Download or read book Optimized Performance of an Articulated Gravity Gradient Satellite at Synchronous Altitude written by P. C. Hughes and published by . This book was released on 1966 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: A geometrically and dynamically symmetrical articulated satellite is considered for possible application at synchronous altitudes. The perturbing influence of solar radiation pressure on the two vertical hinged booms is studied, and the small-angle equations of motion derived. From these equations, both the transient and steady-state pointing performance are optimized through a computer search. Pointing errors of the order of two degrees, and damping times less than one orbit are shown to be possible for a weight expenditure of forty-five pounds (satellite payload weight = 250 pounds). (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Octogenarian aerospace engineer Peter Hughes identified 6 critical points in his life at which an important decision was required, and where the rest of his life could have been quite different, depending on that decision. In every case, he was completely free to make the decision. In Six Degrees of Freedom, Hughes reflects on a full lifetime, including several work environments, his contributions to the aerospace industry (including work on the Canadarm), a passion for applied mathematics, family life, business and entrepreneurship, travel experience, and medical science. In so doing, and through his wry humor, he provides the reader thoughtful insight and useful life and career lessons.

Download or read book On the Use of Flexible Strings in Gravity gradient Stabilization Systems written by Garg, S. C and published by Institute for Aerospace Studies, University of Toronto. This book was released on 1969 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: A related family of three gravity-gradient-stabilized synchronous equatorial satellites is analyzed considering small-angle attitude dynamics in the orbital plane. A characteristic feature is the use of long thin perfectly flexible strings to achieve the desired mass distribution, which eliminates the solar radiation pressure and heating effects inherent in conventional rigid-boom designs. Damping is achieved by articulated hinges and magnetically-anchored viscous fluid dampers. The designs are optimized using a numerical gradient-search technique and considering the time to damp to half amplitude of the least-damped mode as the performance index. The pointing performance is found to be relatively insensitive to parameter variations. Optimized results are presented for a series of constrained satellite configurations. (Author).
