An Investigation of the Longitudinal Characteristics of the X-3 Configuration With Wing and Horizontal Tail Surfaces of Aspect Ratio 3.0 by Means of Rocket-Propelled Models: Results at High Lift Coefficients

Description: "A rocket-propelled model of the X-3 configuration equipped with an all-movable tail of aspect ratio 3.0 has been flown to determine the longitudinal characteristics of this configuration at high lift coefficients. An analysis of the response of the model to rapid deflections of the horizontal tail gave information on lift, drag, longitudinal stability, and longitudinal trim change. The primary result of the tests was that the configuration was indicated to have very unstable tendencies at lift… more

Investigation of the Effects of Twist and Camber on the Aerodynamic Characteristics of a 50 Degrees 38 Minutes Sweptback Wing of Aspect Ratio 2.98: Transonic-Bump Method

Description: "An investigation of two semispan wings swept back 50 degrees 38 minutes was conducted in the Langley high-speed 7- by 10-foot tunnel over a Mach number range of 0.68 to 1.15 by use of the transonic-bump technique. This paper presents the results of the investigation of wing-alone and wing-fuselage configurations of the two wings; one was an untwisted uncambered wing and the other was the same wing but incorporated twist and camber designed to give uniform load at a lift coefficient of 0.25 at … more

The Use of Two-Dimensional Section Data to Estimate the Low-Speed Wing Lift Coefficient at Which Section Stall First Appears on a Swept Wing

Description: Report discusses a procedure for estimating the wing lift coefficient for and spanwise location of the first occurrence of section stall on a swept wing. It has been modified from a method used to calculate the same information for unswept wings. The effects of split flaps, leading-edge modifications, and fences are described.

Resolution of Annealing Experiments for the Study of Nonequilibrium States

Description: The two techniques for conducting annealing experiments for the purpose of determining the distribution of atoms of a solid among non equilibrium states are considered. Related definitions for resolving power for annealing with steadily rising temperature and for annealing at a series of fixed temperatures are given. The necessary separation of activation energies for the resolution of two different non equilibrium states is found to be greater in the case of a steadily rising temperature, but … more

Increased water flows and pressures to 105 buildings

Description: Document HW-21096, inquires regarding changes in equipment, so that various proposed flows of process water to each of the present production units, at several 105 control room pressures, may be effected. The proposed conditions are shown in table form in the report. For the purpose of calculations upon which this letter is based, the pressure used here is that which is recorded at the 105 control room ``inlet`` panel. It is actually the top of riser pressure, plus static head between the recor… more

Canning depleted uranium : production test 313-110-M, final report

Description: From summary: "Uranium billets deficient in U235 were subjected to the normal successive steps in the slug fabrication process; viz., rolling, machining, and canning. No unusual behavior was observed at any point in the process, thus indicating that the depleted metal from the standpoint of mechanical properties can be considered equivalent to normal uranium."

Discriminator Calibrator

Description: To calibrate a pulse height discriminator, the amplitude of the calibrating pulse must be known. If the amplitude is known, the discriminator dial may be calibrated in terms of the input signal required to just trip it. This is the purpose for which the Discriminator Calibrator was designed. It produces pulses of variable but known amplitude with a rep. rate variable from 3 pps to 4000 pps. The main use of this unit at the UCRL is in conjunction with scalers at fixed counting locations.
