Book Description
This report describes the activities and findings conducted under contract NAS1-19858 with NASA Langley Research Center. Subject matter is the investigation of suitable flight control design methodologies and solutions for large, flexible high-speed vehicles. Specifically, methodologies are to address the inner control loops used for stabilization and augmentation of a highly coupled airframe system possibly involving rigid-body motion, structural vibrations, unsteady aerodynamics, and actuator dynamics. Techniques considered in this body of work are primarily conventional-based, and the vehicle of interest is the High-Speed Civil Transport (HSCT). Major findings include 1) current aeroelastic vehicle modeling procedures require further emphasis and refinement, 2) traditional and nontraditional inner loop flight control strategies employing a single feedback loop do not appear sufficient for highly flexible HSCT class vehicles, 3) inner loop flight control systems will, in all likelihood, require multiple interacting feedback loops, and 4) Ref. H HSCT configuration presents major challenges to designing acceptable closed-loop flight dynamics. Newman, Brett and Kassem, Ayman Langley Research Center NAS1-19858; RTOP 537-07-24-01

Book Description
How should we organize our selection or training procedures? In what way can a flight crew mediate problems? How are we to understand reported errors? Mechanisms in the Chain of Safety presents recent findings in aviation psychology, bringing fresh insights to such questions. Aviation psychologists study personnel selection and training; they evaluate the management of flight operations, and ultimately they analyse the things that went wrong. The strong interrelation between these components allows us to talk about a chain of safety. This volume appraises this chain of safety by considering the mechanisms that determine its effectiveness - input mechanisms, coping mechanisms and control mechanisms. Each contribution discusses a component of the chain while the book as a whole emphasizes and illustrates that understanding the connections between these parts is essential for the future. By addressing these issues the book leads to further considerations such as how mistakes are linked to training and how coping mechanisms should help us to understand errors and accidents. Mechanisms in the Chain of Safety will appeal to aviation professionals (human factors experts, safety managers, pilots, ATCOs, air navigation service providers, etc.) and academics, researchers, graduates and postgraduates in human factors and psychology. Although primarily written for the aviation industry, this book will also be of interest to other high-risk dynamic activities that face similar challenges: the need to present effective and safe outcomes to the public in general and the stakeholders in particular.

Book Description
Chemical propulsion comprises the science and technology of using chemical reactions of any kind to create thrust and thereby propel a vehicle or object to a desired acceleration and speed. Cumbustion Processes in Propulsion focuses on recent advances in the design of very highly efficient, low-pollution-emitting propulsion systems, as well as advances in testing, diagnostics and analysis. It offers unique coverage of Pulse Detonation Engines, which add tremendous power to jet thrust by combining high pressure with ignition of the air/fuel mixture. Readers will learn about the advances in the reduction of jet noise and toxic fuel emissions-something that is being heavily regulated by relevant government agencies. Lead editor is one of the world's foremost combustion researchers, with contributions from some of the world's leading researchers in combustion engineering Covers all major areas of chemical propulsion-from combustion measurement, analysis and simulation, to advanced control of combustion processes, to noise and emission control Includes important information on advanced technologies for reducing jet engine noise and hazardous fuel combustion emissions
