Report presenting an investigation of a model of the Convair B-58 airplane weapons system in the transonic tunnel for a range of Mach and Reynolds numbers. Results regarding drag characteristics, lift-curve slope, and longitudinal stability parameter are provided.

Memorandum presenting an investigation made at a Mach number of 1.93 to determine lift, drag, pitching-moment, and average downwash characteristics of several missile configurations. Five configurations with rectangular wings and tails of various spans were tested; each of the configurations had two locations of the wing relative to the tail.

"This note presents the results of a parametric study of heat-generating graphite plates with hydrogen coolant flowing through constant area passages. The heat generation within the graphite was assumed to have a distribution that allowed the centerline temperature of the plates to remain constant at 5000 F. The parametric variables were the mass flow rate per unit area, plate thickness, plate length, and passage hydraulic diameter. The machine calculations were coded by Ivan Cherry, T-1."

The Non-Production Fuel Reprocessing Program involves the chemical processing of valuable reactor fuels received from privately owned power reactors. It is necessary therefore, to accurately measure the fuel material received in order to insure proper payment to reactor operator and to provide the Atomic Energy Commission with appropriate accountability data. The volume measurement study described herein was conducted in order to determine the limits of accuracy that could be obtained in measuring relatively large volumes of solution under plant processing conditions.

Presently rotary drum filters are being used for plutonium oxalate slurry filtration in the 234-5 Building. Changing of the filter cloth used on a rotary drum is a time consuming operation which involves ever increasing radiation exposure to maintenance personnel. Consequently, studies were conducted in the 321 Building on a disk type filter which could be adapted for simple and quick ("one-nut") replacement of the filter medium.

From Summary: "Linearized theory is used to estimate the order of magnitude of the beneficial effects that can be obtained by shaping the body of a wing-body configuration to generate lift indirectly at supersonic speeds. The analysis applies to a class of wing-body configurations which is believed to exhibit the essential features of this type of interference; the body is cylindrical upstream of a wing which has supersonic edges and the parts of the body above and below the wing are each semicircular and of different radii. Calculations are presented for a Mach number of the square root of 2 for a particular family of bodies and a sonic-edge delta wing."

Memorandum presenting an investigation to determine the effect of camber on the drag of a body of revolution. The drag of a straight body of revolution was measured and compared with that of a body that differed only in that its center line was cambered in the form of a parabola. The addition of a small amount of camber was found to cause very little increase in the minimum foredrag of the model tested.

Report presenting an investigation of the aerodynamic characteristics of two full-scale supersonic propellers with a 6000-horsepower propeller dynamometer. One propeller had symmetrical NACA 16-series airfoil sections and the other was similar except for a blade-section camber and a slight difference in pitch distribution.

"The proportional-plus-flicker automatic pilot operates by a nonlinear principle whereby a fast-acting flicker servomotor response is combined with a low-speed proportional servomotor response for the purpose of obtaining supersonic stability and control. Essentially, the autopilot maintains a zero reference about which the output is proportional to the input. However, a flicker response overrides this proportional response at a fixed angle of gimbal displacement on either side of the zero gyroscope reference" (p. 1).

Report presenting an investigation of a model of the Convair B-58 airplane weapons system, including under conditions of long-range subsonic cruise and a supersonic dash. Results regarding drag characteristics, lift-curve slope, and longitudinal stability parameter are provided.

This paper discusses a remotely operated system developed to transport (raise and lower) a 1/2 gram radium gamma radiation source for calibration of the HAPO film badges and finger rings. The system employs the rotometer principle for positioning the source for operating purposes. An accurate timer is utilized to assure the desired exposure time.
