Communication Facility EMP Assessment. Sanitized( Book )

4 editions published in 1979 in English and held by 4 WorldCat member libraries worldwide

The Commander-in-Chief and the Defense Nuclear Agency (DNA) have undertaken an Assessment of Communications for Hardening to Electromagnetic Pulse to assess the vulnerability of the Command's Control, Communication and Computer (C4) Networks to electromagnetic pulses from high altitude nuclear bursts and to provide recommendations for hardening as may be required. Networks are used to link with the National Command Authority (NCA), subordinate and component headquarters, and the forces. The Boeing Aerospace Company has developed and validated analytical techniques to predict the functional responses of a communication facility to the environment produced by an electromagnetic pulse (EMP) scenario. The analytical capability has been applied to selected elements of the C4 Networks to develop response predictions in terms of upset and damage of facility equipment and functional impairments of facility communications capabilities. Keywords: Electromagnetic pulse (EMP), Hardening concept, Safety margin, Survival confidence, Upset thresholds, Command and control systems, Damage thresholds, Critical equipment, Hardening design package

PRESTO Digital Computer Code User's Guide. Volume I. System Overview( Book )

2 editions published between 1977 and 1980 in English and held by 2 WorldCat member libraries worldwide

PRESTO, an integrated system of computer codes, has been developed for the PREMPT program to perform EMP response analysis of communications systems. Volume One of the PRESTO User's Guide presents an overview of the entire PRESTO system and an introduction to the material contained in the other volumes (two through six) of the PRESTO User's Guide series. PRESTO provides engineering users with a tool for expeditiously analyzing electronic systems to determine electromagnetic pulse (EMP) effects. It is expected that users have a basic knowledge of digital computer usage, including FORTRAN. PRESTO consists of three groups of codes: an executive code, application codes, and a modeling library. The executive code provides the interface between the engineering user and the application programs which perform the calculations requested by the user. The modeling library contains subroutines used to model the electromagnetic response of signal cables, power systems, and ground systems. PRESTO interprets the user input, performs the required computation, and generates the output specified by the user. A modular approach is used in PRESTO to achieve maximum flexibility. The modularity of PRESTO and the independence of the executive control program facilitates the incorporation of additional application codes and modeling libraries applicable to system analyses other than for EMP effects

Future Orbital Transfer Vehicle Technology Study, Volume I - Executive Summary( Book )

2 editions published in 1982 in English and held by 1 WorldCat member library worldwide

This study has the objective of identifying missions for future orbit transfer vehicles (1995-2010) and defining the technology, operations and vehicle concepts that satisfy the transportation requirements. Several issues were examined. The first involved comparison of reusable space and ground based LO2/LH2 OTV's. Both vehicles used advanced space engines and aero assist capability. The SB OTV provided advantages in life cycle cost, performance and potential for improvement. The second issue was the comparison of an all LO2/LH2 OTV fleet with a fleet of LO2/LH2 OTVs and electric OTV's. The normal growth technology electric OTV used silicon cells with heavy shielding and argon ion thrusters. In this case, the LO2/LH2 OTV fleet provided a 23% advantage in total transportation cost. The third issue dealt with the impact of accelerated technology. An accelerated technology LF2/LH2 OTV provided improvements in performance relative to LO2/LH2 OTV but had higher DDT & E cost which negated its cost effectiveness. The accelerated technology electric vehicle used GaAs cells and annealing but still did not result in the mixed fleet being any cheaper than an all LO2/LH2 OTV fleet. The study conclusion is that reusable LO2/LH2 OTV's can serve all general purpose cargo roles between LEO and GEO for the foreseeable future. The most significant technology for the second generation vehicle would be space debris protection, on-orbit propellant storage and transfer and on-orbit maintenance capability

Processing, Fabrication, Characterization and Device Demonstration of High Temperature Superconducting Ceramics( Book )

1 edition published in 1990 in English and held by 1 WorldCat member library worldwide

Success with organometallics, citrates, and sintered powder compacts has resulted in two approaches for further development of strain tolerant conductors. They are, thin fibers and tapes, and bulk monoliths. A thorough understanding of the phase relationships in high temperature superconductors, including those phase relationships exhibited by the oxygen sublattice has been developed. This has allowed approaches for addressing the weak-link problem. Processes are being developed to reduce the grain size of fibers, tapes and monoliths. This approach offers the potential to deliver strong, fine-grained material and, with the correct alteration of grain boundaries, the elimination of poor electrical conduction across the weak-links. Other facets of this approach include attempts to texture the fine grains, produce adequate porosity to ensure good oxygenation, and the possible incorporation of silver for matrix strengthening. Work was pursued for producing candidate material for devices based on controlling high temperature peritectic reactions, for example seeding of fibers and tapes with yttrium oxide. The goal of this program is to develop material processes for new high temperature superconducting ceramics and to demonstrate these processes in a high current device. Keywords: Current density.

