Aerodynamic Loads on an External Store Adjacent to a 60 Degree Delta Wing at Mach Numbers From 0.75 to 1.96

Description: Report presenting an investigation to determine separately the aerodynamic characteristics of a Douglas Aircraft Company store and a semispan delta-wing-fuselage configuration in the presence of one another. The store was located at the 50-percent-semispan station with the store nose both ahead of and behind the wing leading edge for two longitudinal and three vertical positions.

An analog study of the relative importance of various factors affecting roll coupling

Description: From Introduction: "In this study wide variations in many of the pertinent aerodynamic were investigated at subsonic and supersonic speeds. The effects of large changes in principal axis inclination and mass distribution are also included. The primary purpose of this paper is to summarize the information obtained from the analog calculations and to compare the results with the trends predicted from a slightly modified version of reference 2."

A Brief Investigation of the Effect of Waves on the Take-Off Resistance of a Seaplane

Description: Report presenting testing to determine the resistance of a model of a seaplane with a length-beam ratio of 15 and a wing loading of 120 pounds per square foot was determined in smooth water and three wave heights under various conditions of load, speed, elevator setting, angle of dead rise, and center-of-gravity position.

Bulk ThO2, a Reactor Material

Description: Thorium, a fertile material, is of interest to the Reactor Program in the production of U233. Thorium can be extracted and processed to a very pure bulk metal for fabrication into solid fertile elements. There are advantages, technical and economic, for using fabricated bulk thorium dioxide rather than the metal in some applications. It is the purpose of this paper to point out these advantages and to present briefly the technology related to fabrication, radiation damage and chemical processin… more

Comparison of the Minimum Drag of Two Versions of a Modified Delta-Wing Fighter as Obtained From Flight Tests of Rocket-Boosted Models and Equivalent Bodies Between Mach Numbers of 0.80 and 1.64

Description: Report presenting an investigation to determine the reduction in minimum drag that could be obtained at supersonic speeds by redesigning the fuselage and reducing the wing and tail thickness of a modified delta-wing fighter-type airplane. Results regarding the mass-flow ratio, total-pressure recovery, and drag are provided.

THE DETERMINATION OF NIOBIUM IN URANIUM-NIOBIUM ALLOYS

Description: Niobium is determined as the peroxy complex in concentrated sulfuric acid by photometric measurement at 360 m mu . Uranium interference is cancelled by using a solution of the sample for reference in the photometric measurement. The method covers the determination of niobium in uranium --niobium alloys made from pure melting stock. Molybdenum interferes and must be removed if present. Zirconium does not interfere. The calibration curve covers a concentration range from 0.2 to 5.0 mg. (auth)

Elevated-Temperature Fatigue Properties of Two Titanium Alloys

Description: Report presenting an investigation to evaluate the unnotched fatigue properties of two titanium alloys at elevated temperatures. A variety of temperatures were tested and the results are provided in tabular form and as curves of stress versus cycles to failure for each test temperature. Both alloys were found to have potential use at the temperature ranges investigated.

EXAMINATION OF TITANIUM PULSE FEEDER DIAPHRAGM FAILURE

Description: A Ti pulse feeder diaphragm failed by cracking after 450 hr service in the Homogeneous Reactor Test mock-up. The diaphragm, which was made of MST Grade III Ti, was vibrated at 78 cpm at 40 to 50 deg C. One side of the diaphragnn was exposed to demineralized H/sub 2/O and the other side was exposed to 10g U/l UO/ sub 2/SO/sub 4/ solution. The main corrosion product was TiO/sub 2/. (W.L.H.)

An Experimental Investigation of Sting-Support Effects on Drag and a Comparison with Jet Effects at Transonic Speeds

Description: "This paper presents the results of an investigation of sting-support interference on afterbody drag at transonic speeds. Stings with varying diameter, cone angle, and cylindrical length were tested at the rear of a model with various afterbody shapes. The data were obtained at an angle of attack of 0 deg. and at Mach numbers from 0.80 to 1.10. It was found that, in general, the addition of a sting caused a drag reduction" (p. 1).

Flight Investigation to Determine the Effect of Jet Exhaust on Drag, Trim Characteristics, and Afterbody Pressures of a 0.125-Scale Rocket Model of the McDonnell F-101A Airplane

Description: "A flight investigation was conducted to determine the effect of jet exhaust on the drag, trim characteristics, and afterbody pressures on a 0.125-scale rocket model of the McDonnell F-101A airplance. Power-off data were obtained over a Mach number range of 1.04 to 1.9 and power-on data were obtained at a Mach number of about 1.5. The data indicated that with power-on the change in external drag coefficient was within the data accuracy and there was a decrease in trim angle of attack of 1.27 de… more

Hot Semiworks summary: Run PX-13

Description: This report provides a summary of the Hot Semiworks Unit Run PX-13. During Run PX-12 acceptable HA Column decontamination was demonstrated; however, generally under unstable column operating conditions. The principal objectives of PX-13 were: To duplicate the high PX-12 decontamination factors under stable HA Column operating conditions; to study the effects of fresh solvent, IO Column CP carbonate washed solvent, and IO Column Technical grade carbonate washed solvent on A Column decontaminatio… more
