Ein lebendiger Abriß der Theorie der Umlaufbahnen, geschrieben von einem Spezialisten, der für Computersimulationen und Systemanalysen der Saturn-V-Rakete, des Projektes Skylab und vieler anderer Projekte zuständig war. Die Diskussion umfaßt auch unkonventionelle Ansätze und Paradoxa. Schwerpunkte liegen unter anderem auf Raketenantrieben, Optimierung des Verhältnisses zwischen Nutzlast und Treibstoffverbrauch und der Wechselwirkung zwischen Raumfahrzeugen und Raumobjekten.

Flying is an extremely safe way to travel. Fewer than 14,000 individuals perished in U.S. airline disasters during the twentieth century. In contrast, nearly three times as many people lose their lives in automobile accidents every year. Yet plane crashes have a tremendous impact on public perceptions of air safety in the United States. When a crash occurs domestically, media coverage is immediate and continuous. Government teams rush to investigate, elected officials offer condolences and promise to find the cause, and airlines and plane manufacturers seek to avoid responsibility. Regulations are frequently proposed in response to a particular incident, but meaningful change often does not occur. In The Plane Truth, Roger Cobb and David Primo examine the impact of high-visibility plane crashes on airline transportation policy. Regulation is disjointed and reactive, in part due to extensive media coverage of airline disasters. The authors describe the typical responses of various players—elected officials, investigative agencies, airlines, and the media. While all agree that safety is the primary concern in air travel, failure to agree on a definition of safety leads to policy conflicts. Looking at all airline crashes in the 1990s, the authors examine how particular features of an accident correspond to the level of media attention it receives, as well as how airline disasters affect subsequent actions by the National Transportation Safety Board, Federal Aviation Administration, and others. Three accidents are considered in detail: USAir flight 427 (September 1994), ValuJet flight 592 (May 1996), and TWA flight 800 (July 1996). The authors also discuss how the September 11 terrorist attacks turned attention away from safety and toward security. Cobb and Primo make several policy recommendations based on their findings. These include calling on lawmakers and regulators to avoid reactive regulation and instead to focus on systematic problems in a
Orbital mechanics is a cornerstone subject for aerospace engineering students. However, with its basis in classical physics and mechanics, it can be a difficult and weighty subject. Howard Curtis - Professor of Aerospace Engineering at Embry-Riddle University, the US's #1 rated undergraduate aerospace school - focuses on what students at undergraduate and taught masters level really need to know in this hugely valuable text. Fully supported by the analytical features and computer based tools required by today's students, it brings a fresh, modern, accessible approach to teaching and learning orbital mechanics. A truly essential new resource. - A complete, stand-alone text for this core aerospace engineering subject - Richly-detailed, up-to-date curriculum coverage; clearly and logically developed to meet the needs of students - Highly illustrated and fully supported with downloadable MATLAB algorithms for project and practical work; with fully worked examples throughout, Q&A material, and extensive homework exercises.
This title was first published in 2003.Airline operating profits are well known to be volatile, and the global industry aggregate figures conceal wide differences in performance between carriers. The fundamental reasons for the poor performance of the industry as a whole were in the early 1990's that output ran too far ahead of demand, and the yield earned on output sold was insufficient to cover costs. In strategic context, this second edition uses a simple yet powerful model to explore linkages between the fundamentals of airline economics and the volatility of industry results at the operating level. Its five parts look in turn at strategic context, supply side, demand side, network management and a general conclusion.