Integrated Cuing Requirements (ICR) Study: Feasibility Analysis and Demonstration Study( Book )

1 edition published in 1983 in English and held by 1 WorldCat member library worldwide

The goal is the Integrated Cuing Requirements (ICR) Study was to consolidate and synthesize existing human sensory/perceptual data, principles and models in a manner which would make this information readily accessible and useful to the community of aircrew training device (ATD) design engineers. There exists an extensive body of research literature on human perception which could potentially be of value in the specification, design, and evaluation of aircrew training devices. The data in this domain are distributed among numerous different publications and are written in the specialized terminology of perceptual psychology. Consequently, this information is not generally accessible to ATD engineers. The goal of the ICR study was to extract and consolidate the relevant data into an accessible format and to provide, where feasible, a synthesis of the literature which included recommendaitns relevant to equipment design. The intended output of this activity was (a) an ICR Data Base containing the available sensory/perceptual data in a form useful for specification and design purposes, and (b) an ICR Users Guide to facilitate access to the data by the ATD engineer

Centrifuge crater scaling experiment II : material strength effects by Robert M Schmidt( )

1 edition published in 1979 in English and held by 0 WorldCat member libraries worldwide

Direct simulation of large-scale explosive events can be performed at subscale using the elevated gravity field of a centrifuge. This technique allows prediction of different soil-media effects in a well-controlled manner over many orders of magnitude in explosive energy. Cratering experiments were conducted in desert alluvium, dry Ottawa sand, saturated sand, and an oil-base clay. Both lead-azide and pentaerythritol-tetra-nitrate (PETN) explosives were used. These various experiments incorporated large differences in explosive specific energy, soil cohension, soil angle of internal friction, charge weight and gravitational acceleration. Experimental results show substantial differences in cratering phenomena. At small actual yields soil cohesion dominates the cratering process. At larger yields, the cohension has little effect, but the angle of internal friction becomes an important variable because of the large overburden. The behavoir of a material such as alluvium, having nonzero values for both cohension and internal friction, shows cube-root scaling at low yields but becomes asymptotic to dry sand behavior at large yields. Neither behaves as a zero-strength material, and neither shows quarter-root scaling for scaled yields approaching megatons of TNT
Evaluation of high temperature structural adhesives for extended service : phase V( )

2 editions published between 1982 and 1987 in English and held by 0 WorldCat member libraries worldwide

This report documents the work performed by the Boeing Aerospace Company for the National Aeronautics and Space Administration, Langley Research Center, under contract NAS1-15605, Phase V. The primary objective of this program was to evaluate three experimental polymers as high temperature structural adhesives for bonding 6Al- 4V titanium and 17-7 PR stainless steel for long-term applications at 505K (450 F). The three experimental polymers were polyphenylquinoxaline (PPQ), polyimide (STPI/LaRC-2), and polyarylene ether (PAE SO2). A fourth polymer, LaRC-TPI, was evaluated as an adhesive for titanium honeycomb sandwich bonding. Surface preparations for the metal adherends were 10 volt chromic acid anodize and Pasa-Jell 107 for titanium, and 2 volt sulfuric acid anodize for the stainless steel. The test matrix for evaluating the experimental adhesives consisted of metal-to-metal titanium lap shear, crack extension, and climbing drum peel specimens tested initially at temperatures ranging from 219K ( -65 F) to 505K (450 F). Durability was determined as a function of strength retention after exposure to a variety of aerospace vehicle environments. These included humidity exposure (332K (120 F)/95% R.H.) for 1,000 hours, high temperature exposure (450K (350 F) and 505K (450 F)) for up to 3,000 hours, and stressed exposure to hydraulic fluid (Skydrol). Durability of bonded stainless steel joints was determined on an abbreviated test matrix. PPQ and STPl/LaRC-2 polymers maintained structural durability in all test environments

Hybridized Polymer Matrix Composites( )

1 edition published in 1980 in English and held by 0 WorldCat member libraries worldwide

This report describes the results of a program designed to determine the extent to which graphite fibers are released from resin matrix composites that are exposed to fire and impact conditions. The conditions evaluated were laboratory simulations of those that could exist in the event of an aircraft crash and burn situation. Another objective of the program was to evaluate the effectiveness of various hybridizing concepts in preventing this release of graphite fibers. The baseline (i.e., unhybridized) laminates evaluated were prepared from commercially available graphite/epoxy, graphite/polyimide, and graphite/phenolic materials. Hybridizing concepts investigated included resin fillers, laminate coatings, resin blending, and mechanical interlocking of the graphite reinforcement. The baseline and hybridized laminates' mechanical properties, before and after isothermal and humidity aging, also were compared. It was found that a small amount of graphite fiber was released from the graphite/epoxy laminates during the burn and impact conditions used in this program. However, the extent to which the fibers were released is not considered a severe enough problem to preclude the use of graphite-reinforced composites in civil aircraft structure. It also was found that several hybrid concepts eliminated this fiber release. Isothermal and humidity aging did not appear to alter the fiber release tendencies. Under the burn conditions used in the program, no fibers were released from the baseline graphite/phenolic laminates. Next in order of effectiveness in fiber retention was the polyimide resin, followed by the epoxy resin. (MM)
