Report presenting an investigation to study the use of various high-lift devices on the horizontal tail of a canard airplane model as a means of increasing the allowable center-of-gravity travel. The results indicated that the large increases in allowable center-of-gravity travel could be obtained using the devices. Results regarding the basic aerodynamic data, effect of tail configuration on the allowable center-of-gravity travel, and a comparison of measured and predicted values of the allowable center-of-gravity travel are provided.

Report presenting an investigation in the transonic tunnel to determine the dynamic and static stability characteristics of the Mark-6, Mark-4, TX-13, and Mark-5 special weapons and the effects of modifications of them for a range of Mach numbers.

Report presenting an investigation to determine the effect of leading-edge chord-extensions on high-lift pitching moment and performance characteristics at subsonic and transonic speeds. Three models with the same wings were used. Results regarding low-speed development and high-speed characteristics are provided.

Report presenting aerodynamic characteristics in steady roll on a complete model and its component parts. The model consisted of a wing and horizontal tail with a 45 degree sweepback at the quarter-chord line, a taper ratio of 0.6, an aspect ratio of 4, and NACA 65A006 airfoil sections parallel to the plane of symmetry. Results regarding rolling moment due to rolling, yawing moment due to rolling, and lateral force due to rolling are provided.

Report presenting an investigation in the transonic tunnel to determine the aerodynamic characteristics of a wing-fuselage combination with a 45 degree sweptback wing with NACA 65A006 airfoil sections, an aspect ratio of 4, taper ratio of 0.6, and incorporating outboard leading-edge slats. Results lift characteristics, influence of slats on wing pressure distribution, drag characteristics, lift-drag ratio characteristics, and pitching-moment characteristics are provided.

Report presenting a wind-tunnel investigation to study the effects of operating propellers on the low-speed longitudinal characteristics of a four-engine tractor airplane configuration. The coefficients of lift, longitudinal force, pitching moment, propeller thrust, and propeller power are provided. Tests were conducted at a range of Mach and Reynolds numbers.

The continuous plutonium concentration facilities proposed for the Purex Plant consist of a stripper-concentration unit in which the organic is removed and a portion of the required evaporation is accomplished, plutonium concentrator (No. 1 Pu Conc.) in which the final plutonium concentrate is produced, and a second concentrator which re-evaporates the totally condensed overhead from the No. 1 Pu Concentrator. In this report the Purex concentration ``package`` has been examined to determine whether the design is suitable for concentrating the various Redox 3BP solutions which may be produced (variable nitric acid to plutonium ratios) during operation at Redox Phase II processing rates. In Appendix {Lambda} a short-cut method is presented for the calculation of the operating conditions to be employed around the No. 1 and No. 2 Pu concentrators to produce a desired Pu-HNO{sub 3} product stream from a given feed solution. This method is considerably simpler than the trail-and-error solutions generally employed for such problems.

The objective of this test is to evaluate the effects of low pH process water and unfiltered river water on pile operation. This report is dated September 21, 1953.

The potentialities of unfiltered Columbia River water as a pile coolant have been discussed in a recent survey of the available information on the subject. The survey report points out the gains which the use of unfiltered water offers, and proposes a logical framework of treatment by chemical additives which appears to have a reasonable probability of successfully developing a far less expensive pile coolant. A comprehensive testing program is now being initiated to obtain the required experimental information concerning the effects of unfiltered water on corrosion, film formation, and effluent activity. The purpose of this report is to outline the range of variables to be studied; to discuss the various experimental techniques to be used; and to establish the anticipated scheduling of the several phases of the program.
