Measurements of Aileron Effectiveness of the Bell X-1 Airplane at Mach Numbers Between 0.9 and 1.06

Description: "Abrupt rudder-fixed aileron rolls have been made with the Bell X-1 airplane in powered flight at Mach numbers between 0.90 and 1.06 at about 40,000 feet pressure altitude. These aileron rolls indicate that the aileron effectiveness for large deflections at Mach number 0.94 is only one-fourth the value at Mach number 0.82, and the effectiveness at Mach number 1.06 is slightly greater than at Mach number 0.94" (p. 1).

Free-flight zero-lift drag-rise measurements of equivalent bodies of revolution of several versions of the Douglas XF4D-1 airplane at transonic speeds: TED No. NACA AD 394

Description: From Summary: "Free-flight tests have been conducted with small equivalent bodies of revolution representing different versions of the Douglas XF4D-1 airplane to determine the reduction in drag that would result from various modifications to the airplane. Results indicated that, at Mach numbers greater than 1, considerable reduction in drag would result from a thinner wing and tail, a reduction in wing-fillet thickness, and modified forward and rearward fuselage lines."

Development of vanadium-phosphate catalysts for methanol production by selective oxidation of methane. Quarterly technical progress report No. 1, October--December 1992

Description: Amax R&D will perform laboratory scale development of a promising, practical catalyst for the selective oxidation of methane to methanol. The primary component of this catalyst is vanadium-phosphate (VPO) which has shown good activity and selectivity in the partial oxidation of n-butane and propane but has not been studied in detail for methane oxidation. The goal of the project is to develop a catalyst which allows methane oxidation to methanol to be conducted at high conversion and selectivit… more

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts. Quarterly technical progress report, December 14, 1990--March 14, 1991

Description: The primary concern of the study during this period has been to examine the origin and basis of the several nonconforming NMR lines reported in our earlier study. Previous studies by earlier investigators indicate that (a) the product distribution in the conversion of synthesis gas to liquid fuels is dependant on the copper/cobalt ratio and (b) that the catalytic results reported by different groups of investigators using the IFP prescription (4) are widely divergent. These observations prompte… more

NQR-NMR studies of higher alcohol synthesis Cu-Co catalysts. Quarterly technical progress report, December 15, 1991--March 15, 1992

Description: During this period, we focused our attention in analyzing the magnetic nature of the extensively used trimetallic catalyst system Cu-Co-Cr for the production of higher alcohols. We believe that there could be some correspondence between the catalytic and magnetic behaviors of the transition metal catalyst systems. Both the morphology and metallic charge distribution of the particles are known to govern the catalytic as well as the magnetic properties of the system.

Technology development for cobalt F-T catalysts

Description: A computer search of both the open and the patent literature was conducted in order to ascertain the current state of cobalt-based catalyst technology for F-T synthesis. Two series of literature searches were conducted, one dealing specifically with cobalt catalysts for F-T synthesis and the other focusing on the preparation and/or characterization of supported cobalt catalysts including those not used for F-T synthesis. An initial screening of the literature was carried out by examining the 94… more

Integrated system for production of neutronics and photonics calculational constants. Major neutron-induced interactions (Z less than or equal to 55): graphical, experimental data

Description: This report (vol. 7) presents graphs of major neutron-induced interaction cross sections in the Experimental Cross Section Information Library (ECSIL) as of July 4, 1976. It consists primarily of interactions where a single data set contains enough points to show cross-section behavior. In contrast, vol. 8 of this UCRL-50400 series consists of interactions where more than one data set is needed to show cross section behavior. Thus, you can find the total, elastic, capture, and fission cross sec… more

U.S. Coins: Replacing the $1 Note with a $1 Coin Would Provide a Financial Benefit to the Government

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Since coins are more durable than notes and do not need replacement as often, many nations have replaced lower-denomination notes with coins to obtain a financial benefit. GAO has estimated the annual net benefit to the U.S. government of replacing the $1 note with a $1 coin four times over the past 20 years, most recently in April 2000. Asked to update its estimate, GAO (1) estimated the net benefit to… more
