In the late 1980s the Daily Telegraph transformed the traditionally dry and stolid world of obituaries, ushering in a new way of writing about the dead that was vivid, gently subversive and richly comic. Telegraph obituaries became a byword for entertaining journalism, celebrated for their deadpan tone and sympathetic eye for human quirks and eccentricities.Here is a gallery of the most entertaining of these eccentric lives from the recent past, most of them never before published in book form. They amply demonstrate that in an age of committees and bureaucracy and increasing pressure to conform, eccentrics of all kinds have continued to thrive. From the oddball to the prophet, they have ploughed their own furrow. These miniature biographies are charming, funny, oft en moving, but always compulsively readable.

This is the first Structural Dynamics book focused on this indispensable aspect of liquid rocket engine design. This book begins by reviewing basic concepts in Structural Dynamics, including the free and forced response of SDOF and MDOF systems, along with some discussion of how numerical solutions are generated. The book then moves to a discussion of specific applications of these techniques in LREs, progressing from component level (turbomachinery and combustion devices), up through engine system models, and finally to integration with a launch vehicle. Clarifies specific topics including the Campbell and SAFE Diagrams for resonance identification in turbomachinery, the complications of component analysis in the pump side due to a host of complication factors such as acoustic/structure interaction, the "side-loads" fluid/structure interaction problem in overexpanded rocket nozzles, and competing methods for generation overall engine system interface loads. Includes specific examplesfor illustration while closing with rotordynamic analysis, dynamic data analysis, and vibroacoustics.
