Liquid Hydrogen Bubble Chambers

Description: After the first hydrocarbon bubble chambers were built by Donald Glaser in 1952, work was started at Chicago and Berkeley to find if liquid hydrogen could be used as the working fluid in a bubble chamber. In the fall of 1953, it was found by the Chicago group that superheated liquid hydrogen could be made to boil under the influence of ionizing radiation, but no tracks were observed. The observation of tracks at Berkeley a few months later completed the proof that hydrogen was a usable bubble c… more

Effects of a J34 Turbojet Engine on Supersonic Diffuser Performance

Description: Report presenting testing of a translating cone inlet with a variable bypass at Mach numbers 1.6, 1.8, and 2.0 with both a choked exit plug and a J34 turbojet engine. The main difference between the two options was increased inlet subcritical stability with the engine. Results regarding basic diffuser performance, inlet stability, buzz amplitude and frequency, and diffuser-exit profiles are provided.

Effect of an Adjustable Supersonic Inlet on the Performance Up to Mach Number 2.0 of a J34 Turbojet Engine

Description: "A J34 turbojet engine was investigated at free-stream Mach numbers of 0.12 and 1.6 to 2.0 to determine the effect of supersonic inlet operation on engine performance. With the exception of ideal jet thrust, the use of generalized engine parameters correlated the engine data satisfactorily when the exit nozzle was choked. Large total-pressure distortions did not affect compressor efficiency" (p. 1).

Flight investigation of the effectiveness of an automatic aileron trim control device for personal airplanes

Description: "A flight investigation to determine the effectiveness of an automatic aileron trim control device installed in a personal airplane to augment the apparent spiral stability has been conducted. The device utilizes a rate-gyro sensing element in order to switch an on-off type of control that operates the ailerons at a fixed rate through control centering springs. An analytical study using phase-plane and analog-computer methods has been carried out to determine a desirable method of operation for… more

Investigation of a continuous normal-shock positioning control on the bypass of a supersonic inlet in combination with the J34 turbojet engine

Description: Report presenting an investigation of a normal-shock positioning control which utilized the bypass of a supersonic inlet to set the required air flow for a J34 turbojet engines to Mach number 2.0 in the supersonic tunnel. Continuous control without oscillations was obtained by use of the pressure signal from the small static probe. Calculated response time generally agreed with measured values.

A Summary of the History of Hanford Redox Plant Solvent

Description: The Redox solvent extraction process for the separation of uranium and plutonium from their fission products and from each other has operated on an over-all basis very successfully for more than four and one-half years. During this time, there have been occasional periods of high product losses and/or poor separation of fission products from uranium or plutonium as well as periods of poor operability due, among other things, to emulsification and entrainment. The search for the cause of these v… more

Use of Shadowgraph Technique in the Analysis of the Performance of Two Supersonic Axial-Flow Compressor Rotors Operating Over a Mean Radius Relative Inlet Mach Number Range of 0.85 to 1.7

Description: Report presenting shadowgraphs of flow patterns through the blade passage and ahead of a compressor rotor by shining parallel light rays approximately radially onto a rotor hub and upstream inner ring, which was painted white to serve as a screen.

An experimental investigation of a flat ram-jet engine on a helicopter rotor

Description: Report presenting the propulsive and aerodynamic characteristics of a flat ramjet engine suitable for use on a helicopter rotor and compared with previous tests of an equivalent engine with a circular cross section. The results indicate that the flat engine has higher values of propulsive thrust plus power-off drag than the circular engine. The power-off and drag characteristics indicate that the flat engine has lift-drag ratios about 3 times those obtained with the circular engine.

Plasters and Elastomers in Radiation Fields: A Preliminary Evaluation

Description: With the construction of nuclear reactors, a great deal of emphasis has been placed upon studying the effects of radiation on the solid materials of construction. It has become necessary to consider radiation exposure as an environmental entity along with others so established such as temperature, electrical and mechanical stress, chemical resistance, weather, etc. Problems concerning the study of the behavior of materials that are thus increased when radiation exposure has to be evaluated sing… more
