Book Synopsis Constant-Thrust Orbit-Raising Transfer Charts by :
Download or read book Constant-Thrust Orbit-Raising Transfer Charts written by and published by . This book was released on 1993 with total page 23 pages. Available in PDF, EPUB and Kindle. 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 ...

Book Synopsis Optimal Continuous-Thrust Orbit Transfers by : James Dana Thorne
Download or read book Optimal Continuous-Thrust Orbit Transfers written by James Dana Thorne and published by . This book was released on 1996-06-01 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: The minimum time orbital transfer problem for spacecraft with steerable, continuous thrust of constant magnitude may be solved using Euler- Lagrange theory, which leads to the optimal control law in terms of Lagrange multipliers. However, the initial values of the Lagrange multipliers are not known from the orbital boundary conditions. Using analytical and empirical results, the optimal initial costates are modeled as functions of the problem parameters which are the initial thrust acceleration, A, and the final orbit radius, H, in canonical units. For circle to circle, coplanar orbit transfers, these approximate initial costate models lead to convergence in the shooting method for all practical values of A and H. The models also lead to convergence for a wide rang of other problems, including circle to hyperbola transfers and non-coplanar transfers. To counter the extreme sensitivity to small changes in the initial costate conditions, a dynamic step limiter is introduced which improve the convergence properties.

Book excerpt: Published for the American Astronautical Society (AAS). The August 1993 conference was hosted by the AAS and co-sponsored by the American Institute of Aeronautics and Astronautics. The proceedings cover topics including attitude determination and control, TOPEX orbit determination and control, orbit determination, orbit transfer, tethers, mission analysis (planetary/Earth/general/trajectories), navigation, rendezvous, attitude dynamics and control, flexible body dynamics and control, and orbit dynamics. Additional papers from the conference are available on a microfiche supplement (v.70, AAS Microfiche Series); these are represented in the present volumes by an abstract with reference to the supplement.

Book Synopsis Fundamentals of Astrodynamics and Applications by : D.A. Vallado
Download or read book Fundamentals of Astrodynamics and Applications written by D.A. Vallado and published by Springer Science & Business Media. This book was released on 2001-06-30 with total page 1002 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Astrodynamics and Applications is rapidly becoming the standard astrodynamics reference for those involved in the business of spaceflight. What sets this book apart is that nearly all of the theoretical mathematics is followed by discussions of practical applications implemented in tested software routines. For example, the book includes a compendium of algorithms that allow students and professionals to determine orbits with high precision using a PC. Without a doubt, when an astrodynamics problem arises in the future, it will become standard practice for engineers to keep this volume close at hand and `look it up in Vallado'. While the first edition was an exceptionally useful and popular book throughout the community, there are a number of reasons why the second edition will be even more so. There are many reworked examples and derivations. Newly introduced topics include ground illumination calculations, Moon rise and set, and a listing of relevant Internet sites. There is an improved and expanded discussion of coordinate systems, orbit determination, and differential correction. Perhaps most important is that all of the software routines described in the book are now available for free in FORTRAN, PASCAL, and C. This makes the second edition an even more valuable text and superb reference.

Book Synopsis Analytical Equations for Orbital Transfer Maneuvers of a Vehicle Using Constant Low Thrust by :
Download or read book Analytical Equations for Orbital Transfer Maneuvers of a Vehicle Using Constant Low Thrust written by and published by . This book was released on 1981 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this study is to derive a set of equations which predict the results of orbital maneuvers of vehicles using constant low thrust. These equations are developed by simplifying the problem to circular orbits in a two-body dynamic system. The results are presented in three parts. The first part solves for the equation of the coplanar radius change problem. The second finds the equation for the minimum fuel inclination change problem. The third part of this study puts the equations from the first two parts together to solve a minimum fuel transfer problem involving both radius and inclination changes. The solution of the minimum fuel transfer problem is not to perform the total radius change and then perform the total inclination change. Instead, the solution is to perform both radius and inclination changes on a per orbit basis.

Book Synopsis Nearly Circular Transfer Trajectories for Descending Satellites by : George M. Low
Download or read book Nearly Circular Transfer Trajectories for Descending Satellites written by George M. Low and published by . This book was released on 1959 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simplified expressions describing the transfer from a satellite orbit to the point of atmospheric entry are derived. The expressions are limited to altitude changes that are small compared with the earth's radius, and velocity changes that are small compared with satellite velocity. They are further restricted to motion about a spherical, nonrotating earth. The transfer trajectory resulting from the application of thrust in any direction at any point in an elliptic orbit is considered. Expressions for errors in distance (miss distance) and entry angle due to an initial misalinement and magnitude error of the deflecting thrust are presented. The guidance and accuracy requirements to establish a circular orbit, and orbit corrections are also discussed.
