Drag of a 45 Degree Sweptback Wing Configuration at Transonic and Low Supersonic Speeds

Description: Report presenting a flight investigation to determine the effectiveness of three fuselage indentations for reducing the pressure drag of a 45 degree sweptback-wing-body configuration at a range of Mach numbers. The results indicate that the supersonic area rule can be used to determine indentations with low pressure drag over a Mach number range in which the blunt leading edge is subsonic. Information about total drag and pressure drag is provided.

The Heat of Combustion of Tetraethyldiborane

Description: "The net heat of combustion of a sample of tetraethyldiborane was found to be 20,400 plus or minus 130 Btu per pound for the reaction of liquid fuel to gaseous carbon dioxide, gaseous water ,and solid boric oxide. The measurements were made in a Parr oxygen bomb calorimeter and the combustion is believed to have been 99 percent complete. A more reasonable value for the net heat of combustion would therefore be 20,600 plus or minus 130 Btu per pound" (p. 1).

HIGH-STRENGTH MATERIALS FOR PRESSURIZED-WATER IN-PILE TUBES

Description: The preliminary work done by Westinghouse on properties of materials suitable for the in-pile testing facility was reviewed. Information was collected on a selected list of promising materials in the following classificrtions: alloy steels, chromium steels, precipitation-hardening stainless steels, and superalloys. On the basis of the information obtained from Westinghouse, from the literature survey, from Battelle files, and from visits to producers, it is recommended that Phase II of the program be confined to Inconel X hot rolled and aged, AM-350 subzero cooled and tempered, and Discaloy solution treated and aged.
