Book excerpt: This document describes the development of an accurate model for the dynamics of the Momentum Exchange Electrodynamic Reboost (MXER) system. The MXER is a rotating tether about 100-km long in elliptical Earth orbit designed to catch payloads in low Earth orbit and throw them to geosynchronous orbit or to Earth escape. To ensure successful rendezvous between the MXER tip catcher and a payload, a high-fidelity model of the system dynamics is required. The model developed here quantifies the major environmental perturbations, and can predict the MXER tip position to within meters over one orbit.Levin, E. M. and Pearson, J. and Oldson, J.

This book was released on 2013-08 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Momentum-exchange/electrodynamic reboost (MXER) tether systems may enable high-energy missions to the Moon, Mars, and beyond by serving as an 'upper stage in space'. Existing rockets that use an MXER tether station could double their capability to launch communications satellites and help improve US competitiveness. A MXER tether station would boost spacecraft from low Earth orbit to a high-energy orbit quickly, like a high-thrust rocket. Then, using the same principles that make an electric motor work, it would slowly rebuild its orbital momentum by pushing against the Earth's magnetic field-without using any propellant. One of the significant challenges in developing a momentum-exchange/electrodynamic reboost tether systems is in the analysis and design of the capture mechanism and its effects on the overall dynamics of the system. This paper will present a model for a momentum-exchange tether system that can simulate and evaluate the performance and requirements of such a system.

Book excerpt: Aimed at engineering students and professionals working in the field of mechanics of space flight, this book examines space tether systems – one of the most forward-thinking directions of modern astronautics. The main advantage of this technology is the simplicity, profitability and ecological compatibility: space tethers allow the execution of various manoeuvers in orbit without costs of jet fuel due to the use of gravitational and electromagnetic fields of the Earth. This book will acquaint the reader with the modern state of the space tether's dynamics, with specific attention on the research projects of the nearest decades. This book presents the most effective mathematical models and the methods used for the analysis and prediction of space tether systems' motion; attention is also given to the influence of the tether on spacecraft's motion, to emergencies and chaotic modes. - Written by highly qualified experts with practical experience in both the fields of mechanics of space flight, and in the teaching - Contains detailed descriptions of mathematical models and methods, and their features, that allow the application of the material of the book to the decision of concrete practical tasks - New approaches to the decision of problems of space flight mechanics are offered, and new problems are posed

Download or read book Dynamical Modelling of Space Tether written by Yi Chen and published by LAP Lambert Academic Publishing. This book was released on 2010-08 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: A space tether is a long cable used to couple satellites, probes or spacecrafts to each other or to other masses, such as a spent booster rocket, space station, or an asteroid. The motorised momentum exchange tether (MMET) was first proposed by Cartmell in 1996 and published in 1998. The system comprises a specially designed tether connecting two payload modules, with a central launcher motor. The models in this book have shown that including axial, torsional and pendular elasticity, the MMET systems have a significant bearing on overall performance and that this effect should not be ignored in future, particularly for control studies. This book provides the following points: introduction to space tethers and space tethers control, the motorised momentum exchange tether(MMET), hybrid fuzzy sliding mode control for spin-up of the MMET. The studies should help shed some light on the tether systems and hybrid control for the tether spin-up, and should be especially useful to professionals in reospace/mechanical/control engineering, or anyone else who may be of interest in utilising intelligent control for dynamical behaviors of the space tethers.

This book was released on 2018-06-24 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, we consider the dynamics of a spinning tether system in an elliptical orbit in application to the Momentum Exchange Electrodynamic Reboost system. Momentum exchange tether systems have been studied in a variety of applications since Hans Moravec's early publication. It has recently been suggested that momentum exchange systems can be enhanced with electrodynamic reboost between payload transfers. The Momentum Exchange Electrodynamic Reboost system (MXER) has a projected tether span of up to 100 km, and spins rapidly with a period of 6-7 min. It is placed in an orbit with a low perigee of about 400 km and a high apogee of about 8000 km. To capture a payload at a perigee rendezvous, within a window of a few seconds, the motion of the system has to be predicted with very high precision, having acceptable position errors on the order of 1 m. While this level of precision is routinely achieved today for conventional (non-tethered) satellites, it is much more difficult to achieve for a 100 km long flexible tether system. It is the goal of this study to investigate theoretical aspects of the dynamics and offer a practical approach to high precision dynamic modeling of a typical momentum exchange tether system.
