Developing Deep Space TechnologiesI Spacecraft Structures and Mechanisms describes the integral process of developing cost-effective, reliable structures and mechanical products for space programs. Processes are defined, methods are described and examples are given. It has been written by 24 engineers in the space industry, who cover the themes of (1) ensuring a successful mission, and (2) reducing total cost through good designs and intelligent risk management. Topics include: Introduction and requirements (development process, requirements documentation, requirements definition, space mission environments) Analysis (statics, dynamics and load analysis, fatigue and fracture mechanics, mechanics of materials, strength analysis, heat transfer and thermal effects) Verification and quality assurance (verification planning, structural, mechanical and environmental testing, quality assurance and configuration control, compliance documentation, structural reliability analysis, verification criteria - factors of safety, margins of safety, fracture control, test options) Design (spacecraft configuration development, finite element analysis, mechanism development, designing for producibility, structural design, materials, designing to control loads, load cycles, sensitivity analysis) Final verification (model correlation, risk management, launch readiness reviews). For system engineers, mechanical designers, stress analysts, dynamics and load analysts, technical leads, program managers. Roger D. Werking Head, Attitude Determination and Control Section National Aeronautics and Space Administration/ Goddard Space Flight Center Extensiye work has been done for many years in the areas of attitude determination, attitude prediction, and attitude control. During this time, it has been difficult to obtain reference material that provided a comprehensive overview of attitude support activities. This lack of reference material has made it difficult for those not intimately involved in attitude functions to become acquainted with the ideas and activities which are essential to understanding the various aspects of spacecraft attitude support. As a result, I felt the need for a document which could be used by a variety of persons to obtain an understanding of the work which has been done in support of spacecraft attitude objectives. It is believed that this book, prepared by the Computer Sciences Corporation under the able direction of Dr. James Wertz, provides this type of reference. This book can serve as a reference for individuals involved in mission planning, attitude determination, and attitude dynamics an introductory textbook for stu dents and professionals starting in this field an information source for experimen ters or others involved in spacecraft-related work who need information on spacecraft orientation and how it is determined, but who have neither the time nor the resources to pursue the varied literature on this subject and a tool for encouraging those who could expand this discipline to do so, because much remains to be done to satisfy future needs. Seth Abramczyk. November 19. th. , 2021. Abstract. Accurate knowledge of the optical properties of spacecraft components, especially external components, is critical for proper spacecraft thermal design. The effective emissivity of isogrid (an array of equilateral triangular cavities) is not well understood, which poses a challenge for spacecraft thermal management. In this thesis the effective emissivity of isogrid with a prescribed base temperature and nonisothermal walls is examined. The temperature profile of the cavity’s walls and the overall effective emissivity of the cavity are found using Thermal Desktop with Monte Carlo ray tracing. The effective emissivity’s dependence on the wall height, wall thickness, wall resistance, and surface emissivity are examined. The existence of a critical wall height, and the contributing factors to this critical height, are discussed. Comparisons between isogrid and cavities with different base geometries are made. A variable emissivity isogrid spacecraft radiator concept employing the cavity effect is proposed, and mechanisms for achieving this are discussed..
