Book excerpt: Electrodynamic tethers can be employed to effect spacecraft orbital maneuvering outside of Keplerian motion without incurring the mass penalty of traditional propulsion systems. Recently, several studies have been conducted to establish a framework for guidance and control of such orbit maneuvers, including the optimization of a particular maneuver, the orbit transfer. This thesis provides an overview of the concept of electrodynamic tether employment, summarizes research in the field, and catalogues recent proposals. Two minimum-time orbit transfer problems are considered - an orbit raising and a deorbit problem. Both formulations use an identical set of initial conditions for the spacecraft. In the case of the orbit raising problem formulation, the terminal manifold requires an increase in semimajor axis and return to initial eccentricity and inclination values. Other orbital elements are unconstrained. For the deorbit case, optimal control is developed for a minimum time decrease in semimajor axis; the remaining orbital elements are unconstrained. The totality of optimality conditions for both cases of using electrodynamic tethers to maneuver from an initial orbit is examined. Observations and recommendations for future work are presented in the conclusions.

Download or read book Space Vehicle Maneuvering, Propulsion, Dynamics and Control written by Ranjan Vepa and published by Springer. This book was released on 2024-12-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook introduces space vehicle maneuvering, propulsion, dynamics and control, and discusses the space environment and its influence on the spacecraft propulsion system. This is followed by an in depth description of Keplerian celestial mechanics, co-planar and non-planar orbital transfers involving both impulsive and continuous manoeuvers, and perturbation effects that characterize the real non-Keplerian nature of orbital motion. Dr. Vepa then explains the use of restricted two-body and three-body dynamics as descriptors of spacecraft motion, the limitations of these approach in terms of orbital perturbations and an understanding of the physical source and influence of these perturbations, and principles of the optimal synthesis of trajectories. Featuring many exercises, design case studies, and extensive use of MATLAB/SIMULINK and MATLAB analytical tools, the book is ideal for graduate students, post graduate students, researchers, as well professionals in the industry.

This book was released on 1970 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: A high performance LF2/LH2 maneuvering propulsion system has been defined, which provides an in orbit delta V capability in excess of 21,000 ft/sec with a 2000 pound payload. The system, which is designed for launch into a 100 nautical mile polar orbit with the Titan IIID, weighs 18,000 pounds fully loaded, has instant response and multi-start capability, while providing a nominal space residence duration of 14 days. Longer orbital stay times (up to 180 days) can be accommodated with some design modification without significantly degrading performance. This design can be used as the basis of a ground test article to demonstrate the feasibility of technical concepts applicable to a wide range of high performance stage sizes. (Author).

Book excerpt: This report outlines a method to generate minimum-fuel trajectories between coplanar circular orbits for a vehicle with constant thrust. The rocket equation models the effects of continuous fuel expenditure while also serving to recast the solution in terms of accumulated velocity change. These orbit-raising solutions are globally mapped with no restrictions on initial thrust magnitude, intermediate eccentricity, or number of revolutions of the central body. Several examples are presented to verify the transfer charts and familiarize the reader with their use. These charts are useful tools for mission planners and satellite designers to assess preliminary fuel requirements for constant-thrust systems or to compare different propulsion technologies ...

Download or read book Technology and Advanced Development for a Non-Toxic Orbital Maneuvering System and Reaction Control System for Orbiter Upgrade written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-11 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: NASA intends to pursue technology applications to upgrade the Space Shuttle Orbiter OMS and RCS systems with non-toxic propellants. The primary objectives of an upgraded OMS/RCS are improved safety and reliability, reduced operations and maintenance costs while meeting basic OMS/RCS operational and performance requirements. The OMS/RCS has a high degree of direct interaction with the crew and requires subsystem and components that are compatible with integration into the orbiter vehicle with regard to external mold-line, power and thermal control The non-toxic propulsion technology is also applicable to future Human Exploration and Development of Space (HEDS) missions. The HEDS missions have similar requirements for attitude control and lander descent/ascent propulsion and which will emphasize the use of In-Situ Resource for propellants. When used as a regenerative coolant as in the Shuttle Orbiter OMS combustion chamber, non-toxic fuels such as ethanol are limited in their cooling capacity by the bulk temperature rise permitted to prevent film boiling or possible coking. Typical regeneratively cooled chambers are constructed from highly conductive copper, which maximizes heat transfer, or from low conductivity materials like stainless steel that can also exacerbate cooling problems. For an ethanol cooled application the heat transfer into the fluid must be controlled to reduce the fuel coolant bulk temperature rise. An approach to provide this control is the subject of this report. This report is being issued to document work done by Aerojet on NASA contract NAS 8-98042. Specifically, this project investigates of the use of ethanol, a designated non-toxic fuel, as a coolant for the Space Shuttle Orbital Maneuvering System Engine combustion chamber. The project also addresses a cost reducing fabrication technique for construction of such a combustion chamber. The study contained three major sub-tasks: an analytical investigation and trade study which included layout

Book excerpt: From the authors' abstract: "This analytical study looks at the importance of Deep Space Operations and recommends an approach for senior policy leaders. Section 1 presents a capability requirements definition with candidate solutions and technology strategies. Section 2 recommends an acquisition and organizational approach. Section 3 provides an extended strategic rationale for deep space operations as a national priority." And from the Introduction: [this essay] "presents capability requirements, potential solutions, and strategic rationale for achieving movement and maneuver advantage in deep space. In this context, deep space is anything beyond geosynchronous Earth orbit (GEO). Driving the research are two primary assumptions underpinning the need for investment in deep space propulsion. The first assumption is that growing international activity, commerce, and industry in space extends the global commons, thus creating a military-economic imperative for the United States Department of Defense (DoD) to expand its protection of U.S. interests by defending space lines of communication. Although there are wide-ranging reasons to expand the space-faring capabilities of the human species, from the capitalistic to the existential, the fact of its occurrence offers the U.S. immense strategic opportunity. Section 1, operating on this assumption, recommends capability-based requirements for deep space operations given a projected future operating environment.The second driving assumption underpinning this study is that improved movement and maneuver capabilities in deep space offer a wide array of benefits for the current National Security Enterprise, and for this reason alone demands attention in the form of disciplined investment. Furthermore, because the core functional capability required for deep space operations is in-space propulsion, the requirement necessitates a materiel solution.
