The procurement of medium and high altitude UAS has dramatically increased since 1988. The DOD now spends billions of dollars annually to research, test, develop and procure medium and high altitude UAS for all military services. In an effort to rapidly field these very capable systems to contribute to Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF), there appeared to be two key areas of concern. The magnitude of funding involved and the apparent similarity of UAS capabilities created an indicator for potential inefficiencies in the acquisition process utilized by DOD. The key medium and high altitude UAS programs identified in this study were the MQ-1B Predator, MQ-1C Sky Warrior, MQ-9 Reaper, RQ-4 Global Hawk and the Broad Area Maritime Surveillance (BAMS). This thesis analyzed the scope of funding involved, the capability similarities and the respective payload considerations of these key medium and high altitude UAS. Conclusions and subsequent recommendations were based off quantitative and qualitative analysis conducted and the respective findings.

This book presents novel methods for the simulation of damage evolution in aerospace composites that will assist in predicting damage onset and growth and thus foster less conservative designs which realize the promised economic benefits of composite materials. The presented integrated numerical/experimental methodologies are capable of taking into account the presence of damage and its evolution in composite structures from the early phases of the design (conceptual design) through to the detailed finite element method analysis and verification phase. The book is based on the GARTEUR Research Project AG-32, which ran from 2007 to 2012, and documents the main results of that project. In addition, the state of the art in European projects on damage evolution in composites is reviewed. While the high specific strength and stiffness of composite materials make them suitable for aerospace structures, their sensitivity to damage means that designing with composites is a challenging task. The new approaches described here will prove invaluable in meeting that challenge.

Fragen der gesellschaftlichen Verantwortung von Unternehmungen stehen seit geraumer Zeit im Mittelpunkt der wissenschaftlichen und praktischen Diskussion. Ursachlich dafur sind die sich verandernden Rahmenbedingungen der globalisierten Wirtschaftssysteme und der damit verstarkte nationale und internationale Wettbewerb auf den Beschaffungs- und Absatzmarkten, der klimatische und demographische Wandel, die verstarkte Umweltbelastung, die Verknappung der naturlichen Ressourcen, die steigende Digitalisierung und nicht zuletzt die leeren Staatskassen und die damit einhergehenden Streichungen sozialer staatlicher Leistungen. Vor diesem Hintergrund streben die Herausgeber Prof. Dr. Dr. h. c. mult. Heribert Meffert, Prof. Dr. Peter Kenning und Prof. Dr. Manfred Kirchgeorg mit Sustainable Marketing Management Texte und Cases des Sustainable Marketing ein Sammelwerk an, das erstmals das Thema nachhaltige Unternehmensfuhrung im Gebiet des Marketing aus Wissenschafts- und Praxisperspektive integriert betrachtet. Das Ziel des Sammelwerks ist es, zunachst den Begriff des Sustainable Marketing Management wissenschaftlich-konzeptionell zu erlautern, um der gegenwartigen Inhaltsentleerung dieses und ahnlicher Begrifflichkeiten entgegenzuwirken. Ferner soll dem Leser entlang der Stufen des entscheidungsorientierten Managementansatzes (Ziele, Strategien, Umsetzung, Kontrolle) aus Wissenschaft und Praxis aufgearbeitete Best Practice-Praxisbeispiele prasentiert werden. So kann der Leser das eigene (unternehmerische) Handeln vergleichen und ggfs. entsprechend anpassen bzw. neu ausrichten. Dazu sollen insb. die Fallstudienbeitrage sowohl von einem Vertreter aus der Wissenschaft als auch aus der Praxis gemeinsam verfasst werden, um eine ganzheitliche Perspektive zu gewahrleisten und dem integrativen Gedanken des Sammelwerkes Rechnung zu tragen. ​

Fuel cell technology is the most exciting and legitimate alternative source of power currently available to us as world resources of non-renewable fuel continue to be depleted. No other power generating technology holds the same benefits that fuel cells offer, including high reliability and efficiency, negligible environmental impact, and security of supply. Fuel cells run on hydrogen - the simplest and most plentiful gas in the universe - although they can also run on carbon monoxide, methane, or even coal. Their applications are diverse, from powering automobiles, buildings and portable electronics, to converting methane gas from wastewater plants and landfills into electricity. Fuel Cells, Engines and Hydrogen is a controversial text that challenges the accepted industry parameters for measuring fuel cell performance and efficiency. Based on his inter-disciplinary experience in the fields of power, nuclear power, and desalination, the author contends that the development potential of the fuel cell is related to the quantity fuel chemical exergy, which, like electrical potential, is a quantitative measure of work done. The fuel cell community currently characterises these devices in terms of the enthalpy of combustion (calorific value) - however the author argues a correct, qualitatively different and fourfold larger characterisation is via the fuel chemical exergy, in units of work, and not energy. He asserts that the distortion introduced by this accepted perspective needs to be corrected before relatively efficient fuel cells, integrated with comparatively low performing gas turbines, reach the market. Fuel Cells, Engines and Hydrogen features a foreword by Dr Gerry Agnew, Executive VP Engineering of Rolls Royce Fuel Cells Systems Ltd. It is essential reading for all engineers involved with fuel cells and/ or the manufacture of hydrogen from natural gas, as well as academics in related disciplines such as thermodynamics, physical chemistry, materials, physics, mechanical and chemical engineering.

This volume considers the shock response spectrum, its various definitions, properties and the assumptions involved in its calculation. In developing the practical application of these concepts, the forms of shock most often used with test facilities are presented together with their characteristics and indications of how to establish test configurations comparable with those in the real, measured environment. This is followed by a demonstration of how to meet these specifications using standard laboratory equipment -- shock machines, electrodynamic exciters driven by a time signal or a response spectrum -- with a discussion on the limitations, advantages and disadvantages of each method.

The purpose of this monograph is to prove that by 2015 uninhabited combat aerial vehicles will have reached a level of capability at which they will be of utility to the joint force commander. This is important to the military to understand because the United States Air Force is going to begin fielding uninhabited combat aerial vehicles in large numbers by that time. Because these uninhabited combat aerial vehicles are going to end up augmenting or replacing other weapon systems in the joint combatant commander's list of force options, the United States military needs to know if they will be useful. The United Stated military must be ready for the future-operating environment predicted by the Central Intelligence Agency and the Joint Staff. In order to do this, the Joint Staff has enumerated five required capabilities if joint forces in the near future: rapid global projection; forcible entry into a joint operations area; immediate and synchronized employment of scaleable joint forces tailored to conduct simultaneously a broad range of joint military operations utilizing unified action; sustainment for extended periods in an austere environment or under anti-access or area denial conditions; and continuous joint C4ISR employment and knowledge generation fusion. Additionally, given the world environment, the author has added two capabilities which will be of great benefit to the joint combatant commander: the ability to employ a weapons system in diplomatically sensitive situations and the capability to execute a portion of the theater missile defense mission. This makes a list of seven capabilities which are the criteria that define whether the uninhabited combat aerial vehicle will be of utility to the joint combatant commander. The uninhabited combat aerial vehicle will be capable of all of those missions by 2015. The author concludes that not only will uninhabited combat aerial vehicles be of utility, but they will be highly sought after. Because of this predicted increase in interest in and dependence on UCAVs, the United States military must be ready to employ these UCAVs properly by: first, educating joint force commanders and planners about their increasing capabilities and inherent limitations and, second, ensuring their integration into the common operational picture systems and tactical data links of the near future
