"Liquid Rocket Propellant Compatibility Testing."
Material-propellant compatibility as related to liquid rocket propulsion system design criteria is discussed and applicable test methods to derive usable design data are presented. Test methods, with emphasis on metallic materials, are discussed and the shortcomings of a number of these test methods are pointed out. These tests include static immersion tests, stress-corrosion tests, flow tests, impact tests, and tests to determine the effect of cracks and notches in metals on compatibility. A general outline for the evaluation of metallic and nonmetallic materials with respect to propellant compatibility is presented. -

Handwritten letters from R. D. McKinney to S. Schiffman.
In these letters, R. D. McKinney tells S. Schiffman that he will have to take all McKinney's stocks as his landlord has taken all his cotton stock to pay his rent before McKinney could pay S. Schiffman. In the second letter, McKinney asks S. Schiffman to send him two dollars to finish paying off the cotton pickers. The final letter is a request for meat and coffee on credit. -

"X-ray television inspection of aerospace weldments : Television x-ray image enlargement system for inspection."
A sensitive new television X-ray image enlargement system has been developed under sponsorship of Watertown Arsenal Laboratories (Army Materials Research Agency) by the Department of Welding Engineering of The Ohio State University. Now commercially-available through Philips Electronics Instruments (Norelco), complete systems have been in service since January 1963 in aerospace, electronic, and other facilities. Such users report highly- satisfactory performance and unusual reliability in service. The new X-ray system permits in-motion or stationary examination of critical aerospace materials, components, and systems such as sheet materials, weldments, brazed joints, electronic components, printed circuit assemblies, small mechanisms, and biological specimens. -

"The role of simulation in the development of an automatic checkout system"
For publication in Luftfahrttechnik Raumfahrttechnik. Discusses the uses and advantages to using simulations. -
"Signal distribution in automatic checkout systems."
This paper deals with several selected aspects of the signal distribution in automatic checkout systems. These are: 1) The use of relay matrices as control elements; 2) The inclusion of self-checking capabilities; 3) Problems of systems integration. These aspects are not unique to automatic checkout systems. However, due to the nature of automatic checkout systems as presently being designed around digital circuitry, they find either fuller or different applications than in other types of systems. Also, while they are on the surface somewhat disconnected in nature, they tend to interrelate during the implementation of an automatic checkout system. -

Report from the Alabama sesquicentennial celebration held in Huntsville, Alabama.
This report was written by Frederic F. Mellen of Jackson, Mississippi. Mellen was a descendant of Arthur F. Hopkins, a Lawrence County delegate to the 1819 constitutional convention. Mellen recounts his experience at the sesquicentennial events on August 2, 1969, including the birthday luncheon and the ceremony commemorating the signing of the 1819 constitution. He notes that "it is pleasing to see and realize how Huntsville has grown, and that now it is a vast educational and scientific research and development center." -

Theoretical liquid propellant performance calculations
Archive copy is a photocopy.; The purpose of these writings is to compile in one volume the basic elements of thermodynamics and gas dynamics which are useful in the evaluation of thrust chamber performance. It is presumed that the reader will have had an elementary course in thermodynamics and gas dynamics. The discussion of topics useful in evaluating thrust chamber performance is, of necessity, limited to these physical effects amenable to other areas that are as yet in the research stage of development. The author would like to take this opportunity to express his gratitude to Mr. G. S. Gill for many stimulating discussions on this subject. Thanks are due to Mr. D. J. Kuyper for permission to utilize his discussion on elastic-plastic strain and its application to nozzle throat area change. Finally, the author wishes to express his gratitude to his wife, Alice, who typed the bulk of the manuscript. -

"Communication-System Blackout During Reentry of Large Vehicles".
This paper was published in the Proceedings of the IEEE, volume 55, number 5, May 1967.; ABSTRACT: Much of the theoretical research on reentry blackout is in a format difficult for the communications design engineer to use in his system analysis. This paper derives simplified equations for the average sheath power loss that may be added (in dB) to the usual space loss to obtain an approximate total propagation loss. The plasma and sheath properties are discussed in detail but largely without supporting mathematics, in order to give the design engineer a better understanding of the overall problem. For the same reason and to provide insight into the final results, the average radiated power is found, using both intuitive and rigorous techniques. Several graphs of plasma properties are included in the development as an aid to numerical computation, and results are compared with the work of other authors. -

"Digital Simulation of an Aerospace Vehicle."
The rapid development of computer technology and the creation of new engineering oriented languages has established that general purpose digital computers are now extremely suitable to perform simulation of large scale physical systems. With Aerospace Vehicle Simulation (AVS), an effort has been undertaken at MSFC to simulate continuous and discrete dynamics of an aerospace vehicle and its ground support equipment on a large digital computer. This simulation produces a copy of the physical vehicle configuration and its functions in the form of a large scale mathematical model in the computer. AVS will be an essential part of an integrated information system which can be used by several laboratories and offices at MSFC for the design, checkout, test, and management of aerospace vehicles. -
