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.

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 prog… more

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.)

Radiative Capture of Protons in Ne²⁰

Description: Abstract: "A preliminary measurement of the Ne²⁰(p,γ)Na²¹ reaction cross section has been made. Targets were prepared by bombarding aluminum targets with neon ions. The neon concentration in the target was determined by elastic scattering of 1.5-Mev-protons. The yield of positrons from the reaction Ne²⁰(p,γ)Na²¹(β)Ne²¹ was identified by the 23-second half life of Na²¹."

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.

Transonic wind-tunnel investigation of the low-lift aerodynamic characteristics, including the effects of leading edge droop and thickness, of a thin trapezoidal wing in combination with basic and indented bodies

Description: Report presenting an investigation in the transonic tunnels to determine the aerodynamic force characteristics at low lift coefficients for a 2-percent-thick trapezoidal wing tested in combination with basic and indented bodies. The effects of wing leading-edge droop and wing thickness were investigated. Testing occurred over a range of Mach numbers and angles of attack.

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.
