43	Nitrogen Tetroxide to Mixed Oxides of Nitrogen: History, Usage, Synthesis, and Composition Determination Andrew W Head (11181636) 22 November 2021 (has links) <div>Since as early as the 1920s, dinitrogen tetroxide (N2O4) has been regarded as a promising oxidizer in rocket propulsion systems. In more recent times, its predecessor, mixed oxides of nitrogen (MON), remains a top contender among oxidizers, due to its unique characteristics such as low freezing temperature and compatibility with common spacecraft materials. Today, these N2O4-based oxidizers are the preferred choice in many upper stages, launch escape systems, reaction control systems, liquid apogee engines, and in-space primary propulsion systems. N2O4-based oxidizers are a key factor in rocket propulsion, and thoroughly understanding their history, development, characteristics, synthesis, and composition analysis are crucial for space exploration today and into the future.<br><br></div><div>To fully understand and predict the physical properties of a MON sample, it is important to measure and quantify its chemical composition. The recommended method for MON composition analysis, as prescribed by the Department of Defense’s Defense Specification (MIL-SPEC) document on N2O4, involves the oxidation of NO and dinitrogen trioxide (N2O3) in the MON sample to determine their amounts. An equation unofficially called the “MIL-SPEC equation” is then used to determine the amount of NO needed to mix with N2O4 to synthesize that particular MON sample. However, no explanation is given as to how the equation was derived, or its significance.<br><br></div><div>This thesis aims to collect and organize key information on the synthesis, handling, and composition analysis of MON propellant. First, the history of development of N2O4-based oxidizers was researched, and current and future uses of N2O4 and MON propellants were identified. Then a method for synthesis and composition analysis was devised and tested. Water contamination was expected of skewing the results, so the process of water contamination was examined analytically. Then a detailed derivation of the MIL-SPEC equation was conducted, to fully understand its mechanics. An attempt was then made to reverse-engineer an unexplained numerical value in the equation, labeled by the author as the “solubility factor”. Several derivations were provided with varying degrees of complexity, producing alternative solubility factors of varying accuracies. Finally, experimental data was applied to these derived, hypothetical solubility factors and the MIL-SPEC solubility factor, with the intent of determining whether improvements could be made to the MON composition determination process.<br><br></div><div>The results suggest that the MIL-SPEC equation is sufficient for providing a relatively accurate measurement of the composition of a MON sample, while also being easy to implement, both in taking the necessary measurements and in conducting the numerical calculation. However, some minor adjustments to the equation could produce consistently more accurate composition measurements without adding any more difficulty or complication.</div> Aerospace Engineering rocket propellant oxidizer nitrogen dinitrogen tetroxide nitric oxide mixed oxides MON NTO N2O4 mixed oxides of nitrogen nitrogen tetroxide dinitrogen tetroxide nitric oxide NO2 space propulsion spacecraft astronautics aerospace engineering missile launch history synthesis composition equation derivation NASA Department of Defense Air Force freezing point corrosion solubility oxidation MIL-SPEC military specification

46	Applications of Digital Engineering Tenets to Naval Special Warfare Requirement(s) Definition David Novotney (15360427) 28 April 2023 (has links) <p> The world continues to advance at a hastening pace towards a technology enabled, digital-centric future. Legacy organizations, not born in the ‘digital age’ are examining methods to adapt through Digital Transformation (DT). The US Department of Defense (DoD) is one such organization. The DoD emerged their 2018 Digital Engineering Strategy intending on transforming the enterprise from one with ‘engineering process [that] are document-intensive and stove-piped, leading to extended cycle times with systems that are cumbersome to change and sustain’ to one that is ‘transforming its engineering practices to digital engineering, incorporating technological innovations into an integrated, digital, model-based approach’. </p> <p> The 2018 Strategy acknowledges that the integration of digital engineering will not be exclusive to the engineering communities of the DoD; rather, the integration will impact the ‘research, requirements, acquisition, test, cost, sustainment and intelligence communities’. While the Strategy is designed to explain the ‘what’ necessary to integrate digital engineering, the various DoD Services (and their subordinates) will need to develop the ‘how’ regarding implementation that is culturally appropriate to their commands.</p> <p> The study sought to examine ‘how’ implementation of digital engineering tenets may be appropriated to the existent culture of one US Special Operations Command subordinate at the Echelon III level (namely Naval Special Warfare Group – FOUR). The results of this study are intended to provide understanding and illuminate meaning behind those themes in Digital Engineering that Subject Matter Experts within Naval Special Warfare view as suitably adaptable to their processes. The intent is to provide themes with utility towards further efforts and research aimed at phasing Digital Transformation initiatives at Naval Special Warfare Group – FOUR.</p> Business systems in context Product Lifecycle Management Department of Defense Naval Special Warfare DoD Requirements Acquisitions Engineered to Order Digital Engineering Digital Transformation US Special Operations Command Culture USSOCOM NSW Naval Special Warfare Group - FOUR Sustainment PLM Organizational Change Organizational Change Management Digital Thread PLM Strategy Process Process Change Theme
47	Same-Sex Sexual Assault in the Military Croft, Lauren 01 May 2015 (has links) Sexual assault in the military is a large concern for the Department of Defense. They recognize it as an important and complex problem that needs to be addressed. In recent years, efforts have been initiated in order to improve the handling of sexual assault cases and data retention. An entirely new program has been created in order to address these cases. Focusing on the occurrence of same-sex assaults heightens the sensitivity of matters. This is due to the precarious and only very recent acceptance of homosexuals in the military. In the past, service members, homosexual or otherwise, may have been concerned with having any connection to homosexual acts. This is because such acts could result in removal from the military. However, in 2011 the “Don’t Ask, Don’t Tell” Repeal Act went into effect. This act allowed for the open service of homosexuals in the military. Around this same time period, reports from the Department of Defense indicated a rise in the number of sexual assault reports. This thesis analyzes the affect that policies from the Department of Defense and legislation such as the “Don’t Ask, Don’t Tell” Repeal Act have on reports of same-sex sexual assault in the military. Through research, this thesis finds that the enactments of various policies have had a measurable impact on treatment of same-sex sexual assault reports in the military, though not necessarily in the way certain media reports might suggest. This thesis also examines the history concerning homosexual service in the military, in order to provide a picture of the national attitudes towards homosexual service in the military, and why certain groups may blame the Lesbian, Gay, Bisexual, and Transgender for this rise in reports.
