Available in PDF, EPUB and Kindle. Book excerpt: Optimal inplane orbital maneuvers enabling a target spacecraft in geosynchronous orbit to avoid interception by a threat in direct coasting ascent are examined. Given constant magnitude, low thrust electric propulsion, the thrust vector control history is determined to propel the spacecraft to either a maximum or minimum orbit radius in a specified time of flight. The evasive maneuver is studied from two aspects. First, an orthogonality constraint is applied at the final time of the maneuver, such that the target spacecraft's position vector is orthogonal to its velocity vector. This requirement is then removed to allow the spacecraft to travel without influence of a terminal constraint. Results demonstrate the adverse shaping effect the orthogonality constraint applies over the entire evasive maneuver. Upon completion of the evasive maneuver, the spacecraft returns in minimum time to its nominal orbit, in a position as if no evasive thrusting had occurred. Results show the time required to rendezvous with the nominal orbit may be significantly greater than the time of flight of the evasive maneuver. Optimal control is applied to formulate the evasive and rendezvous maneuvers using Euler-Lagrange theory and the calculus or variations. The behavior of the Lagrange costates is examined in terms of their effect upon solution convergence. The resulting two point boundary value problem is solved by numerical methods to yield the optimal spaceflight trajectory.

This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.
