A COMPARISON STUDY ON CONTROL MOMENT GYROSCOPE ARRAYS AND STEERING LAWS CHITIIRAN KRISHNA MOORTHY A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE GRADUATE PROGRAM IN EARTH AND SPACE SCIENCE YORK UNIVERSITY TORONTO, ONTARIO DECEMBER 2019 ©CHITIIRAN KRISHNA MOORTHY, 2019 i Abstract Current reaction wheels and magnetorquers for microsatellite are limited by low slew rate and heavily depends on orbital parameters for coverage area. Control moment gyroscope (CMG) clusters offer an alternative solution for high slew rates and rapid retargeting. Though CMGs are often used in large space missions, their use in microsatellites is limited due to the stringent mass budget. Most literature reports only on pyramid configuration, and there are no definite cross comparison studies between various CMG clusters and steering laws. In this research, a generic tool in Matlab and Simulink is developed to further understand CMG configurations and steering laws for a microsat mission. Various steering laws necessary for mitigating singularities in CMG clusters are compared in two distinct missions. The simulation results were evaluated based on the pointing accuracy, platform jitter, and pointing stability achieved by the spacecraft for each combination of CMG clusters, steering laws and trajectories. The simulation results demonstrate that the pyramid cluster is marginally better than the rooftop cluster in pointing accuracy. The comparison of steering laws shows that, counterintuitively, Singularity Robust steering law, which passes through singularities, outperforms both Moore-Penrose and Local Gradient methods for almost all evaluation criteria for the two missions it was tested on. -

Design Evolution and AHP-Based Historiography of Lifting Reentry Vehicle Space Programs
AIAA 2016-5319 AIAA SPACE Forum 13 - 16 September 2016, Long Beach, California AIAA SPACE 2016 Design Evolution and AHP-based Historiography of Lifting Reentry Vehicle Space Programs Loveneesh Rana∗ and Bernd Chudoba y University of Texas at Arlington, TX-76019-0018 The term \Historiography" is defined as the writing of history based on the critical examination of sources. In the context of space access systems, a considerable body of lit- erature has been published addressing the history of lifting-reentry vehicle(LRV) research. Many technical papers and books have surveyed legacy research case studies, technology development projects and vehicle development programs to document the evolution of hy- personic vehicle design knowledge gained from the early 1950s onwards. However, these accounts tend to be subjective and qualitative in their discussion of the significance and level of progress made. Even though the information addressed in these surveys is consid- ered crucial, it may lack qualitative or quantitative organization for consistently measuring the contribution of an individual program. The goal of this study is to provide an anatomy aimed at addressing and quantifying the contribution of legacy programs towards the evolution of the hypersonic knowledge base. This paper applies quantified analysis to legacy lifting-reentry vehicle programs, aimed at comprehensively capturing the evolution of LRV hypersonic knowledge base. Beginning with an overview of literature surveys focusing on hypersonic research programs, a com- prehensive list of LRV programs, starting from the 1933 Silvervogel to the 2015 Dream Chaser, is assembled. These case-studies are assessed on the basis of contribution made towards major hypersonic disciplines. -

SPECULATION ON ARCHITECTURE IN THE ABSENCE OF GRAVITY Speculation on Architecture in the absence of Gravity. How might architectural elements and design strategies function in outer space? Hermann Matamu 132 8392 Master Thesis explanatory document: Jeanette Budgett Abstract The evolution of architecture has been driven by a combination of elements such as style, context, materiality, aesthetic and technology. The development of materials and the technological advancements of the human race are conveyed through architecture; from the technical expertise of the ancient Egyptians in pyramid construction, to the engineering feats of the Eiffel Tower in Paris, to the physical realisation of Gehry’s Guggenheim through computer modelling. Architecture is a continuous evolution which revolves around the progression of the human race in all fields of life. Space habitation presents the next step in this architectural evolution, in which Space tourism acts as the stepping stone for the transition of architectural design beyond Earth. Space design has been produced largely without architectural input. The aim of this project is to introduce an architectural sensibility, and to investigate the impact an absence of gravitational force has on architecture. The research follows the transition of architectural design from an environment of gravity to one without, by reviewing both current literature and precedent case studies. i Acknowledgements As this chapter in my life comes to an end, I would like to thank all those who made it a memorable one. Firstly, I would like to thank my supervisor, Jeanette Budgett. Thank you for your patience, support and constant encouragement throughout my research, your knowledge and time have been instrumental in the development of this project. -

Walking the High Ground: the Manned Orbiting Laboratory And
Walking the High Ground: The Manned Orbiting Laboratory and the Age of the Air Force Astronauts by Will Holsclaw Department of History Defense Date: April 9, 2018 Thesis Advisor: Andrew DeRoche, Department of History Thesis Committee: Matthew Gerber, Department of History Allison Anderson, Department of Aerospace Engineering 2 i Abstract This thesis is an examination of the U.S. Air Force’s cancelled – and heretofore substantially classified – Manned Orbiting Laboratory (MOL) space program of the 1960s, situating it in the broader context of military and civilian space policy from the dawn of the Space Age in the 1950s to the aftermath of the Space Shuttle Challenger disaster. Several hundred documents related to the MOL have recently been declassified by the National Reconnaissance Office, and these permit historians a better understanding of the origins of the program and its impact. By studying this new windfall of primary source material and linking it with more familiar and visible episodes of space history, this thesis aims to reevaluate not only the MOL program itself but the dynamic relationship between America’s purportedly bifurcated civilian and military space programs. Many actors in Cold War space policy, some well-known and some less well- known, participated in the secretive program and used it as a tool for intertwining the interests of the National Aeronautics and Space Administration (NASA) with the Air Force and reshaping national space policy. Their actions would lead, for a time, to an unprecedented militarization of NASA by the Department of Defense which would prove to be to the benefit of neither party. -

ASCMG-JGCD-Final
JOURNAL OF GUIDANCE,CONTROL, AND DYNAMICS Vol. , No. , Adaptive Singularity-Free Control Moment Gyroscopes V. Sasi Prabhakaran∗ Akrobotix LLC, Syracuse, New York 13202 and Amit Sanyal† Syracuse University, Syracuse, New York 13244 DOI: 10.2514/1.G003545 Design considerations of agile, precise, and reliable attitude control for a class of small spacecraft and satellites using adaptive singularity-free control moment gyroscopes (ASCMG) are presented. An ASCMG differs from that of a conventional control moment gyroscopes (CMG) because it is intrinsically free from kinematic singularities and so does not require a separate singularity avoidance control scheme. Furthermore, ASCMGs are adaptive to the asymmetries in the structural members (gimbal and rotor) as well as misalignments between the center of mass of the gimbal and rotors. Moreover, ASCMG clusters are highly redundant to failure and can function as variable- and constant-speed CMGs without encountering singularities. A generalized multibody dynamics model of the spacecraft–ASCMG system is derived using the variational principles of mechanics, relaxing the standard set of simplifying assumptions made in prior literatureonCMG. The dynamics model so obtained shows the complex nonlinearcoupling between the internal degrees of freedom associated with an ASCMGand the spacecraft attitude motion.The general dynamics model is then extended to include the effects of multiple ASCMG, called the ASCMG cluster, and the sufficient conditions for nonsingular cluster configurations are obtained. The adverse effects of the simplifying assumptions that lead to the intricate design of the conventional CMG, and how they lead to singularities, become apparent in this development. A bare-minimum hardware prototype of an ASCMG using low-cost commercial off-the-shelf components is developed to show the design simplicity and scalability.
